Secretary of Business, Consumer Services, and Housing, Secretary of California Natural Resources Agency. >> Brian Cash here for Wade Crot. >> Secretary of California Health and Human Services. Speaker, the Assembly appointee representing the interests of private businesses. Senate Committee on Rules appointee representing county governments. Governor's appointee representing the utilities industry >> here. Good afternoon. >> Secretary of Transportation. >> Giles Javonazi representing Secretary Tesaken. >> Chancellor of the California State University. President of the University of California. We have a quorum. Thank you. Director Thomas Jacobs is joining us virtually this afternoon. Director, if you're ready, would you like to provide any opening remarks? >> Yes, thank you. I really appreciate it. So, uh, good afternoon everyone. Apologies that I can't be there with you today in person. Um,

004had some conflicts, but really appreciate getting the chance to um, welcome you guys, those of you that are in person at the NPR and in introduce myself. So, I'm the new director of Callowas, appointed just about a couple months ago now. Um, and you know, really excited to be able to be back here at Callaways. Just to offer a little bit about my background so you know where I'm coming from. Um, started in the private private sector down in Silicon Valley first in my in the beginning part of my career. Um, but ultimately knew I wanted to work uh in the public sector serving my community. So, transitioned into emergency management at the local level. uh and then ultimately worked my way up to uh working at Callowas um through the state threat assessment center,

005working with law enforcement, working with the fire service and um uh was here in the 2017 to 2014 to 2019 um during the statewide fires of 2017, the campfire, the Ridgerest earthquake, uh and was overseeing response um at headquarters, the state operations center, a state warning center during that time. Um then I was asked by the governor to stand up a new department for the state uh called energy infrastructure safety which was um created in statute uh after the utility caused wildfires of 2017 and 2018. So I stood up that department for the last six years. Um and then with director Ward's retire retirement the governor asked me to come back to Callowas and and lead Calas. So I'm I'm really excited to be here uh and be back at Callowas. It feels like feels

006like home for me. Um, so I understand that since your last meeting there the there was one big earthquake over in Russia that set off um tsunami warnings. Um, so I know we're going to hear a little bit about that today uh in the in this meeting. Um, I'm not going to be able to stick around for the the full meeting. Unfortunately, I have I do have a direct conflict, but um looking forward to being able to see the the um the briefing materials from the from the meeting. I know you're also going to talk about the um MyShake uh integration into Chrome and Edge and and Brian really appreciate what natural resources is doing to get that up on the the um the browsers across that uh your agency and I know we're really

007trying to push forward to move it across other agencies within the within the uh state family. So really appreciate the support from the other agencies getting that done. Um and then I know there's a panel discussion um from the uh SIS CISn network. Um so really uh looking forward to learning more about that. I know. Also, I have to say I was really excited to get a briefing from my team um on earthquake early warning when I first uh came on because right as I was leaving in 2019 was when um the initial funding for this was um getting allocated and it was the very beginning stage of getting this up and running. And it's really exciting to see how far all of you have taken this over the last six years now with over

008a thousand s um sensors um that are 9 you know looks like 96 um% complete in terms of getting up and running and I know that our partners at Caltech and UC Berkeley and the um the geological survey the USGS um all of our partners across the state family really appreciate all the work you guys have done and it's very impressive. Um, looking forward to supporting you guys, continuing to do more great work and really pushing out the the full benefit of earthquake early warning. Uh, and um, I hope you guys have a a great meeting. >> Thank you, director. Uh, at this time, Chief Deputy Director Bast, would you like to provide any opening remarks? >> Yeah, good afternoon everyone. Thank you very much for the opportunity to be here and thank you all

009for for being here as well. Uh just want to introduce myself again. I'm Ian Bassik. I'm the acting chief deputy director for operations here at Caloes. started with Callowas back in August of 2024 when I was reported uh appointed as the deputy director for response and uh coming uh I came here to this organization after 27 years with the US Coast Guard including my last assignment as the uh commanding officer of the Coastg Guard Air Station right here in uh Sacramento. Um but then uh around the new year I was appointed or uh asked to uh serve in the acting role as the chief deputy director for operations when our former director retired and uh been uh in this role ever since. But I'm excited to be here and excited to learn more about earthquake

010early warning and uh and what this uh you know all the uh support that this board provides. So thank you very much. Thank you, Chief Deputy Director Bastic. Uh, at this time, would any other advisory board members like to make any opening remarks? Okay, we'll move to review and approve the meeting minutes. In the packet received in your email and in the folder in front of you, there's a copy of the meeting minutes from the last meeting, which was held on June 25th, 2025. We will need to approve the meeting minutes from the last meeting as today we have a quorum. So, please take a few minutes to review. Uh, at this time, we also open it up for any public comment. Uh, all comments will be limited to three minutes in length per person.

011If you're joining us online, please leave us a comment in the Q&A section. Circling back to the board. Um, are there any, uh, Chief Deputy Director Bassic, are there any proposed changes for the minutes? >> Uh, no. Thank you. >> And for the board, any proposed changes to the meeting minutes? >> None. I move approval. >> Second. >> All right. And u just before any comments. Okay. All right. Uh, all those so we have a first. I heard a second. All those in favor say I. >> I. I. >> I. >> All right. The eyes have it. Motion passes. The previous meeting minutes are approved. >> With that, we'll transition to uh transition over to recent events. We'll now hear from Todd Becker, tsunami program specialist, who will provide us with an overview of the

012July 2025 magnitude 8.8 8 kamaka event off the Russian Peninsula. All right. We're working. Good afternoon, everybody. Um, thanks. As Derek said, my name is Todd Becker. I'm with the Seismic Hazards branch tsunami program. Appreciate Earthquake Early Warning having me here today to talk about the Kaka event and all of your time. And um to the next slide. Why are we talking about the Kimchka event? So it was the sixth largest earthquake ever recorded in the modern instrumental time. So it was a big one. It got our attention and it activated response activities that day. And this event occurred um this last July on July 29th, 2025. Um so first I wanted to start talking a little bit about tsunami alerts that we've had in the last 16 years in California that have prompted um

013tsunami response. So this slide shows you um the events we've had in about the last 16 years. All of these occurred from large earthquakes generally across the Pacific basin with the exception of the Tonga volcanic eruption in 2022. The Kaka magnitude 8.8 earthquake was the largest earthquake and tsunamogenic event since the magnitude 9 earthquake in Tohoku in 2011. Both those earthquakes produced a tsunami that puts put parts of California into both a tsunami advisory and a tsunami warning alerts. One difference between the 2011 uh Japan Tohoku earthquake and tsunami and the 2025 Kamaka earthquake and tsunami was that tsunami warnings uh issued via tsunami wireless alerts were not yet in place. And I'm going to touch a little bit more about those um wireless alerts and some recent updates that we've had um from that

014through the tsunami warning center. So, getting to the event on July 29th, a little recap. That day at about 4:30 p.m. Pacific time. National Tsunami Warning Center issued tsunami bulletin number one due to a preliminary magnitude 8.0 earthquake off the coast of Kaka, Russia. kind of germaine to this group was um during that time when that magnitude 8 first came up on the CS CISn and the National Tsunami Warning Center. It issued bulletin number one. I was duty officer that day and I was tracking a magnitude 5.3 earthquake that had just occurred off the coast. Issued a shake alert. I was looking for some myshake numbers, potentially preparing a report that I was going to push out to leadership here. when the screen starts flashing that magnitude 8 and I mean that got all of

015our attention at that point. Uh but that first bulletin um put us into um just noted that that magnitude 8 had occurred. They were evaluating and and California was under evaluation but it definitely got our attention. We were looking at some of the feeds from the National Assami Warning Center. We were on the phone with them and they were indicating that this event definitely was probably going to ramp up as the magnitude got evaluated um and then went up. So about an hour later we went into a tsunami watch alert level for California. About an hour after that, so 2 hours after the earthquake, all parts of California went into a tsunami advisory alert level. And about 2 hours after that, parts of California went into a tsunami warning alert. And that was from Cape

016Mendescino at the Humble County Menescino border to the California Oregon border. And so part of what um caused those alerts to get elevated throughout the event was that it first came in as a magnitude 8 when the National Tsunami Warning Center. They usually try to push out that first alert within that first 5 minutes, but that earthquake is still rupturing. So they're evaluating. And then that went up to the 87, which is what put us into the tsunami watch. and then additional evaluation eventually that magnitude was um revised to an 8.8. And just as a little review, if you're not familiar, um the tsunami alert levels, a watch means that you know a large earthquake potentially tsunami tsunamienic event has occurred. The Nationals Tsunami Warning Center is still evaluating, but it's that time when we

017get that that we're going to start taking actions, start spinning up response activities and getting everybody going. When we go into an advisory, that's when they've um done their modeling and have some data to estimate that tsunami wave heights are bound to be between 1 to 3 feet. And a tsunami warning is when tsunami waves are anticipated to be greater than 3 feet. >> All right. And this slide is just showing a bit of the timeline, the tsunami travel timeline for that tsunami that day. And as you'll see there, um, what I was just talking, it took us about an hour, that hour point to get into that first tsunami watch. Two hours to get into that tsunami advisory, and then by 4 hours we're into that tsunami warning. Um, and that night we were

018expecting tsunami waves to the first waves to impact Delnor County a little bit before midnight. And then by about 1:15, a little after 1:00 am that night or early that next morning in San Diego. So by the time California went into a warning um advisory or warning alert level, you know, we were the way was already about halfway across the Pacific towards us, but we were well into our response activities both here in Callowas and with our coastal partners at that time. So now quickly I just want to give a few examples of the bulletins that came in. This was bulletin one. I don't know if it's it's hard to see that, but this was the first bulletin that came in from the National Somi Warning Center at 4:35. So just 5 minutes after that

019earthquake when they do their first evaluation. And some of the things we're looking at, we're looking for what's that information for California. Um, and there I have circled in the red, it was showing they know there was a big earthquake, but they're still evaluating what the potential threat for California is. But it's at that point that um, we're getting ready. We're waiting for that next bulletin to see what our next actions are going to be. And then bulletin 2 came in. Like I said, that was about an about an hour later. And that's when we went into the tsunami watch. And at this point, we're getting some um tsunami arrival time estimations for California. But it was at that watch point when I was on the phone with our duty manager that day, that happened

020to be Derek, telling him that right, we've talked to the National Tsunami Warning Center. We've talked to our partners with California Geological Survey, and this is the real deal. We need to start spinning up our activities. We need to get our coastal partners spun up uh because we're going to have some response activities and potentially, you know, damaging waves due to this earthquake. And then bulletin 3 came out um later that evening about 2 hours after the earthquake and that's when all parts of California went into a tsunami advisory. And so, as I mentioned earlier with the tsunami advisory, that's when we were expecting, you know, tsunami wave heights, you know, somewhere greater than one foot and up to three foot for many parts of California, which, you know, could be damaging and hazardous to

021people and property. And then later that evening, we went into tsunami bulletin number five. And that's when parts of California went into a tsunami warning. Um and that's the tsunami warning was from the coast of Cape Menescino. So the Cal or the Mendescino Humble County border north to the Oregon border. So essentially Humble County and Delnor County. One thing of note with the tsunami uh warnings is that that is issues a tsunami wireless alert that's triggered by the National Tsunami Warning Center in Palmer, Alaska. And that goes out to um all all phones within a county. So So any of those coastal locations that are going to be within that tsunami warning due to some limitations with their system, that tsunami wireless alert goes out through all those counties. And so it gets a lot

022of attention. There were some issu previous issues with some of the warning in those wireless emergency alerts. And that's something I'll um wrap up today with touching on some changes that have occurred to those wireless emergency alerts since this event. Um and then also the December 5th, 2024 uh tsunami warning due to the magnitude 7.1 that occurred off the coast of California. All right. And then later that night, it took us about um you know to bulletin 14 and um number 35 to where the tsunami alert cancellations started to come in for California. The cancellations first started coming in about 5:00 a.m. on July 30th. So that next day and ran all the way through to about 7 a.m. on July 31st. One thing of note with the tsunami alert levels, a cancellation does not

