i even was a little concerned about the composting requirement at first, but now i'm doing it. other folks are doing it, and it is really exciting to achieve these extraordinary goals. green collar jobs. the new economy. this is our future. this is real. it is happening now, and it could be happening everywhere else, not just in the great city and county of san francisco.

>> it is two years since we had a meeting here, almost exactly two years to the day since we had a meeting in this eeoc that was renovated and opened april 15th. you could see today, you saw the film coming in, now there's controversy about the film and when it was filmed. there seems to be some agreement that was filmed on april 14th, 1906 and today of course, this week we're looking at the 104th anniversary of the 1906 earthquake. we thought that would be an interesting film to show at the beginning. of course, that's an 0 old earthquake and we'll talk about commemoration ceremony as we move on today. i wanted to mention you also have probably noticed, there's been a lot of earthquakes around the world and i have been paying attention to that and my staff has been paying attention to that. that's what keeps us up at night. we want to do a good job for the city and county. it makes us wonder where we're

going to fall into that. we know about the predictions. today we'll talk about mapping vulnerable communities and the latest in earthquake early warning technology. as well as the new transbay term nol safety project. and in addition we're finally going to hear about golden garedian and that will take place on may 18th. the first thing i want to do. we're going to go to item 3, as you see the mayor not here, but his chief of staff is sitting in for him. item three is the executive director up date. if you look in your little brochures, you have a green piece of paper. i wanted to go over department highlights for march and april and into june. we have been participating, many departments have been participating in sunday streets. i'm not going to go over

everything but march 16 and 17 and 18 coordinated the first boot camp and our thanks to so moan departments for participating in that. human services and rec and park and the medical examiner and fire and police and sheriff's and d.p.h. and others, what we did is we -- we went to pier 48 and they provided people and staffing in order to erect the field care clinics and when he -- we had a lesson on awareness and setup of the clinics, as well as the numbering and inventory of the items that go into making up those clinics. the numbering and inventory are important in putting them back together, so when we pull them out again, we have them in the right order. that was actually a very -- big deal. and -- and just so you know, just to give you a little context in that. san francisco has six field care

clinics and 25 pod trailers. we have seven m.c.i. trailers and seven care and shelter trailers and one medical examiner trailer and a number of triage surge capacity trailers. so, we have a lot. and number of departments in the room have graciously given us room to park the trailers. so that's been another example of the city working together in logistics. we have done community meetings. the next thing i want to talk about is april 12th to 18th which is this week, is national public safety telecommunications week. we have the dispatcher of the year award and we have two dispatchers that were honored. i want to thank chief gascon who came by earlier in the week to thank the dispatchers. and his wife came by today and bringed awards to the two dispatchers of the year as well as a letter to all of the dispatchers. i want to recognize the san

francisco p.o.a. who contributed heavily and in their newspaper wrote articles about the dispatchers and the good work they're doing. as we move down the list, april 13th, i think you heard about the mayor's press conference. many of you were there. we been doing training and as we go into april 17th upcoming training exercises and events. as i said earlier, it is the 104th anniversary of the 1906 san francisco earthquake and fire. and our office has been working with a number of civic groups and the fire department and others in commemoration ceremony. you each got one of these in your brochures and on the back, you'll see the preparedness information from the department of emergency management and the department is proud to be able to work with everybody on this commemoration and be able to provide the brochure for the events. those events are open to the public and -- and can i get a show of hands on how many will you be at lotus had the at 5:00

in the morning? that's not bad. you're welcome to attend. and so as you could see, also on april 17th is the all day citywide drill at the middle school. every year they do this. this is the time to come and see how nert is doing. they have a great turnout usually. they did bringaging and a number of exercises that i think you'll find interesting if you have time to go by. then on april 17th also the san francisco fire department is doing public tours of the auxiliary water semisystem and the twin peaks reservoir. i had a chance to go on a tour last week. it was interesting and even though i didn't know -- and even though i knew a little, i found out i didn't know that much. it is interesting, the water system. and chofe, did you want to say anything on that? >> no.