023mean the all clear. That just means that tsunami wave levels are now below that minimum threshold of uh 1 ft that the national tsunami warning center is monitoring and that the allclear is assessed and communicated at the local level. So that's something as the state we have our state coordination calls with our locals. We're we're making sure to communicate that they know that um before people can return to evacuated areas or before waterways are deemed safe, um there needs to be boots on the ground and people assessing that situation. All right, so a little bit about the tsunami response just to tie this all together. Um the numbers for that day, there were 39 hours of response activities. There were 35 National Tsunami Warning Center bulletins that were sent out about every hour from the

024National Tsunami Warning Center in Palmer, Alaska. There were 23 National Tsunami Warning Center conference calls that happened about every hour during that event time once they got started. We had 20 California State Coordination calls that typically follow a half hour after those National Tsunami Warning Center calls. Um, and the big underlying thing that I've got in bold and underlined here, there were no casualties in California. And it's one of those things I want to keep highlighting. We take it as a win um due to a lot of the efforts here at Callowas at the federal level with our all of our various state, local, tribal um partners at all the work. Uh there were hazardous conditions that existed that day and due to the alerting, the education and the response activities, people were kept out

025of harm's way. Unfortunately, we had no casualties. So, we don't have to hear me talk anymore. I've got a couple videos just to show some of the videos that were captured from the tsunami event. So, on the right hand side, you'll see this video was captured right near the earthquake epicenter in Kamchatka. Eventually, we'll see. I know for some of you dog lovers out there, Megan, there's going to be a cute dog coming up. He got pretty close to that wave. But, as you can see, that runup came really significantly high. I forget, you know, they were saying, I mean, that 60ft vertical splash. So, that um that person was over 60 feet up that that hill slope there when those waves were coming in. And another local video. This just shows an area that

026was inundated near the earthquake epicenter in Kamchatka. I think this video kind of does a good demonstration of how um you know those tsunami waves have come in and that it is a surge. It's not you know your lapping wind waves. You know there's a lot of area that's inundated and then you'll see that you know those tsunami waves are continuing just to be to push in. India, that whole ocean level has changed and that water is just surging in and it's definitely more of like a flooding of land as opposed to a typical wind wave. And then bringing it back to something more local, this is Crescent City up in Delnor County. Crescent City, as many of you may know, tends to be, you know, sometimes it's been termed the tsunami magnet. Um, due

027to the bethimemetry and just its, you know, orientation with the coast, um, it tends to be our most impacted spot in California and has been historically. Um, through time, this wave, you'll see in this video, I think there's some sparking that shows up in the background. And I've got a still image of the that dock that was damaged during that. One of the successes I guess with this tsunami and that damage was that during the 2011 To<unk>hoku earthquake and tsunami, this harbor was significantly damaged. There was a lot of mitigation work that was done and some of the work that was done to the dock that got damaged during this tsunami. And I'll bring that one up. This guy here, um, it was constructed to take a lot of the brunt of those tsunami forces.

028and um the wave or the tsunami wave velocity coming into the harbor that day. So, there still was damage to that dock, but it was kind of the sacrificial dock that allowed the other docks to remain um undamaged. And again, just another video of some of the um really extreme currents coming into the Crescent City Harbor that day. And with that, um, this slide's probably hard to read for some of you, but this just shows, um, for that tsunami event, some of the largest observations for the tsunami waves were in California for this event. Crescent City Harbor at that 1.18 m, so just around 4 feet. Um, there was a couple other locations that were um, you know, also high in California. And so, um, it definitely was a significant event. And like I said,

029um, some of, you know, what went well. Again, no casualties. We really want to, you know, underscore that. You know, we say exercise, exercise, exercise. Just yesterday, we were exercising with the Nationals Warning Center, our seismic hazards branch, our California Geological Survey partners, um, and other folks at Callowas and throughout, um, the Pacific Basin to practice for these tsunami events so that we're ready when they happen. Our coordination calls went well. At the local level, you know, the um again the the education, the training, the exercises with our locals, what they do at the local level, evacuations and waterfront closures went well and got people out of harm's way, which led to those no casualties. Some things we learned to test systems. There were some systems that day that didn't work as expected. we were

030able to pivot and still get beyond, but now we put some things into place um to make sure that we test those more opt often because fortunately the tsunami events do tend to be um far and few between and we hope they stay that way. And so the last slide I wanted to um wrap up with was the tsunami wireless emergency alert update. I mentioned that when a tsunami warning is issued for a coastal location, the entire coastal county adjacent to that will get the wireless emergency alert. Something we found during the Kamchatka event and then also the Kate Mendesino event from 2024 was that the tsunami wireless emergency alert language um had some wording in it that caused concern for people well out the tsunami well outside of the tsunami hazard zone. So both,

031you know, in California and many of our partners through the National Tsunami Hazard Mitigation Program, which includes all the states and territories and science partners um from areas with tsunami hazard have worked with the National Weather Service and Noah to update u that tsunami wireless emergency alert language. And so just in March 2026, they were able to update that that language. So now if a tsunami wireless alert goes out, it's a little bit more direct um for those people that are in the tsunami hazard zone versus the people that are outside the tsunami hazard zone. And we continue to work with them so that it's there will be a point in time that the technology will allow them and the system to alert just those that are in the zone. But um we consider this

032a win and it was a good partnership and something that came out of these events that like most these events we you know assess what went well and what didn't and what we can fix before the next one. And so with that I will wrap up my overview of the Kamchatka tsunami and I think we've got some time for questions. >> Thank you Todd. Uh chief deputy director would you like to provide any comments? Yeah, thank you. Great presentation, Todd. Appreciate that. And uh thank you for your team's work that that you put in on uh updating those uh alert that alerting language. I know that's really big for our local communities up in California. Appreciate that. >> Thank you. >> And do any board members wish to provide a comment or ask a question?

033>> Uh thanks Derek. Uh great presentation, great to see the progress. Uh two questions. One is just noticing that when the earthquake emanates, you know, by and large from a foreign country, do you get the data? Do you sense it independently as either California or the United States government or do you rely on getting the data from a foreign country? >> So, that's a good question. I'm not sure and I may lean on if there's some people in here that are a little more experienced with that. It does come through our California Integrated Seismic Network and the National Tsunami Warning Center is analyzing that data and so we're getting it directly through that. But as far as I guess sensor networks in those foreign countries, I'm not super familiar with how that works. But >>

034okay, so by and large we're sensing it with American, if you will, instrumentation, not >> do we have CGS or USGS? Um because we get our information, we meaning California, we're getting our information from USGS. Um the question is where are they getting it from? >> If any of our CISM partners wish to comment that that podium is is hot. Thank you. >> Not that I don't trust the Russians, but >> I I'm Alan Husker from Caltech. The answer is both. We have we sense it on all of our networks here in California. But the wave does take some time to arrive here. The seismic wave the fastest way is actually with the our uh yes other countries is where you get the data and there's worldwide global networks that are constantly sharing data and

035the USGS actually um is measuring our earthquakes all around the world all the time. Uh and so that's where the initial data actually comes from. If we waited for the wave the seismic wave to come all the way here before there was a tsunami warning issued, it would take longer. And so you get the closer countries. So countries like Japan, Korea, uh you know, Russia too probably share some, but really Japan and Korea would be the ones that I think are sharing more data uh in that region uh than the Russian ones. >> And I one more you will. Uh so for the one last summer, it looked like the predictions for the wave height hitting the west coast, the US were more or less uh accurate from the earliest forecasts that were put out

036and then what we actually measured here. Is that generally true that we were kind of in the ballpark with like a several hours in advance forecast of wave height on the west coast? It was, you know, within 10 15% or so, give or take. >> Yeah. Yeah, the um the estimates in their model, their modeling is pretty good. And I think once they have that, you know, that that rupture model, you know, what that rupture was and um the first data that's hitting those dart boies, those deep ocean buoys, their modeling's pretty accurate. Yeah. And it was, you know, it was pretty spot-on to what we ended up with in the end. And also one of the things we get in those alerts duration. We were just talking about this yesterday and that's one of

037the things kind of you know posttop I was looking at was the duration and early on in that it estimated Crescent City was going to have a 36-hour duration for that. I mean it was almost to the minute that you know we had 36 hours that those waves were bouncing around in Crescent City whereas other parts you know was 10 to 12 hours. So their modeling yeah was pretty spot-on for this event. And one of the reasons why I was inspired to ask that question is that the the event in December of 2024, which was off Menescino or Fort Bragg or somewhere, >> I think that one, if I remember correctly, may have been underwhelming when it finally hit in terms of >> I mean, there were there were some pretty dramatic wave heights early

038on and we all scrambled, especially those in the Bay Area. Um, and then, you know, we saw like a couple inches of wave height hit the Golden Gate or something. >> Yeah. the so the local and regional source events are I mean there's they're kind of our Achilles heel both from a time for response and also their time for evaluation and some of that like that why national tsunami warning center put us into tsunami warning alerts from the Oregon border to the San Francisco Bay area is just a matter of protocol and it's because that earthquake was over a certain threshold that they are not going to be able to get enough data or get any data before those tsunami waves are impacting the shores. So they just have to push out those alerts. And

039recently I was just looking at one of there was a earthquake in about a similar magnitude off the coast of Indonesia that there was about a twoft wave that you know hit the hit the local shores there and it was kind of you know a little bit um reinforced why the National Tsunami Warning Center does what they do in those events. But unfortunately some of those you know in those circumstances it does right it is kind of on the the overing but it's the where we need to lean on the side of caution for those events because it's that one out of 10 times that we're going to get that underwater landslide or some event that's going to cause a damaging tsunami that they have to push out those alerts and and that's something post

040those events we've worked a lot with the local communities to um have follow-on messaging for that because that's something else we have to balance after events like that is the public perception and just communicating what the hazard is and why why the alerts went out as they did. Um, yes. Uh, board member Cash, >> I was just wondering, I know we have sensors all throughout California for earthquakes. Did you mentioned there were deep ocean buoys? I was trying to figure out how you calculate what the size of the waves are going to be that that hit California. It sounds like we were extremely accurate, so bravo on that. But just trying to figure out how we actually do that. Do we have >> Right. This is This is where I am. Wish I had Jay

041in the room. Jay like uh so Jay our California Geological Survey partners and uh you know Jay can give you a great overview of that but I can give you a simplified one. So the Nationals Tsunami Warning Center they're the ones that are monitoring for this. They're operating you know 24/7 365 looking at those waveforms coming in from the different networks and monitoring that buoy network. They also have, I think, two different modeling systems that when they've detected an earthquake and then they're waiting for some of this these data to hit these buoys based on the data that comes into those buoys based on this premputed data they run those through the system they get these two different model results. I think there's a averaging or you know mean between the two models and then

042that's what they push out but those models are based on you know a lot of right just I think you know both theoretical and you know observations from you know historic events and you know recent events so that they can kind of you know get a get a pretty close approximation and they're constantly refining all of that >> and and board member cash that falls squarely in our TGS partners uh realm and what we can do is follow up with you with a an even more accurate definition and thank you Todd for taking that on. >> All right. Uh any other questions or comments from the board? And now we'll turn to actually we'll we'll now turn to uh Philip Labra, the earthquake early warning system operations manager uh to provide an update on recent

043seismic events and program updates. Um, but before Phil begins, would like to acknowledge for recording purposes, voting member Julie Sulier, designign on behalf of California Health and Human Services, join the meeting at 1:24 p.m. Thank you and welcome. Okay. Thank you, Derek, and good afternoon, everyone. Oh, uh, I'd like to highlight recent earthquake activity around the state that has garnered significant media attention since our last meeting. In response to the seismic activity in India, San Ramon and Boulder Creek, our program in coordination with the Caloes crisis communications team have implemented targeted messaging to the affected areas through rapid response efforts. Once an earthquake occurs, the earthquake early warning program identifies a targeted area to send ready to go preparedness messaging for the impacted communities. This is typically done through media inquiries, interviews, calls, and social

044media. In addition, public safety messaging is displayed on Callowas's various platforms, including callos.ca.gov, earthquake.ca.gov, and uh social media accounts. This strategy helps to uh get messaging out quickly uh to those affected areas and brings awareness to those outside of the directly impacted areas to take proactive steps to be prepared in the event of an emergency in their areas such as aftershocks. What you see here, California has experienced uh several earthquakes since the start of the year. A magnitude 4.9 earthquake struck near Indo, California on January 19th and was part of a notable sequence in the Coachella Valley. The epicenter was approximately 12 miles uh from Indo in the hills near the southern San Andreas fault and shaking was felt throughout the greater Los Angeles area and as far down as San Diego. Uh according to

045about 8,200 USGS felt reports, this event was the main shock of a very active sequence. Uh I think over 800 events were recorded in the following weeks and the activity occurred in a complex region where the San Andreas and the San Yasento fault systems interact um known for seismic swarms. Uh there were no reports of significant damage or impacts um because the earthquake was estimated above that 4.5 magnitude 4.5 threshold. An earthquake earlier warning alert was distributed for this event. As you can see nearly 59,000 myshake alerts were sent to devices in these areas and Google delivered over 470,000 uh alerts sent to uh Android devices. After review, the system performed as designed and expected uh providing several seconds of warning to residents. Over 86% of devices received the alerts for my shake with some

046arriving 10 to 20 seconds before feeling shaking. I did want to highlight that the shake alert system issued the first alert in 6.5 seconds and then the myshake app uh took 0.3 seconds uh to deliver the alert to the first devices. Uh this slide represents a daily overview of the MYSH downloads. During the Indio event, uh we observed that downloads usually tend to to surge up following an event uh and can stay elevated uh for several days afterwards. So in just 5 days, we saw that myshake was downloaded over 18,000 times. Moving on to the next event, a few weeks later, uh a magnitude 4.2 2 earthquake occurred near San Ramon on February 2nd. Uh an event that shook the San Francisco Bay area. The activity was located within the Calvarious fault system and that

047magnitude 4.2 was part of an earthquake swarm. Uh sequence of quakes without a signal clear main shock on February 2nd alone. Uh dozens of tremors were recorded that day. Shaking again was felt widely across the Bay Area with over 5,000 felt reports submitted to USGS. reports came in from as far north as uh Santa Rosa and as far south as Santa Cruz. Again, no major structural damage or injuries were reported and local impacts were limited to items falling of shells in the San Ramon and Dublin areas because the earthquake magnitude was below the magnitude 4.5 uh alerting threshold. Uh no EW alerts were sent out via MyShake or on Android devices. And then as you can see over the span of five days uh my shake had uh recorded more than or we we saw

048more than 10,000 downloads for my shake. On April 2nd, a magnitude 4.6 earthquake um struck just 2 kilometers souththeast of Boulder Creek, California. That's located north of Santa Cruz. This seismic event took place within the Santa Cruz Mountains which is which is part of the San Andreas uh fault system. The USGS recorded a peak shaking intensity of mag uh of an MMI6 which is strong shaking near the epicenter. Over 33,000 felt reports uh to the were report were recorded by USGS indicating that shaking was felt as far north as Pedaluma and then as far south as King City. Uh for this event over 400,000 my shake uh alerts were sent to devices and Google delivered over 1.2 million alerts to Android devices because the initial automated estimate was above a magnitude 5. A shake alert

049was issued within 4.9 uh seconds. My shake then took 2.1 seconds to send alerts to the first devices and over 92% of these devices that received alerts uh just a few seconds before people began to feel uh the shaking. Again, we do have a table with the MyShake downloads for the Boulder Creek event. Uh in over 5 days, my shake had downloaded was downloaded over 23,000 times. Again, these events um serve as a real-time assessment of the system. In addition, our rapid response efforts also provide an opportunity to remind residents and visitors that we do live in earthquake country, underscoring the need for everyone to stay prepared. Now, one of the key outcomes from these events um has been the increase in public engagement and awareness surrounding earthquake preparedness, especially through tools like the MyShake

050app. Since its launch in 2019, the MyShake app has nearly uh 4.5 million downloads and sent more than 6.1 million EW alerts. Recently, the Berkeley Seism Seismological Lab with support from Caloes has broadened the reach of MyShake beyond mobile devices by introducing a browser extension. This functions on laptops via Google Chrome and Microsoft Edge. This this enhancement offers uh users another way to receive earthquake early warning alerts on devices that they manage. With this new feature uh in place, we begin to uh to expand and implement the browser extension across various state agencies. To facilitate this rollout, Callowas has created a comprehensive deployment toolkit that includes staff messaging, IT setup instructions, uh FAQs, feedback mechanisms, and guidance for using Google Chrome extensions. So far um thanks to CGS and building CAS and CGS have adopted

051the toolkit approach and rolled out the browser extension across both agencies. The initial feedback from CGS uh has been positive. Now the next step um involves sharing the toolkit with additional partner agencies uh across state government for their IT review uh and as well as potential deployment and implementation. So, if you are interested in participating in um this new capability, please reach out to our program um at earthquake [email protected]. >> I think that's it. Back to you, Derek. >> Thank you for those updates, Philip. Uh chief deputy director, would you like to provide any comments? >> Thank you for the presentation, Philip. Uh no comment. Any board members uh that would like to provide comments or questions at this time? All right, hearing none, uh opening it up to the public. Seeing there are no

052comments there, uh we'll now move into the education and outreach portion of our meeting. John Goodell, education outreach lead coordinator, will provide an update on the 2025 Great California Shakeout Tour and additional outreach events the EW team has participated in recently. >> All right, thank you Derek. I am John Goodell and I work alongside Julie Leo and our education outreach program. We've had a busy year promoting earthquake early warning, including media campaigns and outreach events. So, most notably is our annual Great California Shakeout Tour. We travel up and down the state in advance of the Shakeout drill with the primary focus of promoting earthquake preparedness, uh the MyShake app, and ensuring that everyone is prepared for the next big earthquake. Each tour stop includes an earthquake simulator, an outreach booth, and a strong media presence.

053As you can see, that was our tour from last year. We traveled to four different cities, including all new sites to us. The the tour began in the Sacramento region at UC Davis, followed by the San Francisco Zoo, and then our first ever stop in Orange County at the Cal State Fullerton campus. Concluded in San Diego at the Waterfront Park. Generally, we prefer to end the tour in San Diego, and that's due to other high-profile shakeout events already scheduled in Los Angeles and in the Bay Area uh on that Thursday, the day of the shakeout drill. So, what you see here is a snapshot of last year's tour, some of the some of the metrics. So, what stands out the most is we had more than 200 simulator experiences, which means number of people that

054rode the simulator. Uh we did nearly 35 media interviews including live and recorded TV, radio and newspaper in both English and in Spanish. Uh during the tour we had an increase of more than 34,000 downloads of the MyShake app. So roughly about 8,000 new downloads per day of the tour. What you don't see here is we also had 12 uh seismic hazards branch staff in four areas across California. We had more than 10.4 million people register for the shakeout drill in California alone. We had an influencer campaign that went uh on the morning of the shakeout drill. And then this was a all hands-on tour. Our seismic hazards branch was obviously involved along with our public information team and our PR contractor. We all worked in unison to put in uh to put on this

055event. Uh in addition to the shakeout tour, Caloas also jointly coordinates and participates in two events on Shakeout Day. one in Southern California, one in Northern California. At the City of Los Angeles Emergency Operations Center, Earthquake Country Alliance and the City of Los Angeles hosted a press conference that was covered by Los Angeles area media. Callas had Ian Bastic and Nate Ortiz attend that event. In the city of Oakland's Frank Ogawa Plaza, there was significant media presence with a press event, including the mayor's office and Oakland's fire chief. Additionally, live trainings took place, including evacuations, large-scale shelters, and using fire extinguishers to put out active fires. Callowas was represented by Ivon Dontes. At both locations, Callowas hosted outreach booths providing critical earthquake preparedness information including how to secure your space, prepare a go bag, a

056shelter in place kit, and protective measures during an earthquake. And as we look ahead to this year, we already considering cities and sites and discussing logistics, including the three major media markets, Bay Area, Los Angeles, and San Diego, plus Sacramento, maybe more cities this year. Thinking of creative ways to use influencers and start the social media campaign earlier. Possibly adding a shakeout earthquake evacuation drill here at headquarters. As always, a central focus on our efforts is expanding our educational outreach messaging via media outlets and inerson community engagement as far and wide as possible. Regardless of the media market, audience or location, the following message is always consistent. We focus on drop lock and hold on, securing your space, increasing my shake downloads, turning on phone notifications, and preparing an emergency preparedness kit and go bag.

057And last slide here. So lastly, while the Shakeout Tour is our flagship event, we also attended and collaborated on other prestigious events, outreach events throughout the year. Most recently, we attended events in the Bay Area at Meta Headquarters, which is home to Facebook and Instagram, as well as events in Anaheim and Santa Rosa. Uh for META, we had the earthquake simulator and outreach booth. Uh a local search team also participated. The event was designed for META employees only. Uh in Anaheim, we were at the Disney's Grand Californian hotel with an outreach booth shared with the Seismic Safety Commission and that was attended by partners within the infrastructure and building sectors. And in Santa Rosa, which was just a couple weeks ago, um we had the earthquake simulator and outreach booth. This was in recognition of

058April as earthquake preparedness month. The event was the wildfire and earthquake expo at the Sonoma County Fairgrounds. And it was open to the public, which had an estimated attendance of 3,000 people. And in the coming months, we'll be attending fleet weeks throughout the state, more outreach events, and of course, our annual shakeout tour again in October. That's it for education outreach. Thank you very much. >> Thank you, John. Chief Deputy Director, would you like to provide any comments? >> Thank you, John. appreciate uh you and all the team's work on those outreach events. >> Any board members like to provide any comments or questions? Board member breaks, >> just curious how the conversation went with Instagram and uh Facebook. Were they interested in doing it or >> the integration of earthquake early on? >> Yeah.

059In his social media. >> Unfortunately, I was not part of that conversations, but I'll turn over to my >> Well, John is tracking that. That is to be continued. Um, obviously we we have visions of grandeur. We'd love to see uh EEW incorporated with uh streaming and social media services. So, we'll continue to fight that fight. >> There's a certain demographic you'll hit immediately if you uh >> Absolutely. Yes. >> Uh board member Cash. >> Yeah. Did you say that 10 million people signed up for the shakeout? Shakeout drill. Yeah. 10.4 million in California alone. >> Wow. >> Yeah. It's grown to be a worldwide drill. >> That's amazing. That's a quarter of the population of the state. >> Well done. >> And California generally makes up the vast majority of the worldwide um signups

060for the drill. >> All right. and checking to see if we have any >> question. When they sign up, do they sign up through a portal? And is there a way to also have them remind them to download the app? >> so you you sign up for the Shakeout drill, you sign up on shakeout.org. I believe that's the only way to sign up for the the drill itself. >> And then on that page when you sign up, is there a remember to download the app as well? They're they're >> so it's not directly, but Earthquake Country Alliance is a partner of the program and so you'll see them at events pushing the My Shake app just as much as Shakeout. >> Okay. >> Thank you. >> Okay, checking again to see if there's any public

061comment. All right, with that, we'll now move into research and development portion of our meeting. Uh, our R&D lead, Brandon Howland, will start with status updates on recent research and implementation projects we've previously presented to the board. Good afternoon everyone. Thank you so much for joining us here on this day to talk about, you know, all our projects we're doing. And so I am Brandon Howland, the research and development lead. So, I have the great job of kind of figuring out how we're going to spend our money. Um, so it's quite fun for me and a great obviously it's a group effort, but um I get to pitch ideas and so forth. So, today I'm talk about two different projects that are just now concluding and kind of another one starting up and we'll finish

062up with a with a panel with some of our partners. And so last time we had the advisory board, we talked about our earthquake early warning airport feasibility study that has wrapped up and is now live on our website which you can go view. The public can view and and read the entire document. Highly recommend. But then since then and success of that study, we are progressing towards a grant. So we see this the success with from the study the importance of implementing at an airport and so now we want to put some funding to start that. So as we're probably aware airports play a role in disaster response and recovery including emergency relief operations. Earthquakes pose a risk to airports and based on advice from one of our advisory board members, Kelly has partnered

063with UC Berkeley to develop that EW airport feasibility study that I mentioned. Our goal is to implement EW and to airports and we use this study as a guide to showcase that importance to airports and their facilities, which is why we have a grant that is now live that is going to be providing $800,000 to EW implementation at airports. To give to give a bit of context uh from the airport study, California airports have been greatly impacted by earthquakes in the past, meaning large earthquakes disrupted airport operations. In airports affected by earthquakes, you often see one or both types of damages that occur. See structural and non-structural. Structural damage is what we typically think in terms of big earthquake damage, right? We think of the cracking in foundation, collapsed stairs, broken columns, that's not typically

064what actually happens. That's that happens. Or if that does happen, we see non-structural causing the bulk of the damage or the bulk of the injuries. And so that non-structural damage, that's where we see windows shattering, we see ceiling fixtures falling, we see pipes bursting, furniture moving, lighting systems dis uh dislodging. And these non-structural damages can cause serious injuries to people. But most of this damage can be mitigated by drop cover and hold on which is where EW comes in. You also see liquefaction is a major is a serious issue at airports during an earthquake as it can cause significant damage to the facilities and stop operations. This can also compound the effects of the um sorry of the shaking on the system like fuel pipelines. EW has the potential to to help reduce the level

065of fuel loss and help warn operators before shaking occurs to give them time to take protective actions. Now, the researchers of the study performed a benefit cost analysis on many of the common EEW implementation automations that could be seen at an airport. You can see that depending on the size of the airport, as an example, for our study, we have Palm Springs Airport and LAX. You can see depending on the size of the airport, the location and just their facilities, you see much different BCR, benefit cost ratio. Some of which seem as if you know maybe gives kind of an option for the airports. Do I want to pursue the one that provides the highest BCR or see one that maybe it's not quite where you want it to be? But there are actually more

066benefits that can be implemented into this BCR than these researchers were able to actually implement. those variables are really hard to measure such as return to operations which is a huge benefit of EW but not something that researchers were able to quantify in this study. So going to our grant. All right. So we we saw the success from our study. We saw the importance of implementing. So now we have the grant moving $800,000 into funding EW into airports. That grant is split amongst two recipients. And the grant is going to run from June 1st, 2026, so just coming up to March 31st, 2028. So providing almost two years to implement EW at the airports. The awarded grantees are Ontario International Airport as well as John Wayne Airport and the focus of their implementation is on

067PA announcements and visual paging systems being implemented with EEW. You see also they're looking at fire station bay door automation visual paging systems as well as SMS texting um that can be alerting the staff. And so a big part of what they want to push is alerting their operations because as I mentioned before big part of EW is not only making sure people are safe they can drop cover and hold on to protect themselves but also how do we get back to operation status operational status after shaking occurs. So that is our project that kind of concluded with the study and now we're moving forward with the grant and now we're going to move into fire stations. So this project just wrapped up. I'm very happy with how it happened and how it concluded. Sorry.

068So Callowas worked closely with the Callowas fire and rescue branch and the Callowas grants processing team to ensure the success of this project. The fire departments were selected based on pre-identified methodology and criteria. This includes a fire station or multiple within communities with a CDC social vulnerability index or SVI of 0.6 and above. They also have to house a CAS fire asset. And being in a location with a history of catastro history of catastrophic seismic events. For the purpose of the grant, it was important for us when we were um finding fire stations to fund that they have that SVI above 0.6 six to promote diversity, equity, and inclusion. The fire departments selected for the pilot project were Alama County Fire, Los Angeles County Fire, Morango Reservation Fire, Rioell Fire, and San Bino County Fire.

069Of the five, only Los Angeles County Fire and Moranga Reservation actually executed the grant. The three others backed out of the funds. Now, the two grant recipients, LA County Fire as well as Moranga Reservation Fire, received up to $167,000 to cover the cost of outfitting the fire stations with EEW technology and equipment as well as five as well as up to five years of operations and maintenance costs. There's no cost match for this grant, which is always a big selling point whenever we tell people about our grants. The grant timeline was June 1st, 2024 to March 31st, 2026. LA County implemented EW at five of their stations and Moranga reservation implemented at their one fire station. We have a quick video. It's rapid succession here, but it's a teaser trailer for footage for our success

070story video, which should be out in the next few months. This shows a rapid response from firefighters as they respond to a call. EW is designed to prepare them and assist them in responding to an earthquake by opening the bay doors upon detecting strong shaking in their area and providing an early warning of the shaking so they can take their own protective actions. This will help protect them from injury and help reduce any delay caused from the shaking. EW protocols that were installed in fire stations may reduce property, quickly restore operations and first responder and as well as provide first responder safety. EW technology could, for example, reduce the potential for hazmat and fire issues as well as improve communications following an earthquake. installed EEW technology can open bay doors, stop elevators, throttle gas valves,

071provide community tornado style siren alerts, SMS text messaging and more. These automations are are now active in these fire stations of LA County and Branga reservation. And a nice side effect of this project and just shows the collaboration of this together is that there's a challenge with implementing EW into fire station bay doors because if you think about okay well shaking occurs bay door opens fire trucks are out who's going to close the doors or say the fire trucks are already out on a call shaking happens doors open well that's just leaving vulnerability to these fire stations. which if you're a firefighter, you don't really want random people, you know, patrolling your uh fire station while you're gone. Well, so through this uh project, Moranga Reservation and their electrician found a way to work around

072this. So, they put a timer on it so that way the doors are only open for two two or so minutes depending on what they wanted, which gives more than enough time as you saw just how quickly firefighters are able to get out. You know, they telling me they can get out oftent times in just mere seconds. So, two doors of the two minutes or so of the doors being open, it closing immediately afterwards. This not only allows for the opening of bay doors so firefighters can get out reducing delays as well as preventing enttrapment of the vehicles which is a major issue and has been seen in a previous earthquake here in California. But then it provides the firefighters with that safety net knowing that their fire station is still secure after the fact.

073And so Morango and their electrician bill is able to find a workaround and then shared that with LA County. So LA County has now implemented that as well on their five fire stations with EW. So I love to see that collaboration between groups. Um it's kind of an added benefit of our project. >> All right. And thank you Brandon. Also want to thank board member Giles Giovanazi and Cala uh as well as uh Derek Caner from Calatrans with uh the support and guidance through both of the airport uh projects that were executed. Um with that uh chief deputy director would you like to provide any comments or questions? >> Thank you Brandon. No no no comments. Appreciate it. I'll >> turn to the board to see if there are any comments or questions. Uh, board

074member Briggs. >> Thanks, Brandon. Um, this this might be a bit unfair, but uh, do you happen to know if airports are built or held to a different building code than, you know, normal commercial or I mean, I know hospitals and nuclear reactors, but I mean, are airports, they have their own code. It's likely enhanced, you know. >> You know, I don't know that. I would imagine there'd be something, but I'm going to turn to our advisory board member to see maybe if he knows. Um, >> we we can look into it and and circle back. >> We'll make note of it. >> Uh, and then, uh, just with respect to the fuel shut off at the airports, uh, I mean, do you think that's going to gather some momentum? It seems like a low

075cost, high benefit item there. >> Fuel shot. So, sorry to which one? >> The fuel shut off at the airports. Oh, yeah. Yeah, I mean there there's as you saw from the numbers is a huge uh BCR. Um, so great benefit and very little cost to that especially I mean part of the project we were able to tour the fuel depot of LAX and it's absolutely remarkable to see how much fuel available to store and move on a daily basis and so getting something that can you know at least limit the amount of fuel being dispersed from strong shaking I think would be absolutely incredible in terms of reducing the risk of fires post earthquake which is a major concern but then also So, you know, getting back to operational status post shaking >> a

076and I would say we were um pleased. I don't know if that's the right word to use uh when we received back the feasibility study and saw that some of these benefit cost ratios were rather considerably high. um supporting what we had anecdotally been saying for years that the mitigation efforts and the earthquake early warning um were of great benefit both for the notification of the general public as well as these automated actions. And um I would say another thing that really pleased us was um or at least me when we went out we thought okay so now we have the feasibility study we have momentum with the airports let's put into place this pilot. Um we actually got two other airports that didn't participate in the feasibility study apply for it. So that kind

077of shows um you know that the outreach and that the industry was um hearing about it and thinking about it. So if you haven't read the report, some of it is is a real easy read and then some of it is, you know, the number square roots of this multiplied by the blah blah blah. Um if you're like me, you'll skim over those parts. But I think uh the message of the report is very easy to understand that this is definitely a benefit to airports and uh so we're really excited about the possibility of maybe more um getting involved. >> All right. Thank you, Deputy Director Nour. If any of the board members are interested in individual briefings uh besides when I've met with you all in the premereings, please let us know and we'd

078be happy to oblige. All right. So, we will uh continue the R&D section at 2:13. Okay. To start the second half of our EEW advisory board meeting, Brandon will be joined by three of our system operations partners for a panel discussion. I think Phil's checking something real quick and then we'll get started. All good. All right. So, thanks again everyone for joining and panelist. Thank you so much for joining us here. I got a few questions for you. Just talking about the projects that we've been working on with EW and some projects that you've been uh focused on in terms of earthquake response and safety. But before we begin, uh I want to kind of introduce you and allow you time to introduce yourselves and your labs and what you do. So first we have

079on our left Hamid Hadari sorry about that from CGS so California Geological Survey Julian Marti from Berkeley Seismology Lab and Alan Husker from California Institute of Technology. Hamid if you want to start first if you want to just give some background from yourself as well as what you do at CGS. >> Sure. Thank you Vir and good afternoon everyone. My name is Hamid Hadadi. I'm a supervising engineering geologist with California Geological Survey. Uh I manage the California strong motion instrumentation program that within the state we also know the program as earthquake engineering program. So um I speak very shortly about the uh the mandates of the program. Uh the main mandates of the program is to instrument uh uh record the strong motion data from the representative uh structures and geological settings in California and

080then interpret the data uh for the data users and provide data uh to the community and the strong motion data users. Uh just quickly about our uh network. Um we have a network of about 10,000 uh sensors uh from instruments installed uh on the ground surface as well as in different types of structures like buildings, bridges, dams and other types of uh structures. And the data that we get uh goes through a project that we call the data utilization project for interpreting data and providing to the public as well as we provide data through the center for engineering strong ocean data that is a joint effort of California Geological Survey and the US Geological Survey. Good afternoon everyone and thank you for your invitation to participate in this panel today. My name is Julia Marty.

081I am manage a team of about 30 researchers and engineers at the Berkeley Seismology Lab. Uh some of our main projects are uh the real time monitoring of earthquakes in Northern California in collaboration with the USGS. Uh earthquake early warning of course we already talked about that. The M shake application I think we're going to talk more about that in this panel. Uh the monitoring of seismic faults in Northern California. Uh the use also of distributed acoustic sensing so D for a broad range of application. And I think we're going to talk about that as well today. Um, and we also operate a network of about 250 seismic and jetic stations all across Northern California. And we uh we also produce uh archive and disseminate a lot of earthquakes products and data to the civil

082engineering and scientific community. Uh quickly about myself. Uh so before that I work for several national and international organizations including more than 10 years for United Nation organization in charge of nuclear test monitoring. Thank you. >> Hello, I'm Alan Husker. Um I work at Caltech or California Institute of Technology. Uh very similar to what Julian just said, uh run the seism network there. Uh, Caltech very much tries to incorporate the um science along with the research or science, excuse me, along with the technology. Uh, so we're always pushing the envelope for new things and trying to um bring in new ideas along with uh the the um these kind of projects with uh the sensor network that California that we're running, the Southern California seismic network that's part of the shake alert um and part

083of California earthquake early warning. Um we have many different projects going on and it's very similar to some many of the things that uh Julian said including uh DAS and then we also pro provide the official magnitudes and locations for earthquakes in the Southern California region. Uh work with many partners um I think Julian covered most everything I wanted to say because it's very similar position. Uh so I'll just leave it at that. >> Right. Well, thanks everyone. So that's our panelist. And so we're going to start kind of going product by project and talking a bit more about it. And then we're going to focus a bit more on what we've done in the past with R&D and kind of where we're looking for in the future. That's kind of the focus here. Uh

084getting started, we're going to start with Hamid and we're look be looking at the um sensor data for engineering engineering applications. And so application of EW stations data in the real-time shaking map that shows the level of ground shaking in real time at each station and can help emergency managers learn where maximum shaking is felt. So for you, this application again uses that real-time data from the ground response stations as well as could be very beneficial in these settings. How much time do you think it'll take to calculate the severity of shaking? So uh the real time shaking map that you mentioned Brandon is a part of uh an application that is called quake map. Uh this application the background of the application is that we started with another application that was called CIS display.

085It was developed at Caltech and then we made a web portal of the CIS and display with some additional features and now we call it quake map. The real time shaking map is one of the features of the quake map. Uh what it does is uh data strong motion data from the real time stations including the early warning stations and any other real time station go to a server uh that the real-time shaking map basically is the interface of of that server. What it does is that uh within uh 1 minute from uh basically in in in one minute uh time intervals uh it uh finds the maximum of shaking at each station and it displays on a map. Uh also it keeps uh the the history of the shaking for 15 minutes and 1

086hour for emergency responders. So what it does is mainly useful for uh very quickly after the earthquakes when we receive the earthquake information from the seismic networks. So by using the real-time shaking map, the emergency responders have the opportunity to to use the earthquake information from the authoritative networks as well as look at the map and see where the re where the maximum shaking is happening. So basically the response time for this application is within uh one minute. But also we are working on a new development that even in in one minute time interval we are putting some uh thresholds that when the big ground acceleration exceeds certain value it would not wait for the entire one minute it shows on the display right away and instantly. So basically that is what the real time

087shaking up does. That's great. And from emergency management perspective, that's something that we would obviously want to see. You know, where is that strong shaking occurring and so if we need to, you know, throw resources in that area, we kind of have a targeted direction and we can see maybe where populations are at and so forth. So having a map like this would be something obviously we would be interested interested in. And you already mentioned it, you know, looking for first responders. Uh do you think this could be something that could be used for both the public and emergency management? uh the map at this time uh is a part of the quake map and is designed for the emergency responders. So basically uh there is a log in uh part of the quake map

088that the emergency responders need to log in to get access to the map. But also we are doing a stress test for this application to see how many users at the same time they can access the map and if the stress test is successfully done and everything works fine it could also be provided to the public but at this time it's mainly uh for the emergency responders. That's great and I know something that we would definitely take advantage of growing in the future and might already be doing so. Uh well, thank you Hamid. We're going to move on to our next project. So appreciate it. Uh moving to Julian looking at the shake table. So this topic is focusing on essentially at a meeting in January 2025 at SSSE meeting. UC Berkeley Seismology Laboratory received

089approval for a 12-month project to utilize to utilize the shake table at UC San Diego to research the MyShake smartphone app and how recent results show these waveforms can be used to extract state of health information and can be used for building health monitoring. Can you tell us the importance of such a project and its implications for earthquake early warning and earthquake response? >> Sure, thank you. Um so uh so this project uh uses in fact my shake um smartphone accelerometer data for uh building health monitoring. So the idea is really to try to establish a baseline of natural frequencies for building all across California and to monitor whether this frequencies they shift or they change uh with time after or after a major events. And so we have managed to identify natural frequencies for

090more than 1,200 high buildings in California using my shake data. So that's a already a very impressive achievement. But in addition to that, we wanted to validate that concept and uh this is what Brendan just mentioned. We worked with the University of California, San Diego because they build uh 10 level building structures on a shake table and they replace some well-known earthquake sequences. And uh during that project that lasted three months, we installed cell phones, smartphones at different level in that building and we monitor in fact that yes using that data we could see shift in frequencies in this building structure one u one earthquake sequence after another. So that's really confirmed that now that we have this database of natural frequencies of building in California, if there would be a major earthquakes, we'll be

091able to monitor those frequencies again and potentially identify if there were changes in those frequency that could indicate that there was a change in the dynamic properties of the of the building. Uh so in term of earthquake response I think this is this is what we would do provide that information to the engineering community and that would allow to flag uh building we know that when there is a major earthquakes for example if we take the example of the enchorage earthquakes in 2018 they had about 10 inspectors they had to inspect thousands of buildings so and they can only go of course one building after another and so the idea is that we would be able to flag the buildings things that most likely had change in their dynamic properties and then those building and

092maybe the the inspector could prioritize the inspection of of these buildings. So that's that's how yeah that's how we think the this data could be used for after earthquake crisis >> and that's great because I know for example from my own experience one of my uh best friends he's engineer structural engineer so he got SAP certified so during a post earthquake he can go and help evaluate buildings but having something like this can help them in that pursuit of figuring out how b how to triage the buildings right which ones can we see already before even out there which should go to first and so that's going to help a lot in terms of our response figuring out who needs to be leaving the buildings immediately um and how do we get back to operational

093status post shaking. >> Yeah. And maybe I should add that CGS is actually really the reference institution monitoring building in in California and they they have very high resolution instrumentation. They do I mean they do this work in in much more details for the building they monitor. But I think that what my share can do is do this monitoring across many more buildings and extend to thousands of buildings in California. And so that's uh that's that's what we can bring to to this project. And I think at Calas you're also training I think you have this safety assessment uh protocol training when you train >> uh staff I mentioned. >> Yes. Yeah. Exactly. Where you're training a responder also to assess the the safety of the building after a major response. That's additional tools and

094that's something I want to bring up next is something like this that you have. I know it's you having phones being able to detect this but I kind of think of you know having more data to kind of add to your algorithm or or different sources. Is there anything like you mentioned the high resolution sensors? Can you kind of combine those together to make even like a not the most scientific person but better product in a way if that collaboration was there? >> Yeah. I mean you want to >> No, I mean it can be either of us. Yes, of course. I think that's I mean first of all I want to say that as you mentioned this was a research project funded by the seismic safety commissions. I mean CGS has been doing that

095for for decades. So I think now maybe the next step will be to think how we can maybe yeah join this data together to make it available to the engineering community so they can make a decision on this on this entire data set. for us. I think what would be also interesting is again we we now have information about frequencies for thousands of buildings but we don't know what these building are. So I think a next step that would be interesting for us is to get more information about each of these specific buildings so we can make our algorithm even better and potentially also look into this inspector reports this I think ATC20 reports to see if we can correlate the information there with those shifts in natural frequencies that that we might observe. Well,

096just add to what Julian mentioned. >> Sorry, Hamid. Just uh before you continue, I just want to make sure the board is aware. You are free to jump in anytime if you have a question or a comment. Sorry. >> Yeah, just I wanted to add that the my shake application that Julia mentioned and what we do in California geological survey actually these two complement each other. Uh what does it mean? uh what we do in CGS we uh cherrypick uh specific type of structures and uh geological settings and we study the response of the structures that could be representative of a large group of uh structures. uh and then we use very high resolution instruments uh uh for the study and interpretation and the results could be applied to uh u many structures in that

097category. Um also the data from uh the CGS stations are used in design of a structures like when we record waveform at a type of a structure uh engineers use the waveforms for design of different structures in the same uh category and in the long term the data from the uh CGS stations are used for uh improving and modifying ifying the seismic design code. For these purposes, the type of data that we use need to be very high resolution data and very accurate data. Parallel to this what Julian mentioned is basically using data at um thousands of buildings and the purpose of that is not for using the data for designing a structure but to say that particular structure if that particular structure responded good or bad to to an earthquake. So that is basically

098the difference. These two do not conflict each other. They complement each other. Thank you. >> Like you know our board member sectors. Oh, we had a question from board member. >> Yeah, just real quick. I just want to make sure I understood. Um the data that you use to measure the frequency response in a building over time and if it's changing it might indicate that there's some kind of structural defect in the building somewhere. Is that coming from individuals with phones? Like and you're getting I mean where where are you getting the data from for a building? Is it is it outfitted with accelerometers or is it people's people's phones? I mean I can Okay. So it's both. So you want to start with the the instrumentation in the buildings? >> Sure. I can I

099can take the instrumentation of buildings. Basically the uh buildings that we instrument in CGS. Uh we use the high resolution uh uh instruments from the seismic equip equipment manufacturers. But I think the part that Julian is talking about is cell phones that uh individuals use in the buildings. >> Yes, exactly. So if the users agree, we can also collect from time to time accelerometer data from their from their cell phone and then we get that data through the myshake application. >> That's that's fascinating. >> Yeah. >> And and to be clear, those are phones that have downloaded the myshake app. >> Yes. And that what allows for such a broad coverage of of buildings. And so I'm thinking like obviously with David Briggs, right, with utilities or with airports, hospitals, uh you know, skyrises for

100businesses, whatever it might be, you know, incorporating this can help with a response setting, right? You have strong shaking and you can see are those buildings damaged. you can use the high resolution sensors to kind of figure out you know the better infrastructure meat and bones of that building to help improve uh later designs and so forth. >> Yeah. Maybe uh giving one example of the high resolution data that we use. Uh there is a bridge in Ferndale area that uh we are working with the department of transportation CLR on that bridge and the plan is to put two seismic gates at each size of the bridge. uh when the when there is an earthquake and the level of shaking gets to a set threshold of acceleration the instrument send a signal to a calr

101device and that device already is using a logic to decide if the seismic g gates should be closed or not. So that is one of the examples of using such seismic data for engineering applications. I have a question for Julian. So theoretically, let's say there's a high-rise downtown, maybe 15 floors, and there's MyShake app um holders on every floor. We have an earthquake. could um the data potentially like literally show where in the building the damage may be. So for instance, if you get it from, you know, 100 or so phones spread about all 15 floors, could you say, uhoh, looks like the greatest resonance difference is on between floor seven and eight or you know, something like that. uh that could be but we will need to know the the the dimension and I

102mean this building very well and we will need to know also where the phones are in the building where which we know like plus or minus usually two levels. So right now the problem is I mean there's no problem but the data we collected from all these buildings usually we don't know we know nothing about those buildings but as I said that could be the next step where then if we learn about that buildings and then if we start looking especially in the I mean the the height of the phones in the building that maybe we could derive a little bit more information about the structure of this building but right now I mean it was just as I said a one-year research project so we mainly look at the the the the natural frequency

103of the building which is usually usually between 0.1 and 1 second and that's the main parameter that we have been monitoring but I think yes that could be really a next step in the project and then we'll do something a little bit more in the direction of what am I described where we really instrument the entire building >> well thank you yeah so I think we're going to continue onwards I think that's great conversation I mean I'd like to see that as you talk about you know past projects and future projects seems like a great chance for collaboration and excelling that project forward. Uh, but we're going to move over to distributed acoustic sensing. So, this is more of a question for Al Husker and Julian Marty, but Hamid, if you have anything to add,

104feel free to jump in. All right. So, there been significant improvements in the effectiveness of reporting earthquakes with introduction of DA cables. And so, I guess before I begin, we should talk a little bit about the the background of of DAS a little bit. Do one of you want to kind of explain a little bit of what DAS is? Sure, I'll take this. So, it's basically turning fiber optic cables into uh seismic sensors. So, um in fiberoptic cables, it's uh light pulses are sending sent down. So, laser light pulses, the speed of light is constant in a cable. So, if it stretches at all, then the time for that laser to go through that cable changes uh the time it takes to go through that because the distance has changed. And so you measure all

105these little wiggles all over the place basically and you get the um all the the full waveform of the seismic waves as it passing across this cable. And so that can be over um 100 miles roughly um that you give these really long cables that are stretched all over the state. Um and so that's the basic uh concept of the technology. And what's exciting not only onshore like with middle of mile initiative but offshore as well uh where we don't have sensors because they're really expensive to put offshore >> for example. So one of the fiber optic cables maybe number isn't quite known but how many sensors do you kind of get in in one of those cables? >> Yeah so uh like a 100 mile cable will give you over 10,000 sensors the equivalent

106along that cable. So you get a sensor. It you can change where you get them exactly because you tune the light bitly. Um you tune different parameters but um one every 10 meters is a rough one every 5 to 10 meters depending upon how you have it set up. >> How can this be advantageous to earthquake early warning or the Q system in general? >> Yeah. So this is advantageous because it fills holes in the network. Um and it also densifies the network. And then especially like I mentioned offshore uh for example in Southern California there are a lot of uh faults offshore that run up and down the coast. It's been estimated could have a magnitude seven uh between LA and uh San Diego. There was a tsunami um I can't remember the year

107now but um it there's defin well a few different ones but one in 1812 actually um in Santa Barbara and so tsunami sug tsunami possibility as well um from earthquakes as well in the region. So uh it's a way to kind of fill that gap in our in our infrastructure and reduce errors. Actually actually one of the huge huge advantages um when we have errors in location or magnitude uh they're most uh they pretty much always occur where the sensor network is not dense and so that's offshore. Um and then there's some holes on shore as well but um it helps fills those holes and reduces errors. >> Just some background. So majority of like the our mist earthquakes, those are offshore earthquakes, right? >> Yeah. And not only missed, but like literally like the

108the sensor network detects it so quickly. Um not all the data is traveled across all the sensors on shore. And so it it first of all the the the seismic wave has takes time to travel onshore. So you're missing that warning time that you would have gotten if you were able to detect it while it was offshore. Uh and then on top of it, you get other errors. So like the location could is can be wrong oftent times or the magnitude is wrong and so you fix those errors if you get sensors closer to the source. Yes, sorry. Just to because really the main change when you have an earthquake onshore because we have a dense network of seismic station. So it's quite I mean I don't want to say easy but we can triangularize

109basically the location of the event of this earthquake which is on land but in the case of an offshore earthquake. If this is the coast we have the earthquake here. All the station are on the same side. So they all point into the same direction. So it's very difficult to locate where this earthquake is. And so with that as Alen explained because now we have measurement point offshore then we can measure the direction this earthquake is coming from at many different angles and this is why we can locate it much more precisely. So we have a few ground sensors and so forth but really not much in the water. So having indust and are working on with offic cables. So the ones you're working with, what faults are they running right now? Uh so we

110have mainly two cables that we have permanent access to. The first one goes uh south of San Francisco right along the San Andreas fault for 50 kilometers and we have again 10,000 measurement point. So now along that fault which to give you a sense before that we had maybe around 10 seismic station around that section of the fault and now we have 10,000 measurement points. So we can really map this fault very precisely when there is an earthquake and the other cable we have is an offshore cable which goes 52 kilometer out of Montter Bay. Uh and so that cable goes in fact around I mean sorry across the San Gregorio fault which is a fault adjant also to the San Andreas fault and which is known to have generated magnitude seven earthquakes or more

111in the past including a magnitude I think 6.4 that was recorded in 1926. So both cables yeah we are really looking at cables that goes either along or across the major seismic fault in northern California. Yeah. And we have so we have a current uh cable that's running data uh that's recording that we've been using for over a year now to measure earthquakes. Um it's just south of Ridgerest and so we were given access because of the Ridgerest earthquake and so it's been running actually for quite a while. Um but it's only been feeding into the USGS like the actual um official locations of earthquakes uh for the a little over a year. Uh so that's running across the Garlock fault um which runs kind of not quite perpendicular but almost perpendicular to the San

112Andreas fault. Um and then we've had access and run data on a number of other different uh uh cables. One of those is in uh Long Valley uh and that was looking at the caldera there uh for what is what we call a volcano uh and looked at the magma chambers. We looked at we also have one that's running through Southern California through LA, the city of LA that we ran for a short time. These are all ones we've ran for a short time and then we have agreements for a couple of cables uh that will run to Catalina Island um and another one that we're working on in the um another part of LA Bay. Uh but the ones that run over uh to Catalina Island go across the Newport Inglewood and the Palace

113Veres faults. Thank you. All right, this sounds better. Thanks, Phil. Uh, so looking ahead a little bit, do you aim to add more cables to be studying DAS? >> Yes. >> Yeah. And and for us in Northern California, I mean, I think even at the scale of California, the area that produced the the earthquake with the largest magnitude is really of Shenesino. So that's really the area where we'd like to secure access to an offshore cable because we have already published papers demonstrating that we could get up to 20 seconds extra warning time. I mean for everybody living in the area also in the in the Bay Area if you would have access to an offshore cable. So yeah that that already with this cable in the Montter Bay bay we show that we have

114this algorithm that process data in real time and then we can get up to six second of extra warming time if we ingest that data into the earthquake early warning system but of course the menesino area is the area with the as I say the largest numbers of high magnitude earthquake in California and that was kind of a question I was going to bring up is are there any critical infrastructure areas or spots like off the capeino that would be the most advantageous to add pass. >> Um, and Brandon, we have a question or a comment. >> Yeah. Quick question just to understand, are these cables that that your teams are are you're having laid specifically for this or or are they utilized for something else and and you're just gaining access to these cables

115for uh for data purposes? >> So, usually it's the second option. I mean there are institution that deploy their own cable that could be one solution of course and that's usually technically the best solution because you can really lay the cable with the shape you would like with the response you would like to monitor seismically a specific area but that means of course a significant investment especially if we talk offshore to lay out that cable. So uh so far we have been using existing cable in the case of the cable which is in the Montter Bay bay. This is a cable owned by Embari the Montter Bay aquarium research institute. We have secure long-term agreement with them and the other cable which is south of the Saint Andreas fold for us. We got access thanks

116to PG&E. So we really like to to thank them for that and they had some unused fiber optic cable going along the Sandreas fault. So it's thanks to them that we can monitor this area. >> Yeah. And just to add, um, you bring up a point that's kind of a challenge. Uh, just getting access to these cables. A lot of what we're doing is working with different people to try to get access. Uh, the middle of the mile in this ship seems really open, but they're very much in like installation phase. They're like, "We'll get to you later." Um, which is fine. Uh, but then offshore it's incredibly challenging. So they're like, "Oh, we'll give you a cheap price for $100,000 a year." Uh and so that's you know that's not something we can afford.

117Um so the it just depends. Um so the where we get we have successes we we put the cable in if or we put the sensor in onto the cable in those places where you know it's a bit more of a challenge we haven't been able to but it's uh we're slowly moving forward I think. So regarding other applications of this that you asked just I wanted to mention about that uh engineers are interested in this because of two factors. One is that uh as Alan mentioned when you use a fiber optics cable you can think of having as many sensors as you need to use. And the second factor is that engineers are very interested in measuring a strain and that is something that does provides directly. I mean uh engineers would like to

118know how the the structures in general the displacement in structures happen and especially for uh high-rise buildings as well as well as any extended linear um structure like a a bridge or a dam or a a railroad. could have a very useful engineering applications. So that is one of the items that I hope that in the future we can explore more and see how we can use that for engineering applications. >> Brandon, >> yes. >> Um I have a question for another use and I apologize I stepped out of the room. You may have already mentioned this. So our first presentation had to do with tsunami and um so can these this same technology pick up tsunami waves? >> Yes. So actually my postto is publishing a paper right now that they use dust offshore

119of Moro Bay to detect the Kamchaka earthquake or we did. So yes, >> thank you. Any questions about D? And we're gonna move along a little bit then to our next project which is looking at my shake. So it's being targeted to Juliana. Uh so my has expanded to laptops through applications for Chromebooks and MacBooks and is now publicly available. It is also accessible in browsers like Chrome and Edge. What sectors do you wish the application to expand into next? >> Yeah, thank you for the question. So yes, we my shake started in 2019 with smartphones and I think as you mentioned now we have close to I mean in the previous presentation we have over 4.4 million downloads for this application and that's really and then we extended yes to Chromebooks and u and

120Mac OS computers. So that's really targeting the public but then we also wanted to target large organizations. So this is why we came up also uh in partnership with you with this Chrome extension or edge extensions because what we learn is that in fact uh IT team in large organization they cannot deploy uh full apps so easily throughout a very large number of devices. I mean it's much easier for IT teams to manage those browser extensions and to roll them roll these browser extensions through all the browsers of the digital devices that are using these organizations. And so this is why we develop a reduced version of the myshake application as a browser extension. We tested it on campus first and then as I think you explained in the presentation before we deployed it at

121cales and then at CGS through thousands of devices at once in fact in in a few minutes. So that's really a great mechanism to bring earthquake early warning into large organizations. But then uh what we have also um observed is that so as I think it was mentioned also in the previous presentation to to increase the number of users from the public I mean users of earthquake early warning those are mainly earthquakes driving the the downloads. So every time there is a big earthquakes we have a high number of downloads but for large organization we don't need to wait for earthquakes like now we just rolled out I mean as as we said the extension in at Cales at CGS and so in the same way uh when we contact this large organization we we

122we realize that sometime we find someone who's very motivated and is going to be excited about earthquake early warning they're going to try to implement something in their organization but then they will leave or they will move to another position and the next person will be less exciting and the project will drop or whatever software has been installed will not be maintained and and that will will not last. So as Mshek what we would like to do now also is to provide a solution to this problem which means that to have a to be able to to to develop also a version of the Mshake application that could be installed in emergency centers, control towers, I mean control I mean basically in a in key area of those organizations and that we would provide the

123information which is needed by by by this organization to take either manual or automated actions and as my shake we will maintain those system or at least the system that that bring the alert into the the organization in order for that to be maintained over time. So that's that's this project that that we plan to start this year in collaboration with you is to build this this kind of backend system that will prioritize the sending of alerts to critical organizations so they can then take manual or automated actions afterwards. And in fact we had two pilot projects uh that were very successful that we did on campus with regard to to to this new system. One of them was with the cal stadium. So they never thought much about earthquake early warning before but we

124brought earthquake early warning into the control room of the stadium and then that started forcing them to think okay now we have this alert. What are we going to do with it? What are we going to announce if we detect an earthquake? So so that's that because we provide a solution for free. they don't have to implement anything on their side or to maintain anything on their side. And the other thing is that we we also have uh our office of emergency management on campus. They manage an app which is called the UC Berkeley safety app. And they also deliver message through text message and emails every time there's a safety concern on campus. And before the person in charge of that had my shake and whenever there was an earthquake alert then he would

125go manually in the system and enter okay there is an earthquake that is affecting the Berkeley campus and that that was pushed by email text and the app of course that was not earthquake early warning anymore and that's by the time the people were receiving the message uh but they reach 80,000 users so that's a big number of users and now basically what we did again we we modify the myshake message we send so they could ingest that message automatically into their system and now basically within a few seconds this earthquake early warning message they get delivered to 80,000 users throughout campus. So I think what we have realized through these two pilot projects is if we want to make progress with having more organizations more uh whether they are private or public I mean

126uh taking this earthquake early warning information and doing something with it. We need to to bring it into their organization for free with some kind of solution that they can ingest very easily. So then they can decide what kind of action they can take next. And this is really in that direction we'd like to to go because as I say for the the public the main driver is earthquakes. I mean the main driver for downloads but we think that for large just with this small project that happened at the beginning of the year we added more than 100,000 users to earthquake early warning is just through the extension or through this UC Berkeley safety app all at once without having to wait for for earthquakes. >> Yeah, it's great. As you saw earlier when Phil

127was presenting he showed after earthquake it was you know how many downloads we had like 10,000 downloads after like in five days. So instead of waiting for an earthling like that you know how can we get into an organization because there's you know something called app fatigue right where you know I don't want a whole another app but maybe this organization already has an app so how can we integrate my shake into the app you already have so we can hit that larger audience >> and I think so and sorry maybe I'm talking too much uh the the other learning experience for us was when we met with our colleagues from Taiwan and I think you also met with them because we realized that they also have an earthquake warning system and they have agreement

128with more than 4,000 organizations and we wanted to understand how they managed to secure so many agreement and one thing is that because they also deliver a solution a free solution for basically this organization to already be able to receive that message visualize that message and then start thinking about what they want to do next with this information and this is why we we also wanted to to to go in the same direction. So the alerting mechanism essentially becomes like a relayed device that basically sends that message to a different organization. >> Exactly. But also try to think about delivering more information for Okay. Two points. The first one is when you push let's say two or three millions alerts. I mean yeah not everybody's going to receive an alert exactly at the same time.

129So we would really prioritize delivering alert to this specific organization and they would be sent right away. So there would be an idea of prioritizing and also probably of delivering additional information. When we deliver the alert on cell phone, we're asking people to drop cover. Hold on. That's it. But then through this extended version of my shake, we could tell them how many seconds they have before they they might they might expect shaking and basically additional information that can help them again making the right decision for their organization at the time. And that brings us to my next question is, you know, moving on from my shake, right? You get the drop cover, hold on. But how do we customize that? How do we customize it to lock cover and hold on? How do we

130customize it to like an operational message if you're sending it to I'm saying surgeons, right? Telling them maybe something specific to their work zone or to people like line workers out in the field. So, you know, maybe we can't change the message on my shake, but through an organizational app that the company uses, maybe it's easier to change that message to help provide that productive action alerting. >> Actually, I think we are thinking about yeah having this this option in the in the next version of my shake. Uh so uh we we are working currently or we just started working on a new version of the myshake application that would be version four and in that version four we'd like to include new features that u that were requested either by your user base or

131that or sponsors or caloras where we think so one of them will be for example having the possibility to to have several home base so you could receive an ali for several locations another one would be for the user to be able to select the message that fit that user. So like for example lock uh cover exactly. So I think yes we have a list of features and our goal is to implement those feature in the next version of the app that we hope could be released next year but of course that also require not only change on the app but also on the backend infrastructure that need to manage those changes. So that's why it's going to be some work before this new version is is released. >> Thank you. And so from there

132I kind of move the question over to the board uh to see if as we kind of talk about my shake and the different projects we've been working here with R&D if you see it benefiting your sector how or even a sector not specific to you but you say oh I think it could help X Y and Z just from my from my perspective uh you know we work really closely with the local communities and the um we call you know our operational areas or or essentially the counties. But I could see where you could similarly apply that uh you know from you know moving my shake through through your university system and getting it out that way to using it where where it connects to their uh their advisory notification system. not their alert

133and warning like uh like they sent out alert and warnings that automatically go out to everybody, but to the signup advisories and getting getting that information that same information out that I think that that would, you know, that works right along in in that aspect. And I think that that's a great, you know, opportunity um and and a great use of that system. >> And I know that some counties have their own app to send out notifications. you know, they're not maybe um early warning alerts, but their notifications, they're kind of alerts in their own way, right? >> Of fires or gas leaks or whatever it might be. >> Exactly. >> Connecting through these county applications can be another way to target a large audience, >> right? >> Anybody else? or thinking of applications outside

134the box here, but have you ever thought about um talking to people who are organizing very large sporting events like the Super Bowl or FIFA World Cup? >> Absolutely. As you may recall, um maybe just as you were coming on, we were suns seting a project with the San Jose quakes where we partnered to do messaging, but the whole goal of that, pun intended. Yeah. Uh was to also uh try to engage them and how it we could potentially integrate earthquake early warning within their building, their facility. uh they're having them recognize their potential position as a location that people may go in the midst of an emergency. Um I don't know if there's any more to add to it, but it's definitely on our minds and we all are aware of the Olympics and

135so uh there's a focus there as well for for the whole team. >> I think one great thing to see is as Julian mentioned, they already implemented my shake into their stadium. So seeing the success there at the uh Berkeley stadium and then how can we apply that to other large venues or other stadiums throughout California. So regarding the stadiums, uh a part of that that relates to instrumenting stadiums, um we are working on a couple of projects right now. Uh one of them is at the Levis stadium that is going to host the FIFA World Cup games in June and uh we are going to instrument the stadium in the next couple of weeks hopefully. that in case there is any shaking we can record and send information out. >> And my team wrote

136a paper about measuring swift quake swift quakes which were created by Taylor Swift when she had a concert in LA. >> Well, thank you. Uh so we're going to come to an end here, but uh moving on to questions back to the panel. This is to any of you who want to answer this. But as the focus of this panel was kind of look at projects the past and how they progressed and then looking forward I want to focus first on the past year. So looking back in the last six to seven years what advancements have we made to cues? So California earthquake early warning. Um have there been any prominent findings that have led to faster alerting or decrease in latency? Kind of open up to the panel to answer that. So cues didn't

137really exist before six to seven years ago. So the existence of it is as a whole as the biggest um thing. Uh but many of the challenges that uh were overcome was the uncertainty the having there wasn't certain at the beginning that it was be possible to have alerts that were issued in a very rapid time. Uh we're moving massive amounts of data. Uh you all are probably familiar with streaming services. uh there's a pause usually before your movie starts. Uh that's because it's buffering. We can't buffer. Um because if we wait and we're buffering, we lose time. And so we have like every second, you know, we're processing data. Uh and so I'm working with more than 500 stations out in the field, 100 samples per second. Um I can just three components on

138all these things. And I can just tell you it's like thousand, you know, I think it was 30,000 streams of data is essentially what we're getting from the field into our data center every second. Um, and so we have to process that and everything. And so that's possible. That was like a big achievement, I'll say. Um, making sure that can work. Um, and then even companies like AWS, Amazon Web Services aren't really even set up to handle this super well because they buffer. They they that's kind of in their algorithms and we can't buffer. we just need to get the data coming in. So we all essentially run small telecoms because that data is all coming in through different cables, fiber, radio, satellite, etc. like whatever it takes. And then once it comes, it goes

139to places like um the myshake app to get the data out actually to people. So it's been that was just a huge achievement I'll say all by itself was making that whole process happen. And maybe to add what to to what Alan just said, I think something that also evolved a lot, I mean since the beginning of cues is really the the algorithms because um after each earthquake there is really a process where we review how performant was the alert, how accurate was the location, how accurate was the magnitude and and so almost every I mean I want to say every time but we really learn about specific scenarios that we could not anticipate before. So with time we have managed to really fine-tune the algorithm to make sure that we will uh we will

140not miss any events to make sure that we'll be very accurate with the location, very accurate with the magnitude even the offshore piece that we just mentioned. We just push a new algorithm in February that allow us to really limit the I mean at least to to do much better with offshore or out of network events. So I think something that's that's really evolved over the last six seven years is how much we have fine-tuned those those those those algorithm that allows to to trigger those earthquake early warning units. So I add to what Alan and Julian mentioned on the engineering side. Uh the early warning project uh has uh had a significant impact on how we look at uh data for engineering applications. Six seven years ago we didn't have any real time data

141center for the strong motion data. We were doing a triggering system at that time. waiting for an earthquake to happen. Shaking starts, get to a level of shaking and then start sending data out. And now we have more than 600 stations operating in real time. And also we have a data acquisition system that receives data from critical structures. And even though these are not uh within the few seconds that the uh early warning data is used, this is very quickly after that. And that is how we use data for engineering applications. A couple of examples is uh uh an earthquake notification system that we put together for Golden Gate Bridge that within seconds now we send notification to the Golden Gate Bridge district when the level of shaking and the two towers of the bridge

142exceed uh certain uh uh level uh in the relative displacement of the basement of the bridge and the top of the bridge. At the same project uh we are uh working with the department of healthc care access and information HKI for a selected number of hospitals to receive data from the real time stations including the early warning stations uh the developing a a very quick earthquake notification sent out to HI for them to decide if any of the hospitals need to be inspected. or they need to take action. All of these happened because of the early warning project. >> Thank you. Yeah, great to see. I mean, think of big earthquakes, right? The 2019 Ridgerest earthquake, we didn't even have EW and that wasn't that many years ago is. So, seeing how much we progressed

143in just a few amount of years is is impressive, I think. So I'm looking forward six to seven years now. Uh I want to see what's your what do you envision for Q's and you can give me both a realistic answer what you think okay this will probably happen and what's your best case optimistic you know gave me that funding I'm doing X Y and Z. >> Uh so on the very immediate term uh we're thinking about and this is still future because it's in progress um the aftershock sequences. So uh everything up till now we always think of the big one you know big earthquake happens we need alert but um aftershock sequence is last or can last and usually if it's a big earthquake we'll have a aftershock sequence that can last for

144weeks months etc. Um, and so what happens in that sequence? And so we we're looking at the LA fires as an example because they use the same uh cell phone alerts, not my shake, but a different one um by the federal government uh to send out alerts during that sequence and that lasted the fires lasted for a couple weeks. Um and what we found is that people switched from uh so this is a paper that we've written um and submitted but with uh social scientists but we found that people switch from think looking at the immediate alerts from the moment and it the hazard as it progresses turns into a bigger thing. So there's the immediate you know fire alerts that are coming out but they're looking at a bigger picture and they want kind

145of the bigger picture and so people switch to the watchd duty app uh which many of you might have heard about. uh similar we project or we think that the same thing will happen after a big earthquake. You know, first they're going to look at these individual alerts that we're getting on my shake and whatnot. Um at a certain point they're going to put the whole hazard together in their head as one thing. Um kind of this is a group of events that's happening over time and you just got to live with it because you know I need to get take my kids to daycare or I don't know whatever go to the bank. I know things are happening and earthquakes are going to happen while you're doing that. You need to drive someplace and

146still do things. And so they're going to switch mentality of kind of like how it works from the immediate danger to like a continued hazard. Um there is not an app that does that right now. Um unless we rely on watch duty and so uh I think that is a a future way that we need to think about uh moving the community just as a suggestion. Um and I think you all can help with that more than probably I can. But um so that's some of the research that we are looking at uh with how people react uh in these and really thinking about um the continued uh aftershock sequence and also then how people react to you know getting alerts. You can get like you know 100 alerts in a day potentially if it's

147a really big earthquake uh somebody's getting 100 alerts on their phone because of all the aftershocks. Is that fatigue or are they going to be like oh this is really helpful cuz I'm freaking out. um you know what what's going to happen there and it's really hard to kind of test some of these situations. Uh so we're thinking about how to test those as well. Um so that's on the human side of things and then further out on these networks like I said improving accuracy and whatnot. Uh we also see multimodal um I already mentioned the fires but um different things these networks can do. So the data is not exclusively only useful for earthquake early warning. Um, we can do different things like look at um how the basin, the LA basin for example,

148focuses earthquakes. So, just like a contact lens, when I was putting my contacts in this morning, you can see how they're concave structure and it focuses the light so it goes into my eye so I can see. Uh the same thing happens with a basin. It focuses the seismic wave energy as it goes up and makes it so places like Los Angeles are much more uh have much more shaking than they would outside of Los Angeles because of that basin focusing. And so when you have DAS and really dense networks, the CSN network for example, we can see how that focusing is working is you get uh bright areas to think of it like where it's really focused and you can see like heavy shaking like after the Whitier earthquake there was a particular spot

149in Whittier that had just extreme shaking compared to places around it. So you'll be able to pick that a lot a lot more with these denser networks that we're that we're getting uh with D and CSN and all these different efforts that we're doing. Um I had one more thing but I can't remember right now but those are the the things. Yeah, I got a question. Yeah, for Allan, um the last thing that you were talking about very interesting because when we had the earthquake up here, um it re the system reacted very differently than um on other earthquakes and at that time and now as I hear you talking, my thought is if we have enough earthquakes across California, couldn't we potentially map them so that we see those areas where we know the

150shaking is going to be stronger and then either adjust our algorithms or our public education in those areas accordingly. >> So people are definitely working on that. It's uh really complicated because um California is all turned up. So it's like it's a big mess which is fun for us to like study as seismologists but like makes it very complicated. But yeah, people are definitely working on that. Um to further complicate, I'll just throw out there. Every earthquake itself, uh you can think of it like a mini sun. Like we get all the frequencies of light that come to us. And so we we can see red, purple, orange, green, etc. Like all these different colors. Um buildings will see different colors essentially because they have they uh will vibrate depending upon what how they're um

151excited. So different frequencies will excite them. And the bigger the earthquake, the bigger buildings tend to get excited. And so you have this there's all the complication of like the size of the earthquake itself will change the parameters of what happens but I'm making this way more complicated than I should. So uh the final thing I was going to say is uh some other exciting things just really outside the box that we can do with this with these technology is measure uh ground groundwater uh and so waves pass more slowly uh through water than they do through uh just completely dry land. Uh and so uh that's one of the things that looking at basins and aquifers is uh one of the things that is coming out with the technology now. Oh and finally data.

152This is a massive amounts of data. D is like way more data than we you were used to in the past. And so I already talked about the challenge of like sending all this data uh small packets or you know quickly so we can read it and analyze it. um and saving it is also a huge deal. So, uh it'll be interesting to seeing how technology grows over the next six to seven years. Uh and how we're going to be able to handle this data. There's all these giant data centers out there already for all the AI applications. And we're doing AI as well. Um and so it's like how do we you know have maintain these data centers and uh we have our data centers but it it's it's a challenge because you know

153we don't have the money that you know other I don't know Google or AWS or any of these other places has and so you know how do we maintain these this amass amounts of data and analyze it all at the same time. So there's a whole computer science aspect of the whole thing as well that we're working with as well. I mean I think Alan already covered it all. So uh but yes like yeah the improvement really over the next years we we already know some improvements we'd like to make to the earthquake early warning algorithm aquafare monitoring Alan mentioned that D especially for offshore uh location we really believe in that and then as I said my shake I mean we really want I mean we really we have this earthquake early warning alerts

154now they they are accurate we really want to increase the number of end users we want more automative actions because it's good we produce this alert but they need to be used. So I think what I would really like to see over the next 10 years is this all to be much more used uh by by the public but also by by the organizations and maybe one point slightly on the side I'd like to mention is that as Alen mentioned we have all these great data now we can do a lot of things in addition to earthquake early warning but for earthquake early warning we'll need to in average I think so we have about 1,100 stations in California and we will need to to basically upgrade this equipment about every 10 years. So I

155think a big challenge is going to be to make sure that this network is maintained over time and that we are ready for the big ones because if we let it deteriorate then the data would be the big one. Then our network will not perform as good as it performs right now because we have a brand new network. It's performing extremely well but we need to make sure that we can maintain that over time. So again we are ready for for the big one whether it happens in Southern California or in Northern California. Well, adding to what Julian mentioned, uh we have 1150 stations contributing to early warning now, but still we we have cases that there would be uh false alarm or there would be some uh earthquake uh with uncertain location or size.

156So I think maybe this is one item for the CISn team to get together and see what solution we have. Of course that's is one of the solutions for the areas that we can use that. But what else we can do to make sure that we have the coverage that we need for the early warning notifications. That's one thing with all the information that we get from early warning. I see a big potential to provide service for emergency responders. And on the top of all Jalo, yes, I think there is a big potential for improving what we started and add to that and provide uh tools for emergency responders and also there are very critical structures in California. The early warning uh records and information can be used for uh providing very quick information to

157the stakeholders to collaborators to agencies in California that they need to get the information right away after earthquake. We have many uh uh very important toll bridges in California that we need to cover. uh we have dams, tunnels and etc. that the information from early warning also hospitals that information from early warning can be uh processed and provided very quickly within seconds to to everybody for responding to our scripts. >> I thank the three of you for that. I think that's great. We have some amazing conversations so far on this panel. So again, thank you for taking the time to be with us. I want to open up to our board members to seek any questions, comments about what we've talked about in the panel. I just want to say uh it's impressive where where

158we came from and where we are now and I'm really looking forward to seeing the future. Um, just going back to the reporting that was done at the beginning, that earthquake near Santa Cruz, 91% of the people knew that earthquake was going to happen before the swave hit. That's huge. I if you think about it, not what, a decade ago, no one would have known. It just would have happened. So the progress we're making is is incredible and I look forward to seeing these ideas being put in place and more progress being made. So thanks. >> Uh just overall if you had some thoughts about the accuracy or false positives moving forward. I mean I know it's a whole series of tech you know the physical device that senses the ground motion and then a

159network and then software and then another broadcast then an enduser device and so it's a bunch of things working in serial but just overall I mean do you see you know two years five years 10 years is there some sort of quantum improvement in accuracy you see does that make sense >> yes totally but but already I would like to say that since 2019 actually we had only one really true false alert out of um what's the I think the right number right is 186 alerts that we have issued for the entire west coast of the US and most of them being in California so I think the system is really already extremely reliable but what happens sometime is that as we explained in the case of offshore events we're going to slightly overestimate the

160magnitude so we're going to slightly over alert So sometime we're going to end alert. So we are more into the fine tuning in the system. But already I think I'd like to insist on the fact and it's it's quite impressive actually that yeah we delivered 186 alerts and only had one one main false alert since 2019 and uh and so I think the system is already at a very high level of performance. >> Yeah. And I was just going to add we talk about offshore Nevada is another place where there's just a sparse network. Um, and so we get data from Nevada, but if there's uh just like one station that's uh off, then it can make a false alert um because of uh or at least or take a real earthquake and turn it

161into something, you know, much bigger magnitude than what it actually is. And so uh the these spar the spark networks is kind of what we need to cover. So in that regard, uh people are working in Nevada very hard to try to bring them into shake alert uh officially and if the state it joins officially then they'll get money for uh sensors. Uh so they'll fill in the holes there and so that would the two these are the areas we're really really working on is the offshore Nevada and actually I'm trying to work with our partners in Mexico quite a bit too uh to densify there because that's another source of where we get errors. So, >> okay. Any additional questions from the board? Uh, checking public. No public comments. Uh, thank you Brandon. Thank

162you to the panelists. Uh, quick question and check everyone's temperature. We have a fivem minute break that we can take now. Or do you all want to power through? Keep it moving. All right. So, uh, with that, to continue our EEW Advisory Board meeting, we'll have our California Council on Science and Technology fellow Cara He provide a system operations update. Thanks again to the panel. Thank you so much for the introduction, Derek. Good afternoon, everyone. My name is Cara. Uh, I'm the CCST fellow um supporting earthquake early warning um for until October. Um, and today I'll be sharing system operations updates. Okay. So, Calloas Earthquake Early Warning Program continues to partner with the California Integrated Seismic Network, CISN, to reach our goal of 1,115 seismic stations as required by California Government Code 8587.11. CISn is

163responsible for generating EEW alerts and managing system operations which include the ongoing maintenance and performance of the California earthquake early warning system Q's powered by Shake Alert. We are currently in the final stages of the network buildout with over 96% complete and only 50 stations remaining. The increased station density is crucial for reducing alert latency and ensuring comprehensive statewide coverage. The number of stations has increased to 1,65, which reflects an increase of 19 stations that have come online and are contributing to earthquake early warning since the board last met in June 2025. Out of the 1,115 stations, 702 is the number of Q's funded/planned stations. Callowas and our partners have completed 700 out of the 702 planned Q's funded EEW stations with the final two stations currently in progress with the USGS and the Berkeley

164Seismological Laboratory. Callowas public safety communications continues to work to connect EW stations into the state microwave network and secure tower/volt leases. There are 173 out of 317 EEW stations online and connected to the state microwave system with 144 remaining. And that is that is the system operations updates. >> Thank you, Cara. Uh chief deputy director, any questions or comments? >> Thank you, Cara. No comment. >> And I'll turn to the board to see if there are any questions. and online. All right, thank you, Cara. Uh, we will now have Julie Leo, our emergency services coordinator supporting uh, education outreach and research and development provide an update on the financial overview of the EEW program. >> Thank you, Derek. Good afternoon, board members and guests at Callowas. Before we discuss the 2025 2026 spending plan and

165some of our projects, I will discuss the 2025 and the 2026 business plans. The 2025 business plan was recently approved by the governor's office and is now visible to the public through our website. The 2026 business plan is currently going through the executive review process. The earthquake early warnings ongoing funding of 17.1 million from the general fund is approved. We continue to prioritize funding for system operations and the development of the California earthquake early warning system which proven to be a vital safety tool for the state. We have allocated dedicated funds to ensure the optimal system performance and to deliver essential EEW and earthquake preparedness messaging to the public including hardto-reach and underserved communities. These efforts are supported by ongoing rapid response and our outreach letos California grants. Through our research and development, we continue

166to support the integration of EEW into other sectors by advancing projects such as expanding my shape capabilities, the airport implementation grant, and future projects. Thank you. >> Thank you very much, Julie. Uh, chief deputy director, any comments? >> Thank you, Julie. No comments for sure >> and for the board and none online. Okay. As we transition to closing remarks, um I'd like to take a moment to acknowledge and thank our board members for your continued support, whether it's supporting the MyShake extension roll out support with our projects or paving the way for seismic station locations is truly appreciated. Um, and additionally, it's a bittersweet farewell to our system operations manager, Philip J. Lobra, as this will be his last EEW meeting as a member of the EEW team due to his recent acceptance of the

167program manager 2 role as my counterpart over the Calloway earthquake tsunami volcano program within the seismic hazards branch. Phil, thank you for your contributions to this program over the past few years and we look forward to collaborating with you on further endeavors within our branch. And with that, uh, board members, do you have any final questions or comments, I'll turn to Chief Deputy Director Bastic. >> All right. I just want to say thank you to our panelists today for joining us and sharing with us your insights, your enthusiasm and your collaboration on EEW. Appreciate that. Appreciate our uh advisory board members for coming out and uh thank you for your continued engagement, for your assistance in uh achieving our many successes in EW. Uh we hope you all learned something today. I know I did.

168Um, it's been a pleasure to be involved with the advisory board today and I look forward to future dialogue. Thank you. >> Thank you. And checking to see if we have any comments. Uh, deputy director and jury any closing comments. All right. Uh, with that we can entertain a motion to adjurnn. Would anyone like to motion? And a second. All right. All those in favor say I. All right. The eyes have it and we are adjourned. Thank you.