then you'll seat different events surrounding the earthquake and fire are listed there again. and april 20th another preparedness outreach. you play or may not know that d.e.m. does outreach to neighborhood groups and we send out not just emergency services people but our 911 people as well to tell people about the right way to call 911, about language issues and location issues. and on april 23rd, we're going to be presents along with cal e.m.a. a senior officials training. and an emergency management communications. on april 24th treasure island, we'll keep going down. i don't want to take up too much time. on april 27th the department of public health is doing a distribution of 72 hours.org at all clinics. they come in five languages.

this is a great thing they do twice a year and they end up giving out pressures to people that come in the clippings that day. probably those are the people we really want to reach. i think this is a really good event. and then on may 18th we have the statewide golden guardian exercise and we'll talk about that later and then on june 1st, the d.e.m. is working with the -- with an e.m.s.a. working with the paramedic association and the heart association who are actually the -- the movers on this particular issue. and operation heart safe and there's going to be a press conference at city hall featuring survivors of cardiac arrest and people using defibrillators and a two-hour teaching event will follow and they're going to do that. so, ongoing projects. one thing we have been working on-ly at department of social management is media. i'm going to ask rob to fwalk this. he's the mover and driver on this. he's doing activity around the

country talking about this. >> thank you. i would say this is an example of incorporating lessons learned. if you recall back to november 2007 and our ever so popular oil spill, one of the things that -- that we recognized that we could have done better is monitoring what happened at that point on the blogs. that was before twitter was really as big as it was. i can't imagine how that has -- had been had the twitter been what it is now. one thing we took away from that the coast guard level and local level was the ability to watch what happens on the internet and to intercan't act on that and participate in that conversation and so we don't lose control of the message. that launched into basically a year of studying what is this thing called social media and how do we utilize it to our advantage and -- to reach a big portion of the population that really relies on that medium if their information. and since then we have launched a twitter stream and we have a

presence on facebook and in addition to our alert s.f. none are substitutions for our traditional methods of contacting the public or doing alert warnings like the emergency alert system or the sirens or using the media in a traditional sense. these are tings things that we added in. what has happened over the last 18 months or so, san francisco has been recognized as a leader in this area. we're ahead of the curve on cities. we're ahead of the curve more so than new york. that's is something i like to say because typically they're ahead on everything else. on this one we're way ahead and part of that is we have a administration with mayor newsom that embrace this is technology and they use it in the mayor's office as well. there's not as pump fear around it. it gives us latitude to embrace it. what happened over the past 18 machines, i get invited to share our scornses and a number of conferences around the country. and actually help to inform sort

of a national level discussion of how does it fit into emergency management and how should it be embraced even as the -- the fema and others -- like say national policy if you will but natural practice is better way to put it. thus far have been asked to come down and speak at the naval postgraduate school which is where they do the masters program. just this week, i was, monday or actually tuesday, i was in washington d.c. at the national academy of sciences where i was asked to come share this as --ee as part of the discussion around the new commercial mobile alert system which is taking the emergency alert system to cell phones. and recognizing that people don't carry a.m. radios on their belt but almost, a huge percentage of the population, some 85% of the population owns a cell phone at this point. the idea is how do we cross the technology barriers and get an alert system that would touch every device regardless of carrier. that's close to happening. sometime in the next year,

they're going to have a it finalized. they brought practitioners and academics and social scientists to have a discussion about okay, now that we have the technology side of it, what do you want to say? if you have the tool, what is the message. this meeting over the couple of days is all about, what is it good for? how do do we fit it? >> and the same thing e told them, we'll take whatever is offered. there's no one system that touches everybody, and yeel use all systems. in general we're being recognized from across the board as innovators and leaders in the use of social media and emergency management. not just for alert and warning but also for preparedness. this is a key part of a preparedness communication strategy that we put together. and last year and that is actually been recognized both in the state of california all the way up to beten house's office, but also up to -- fema and manning the preparedness assistant secretary. and so we are the -- the city is

doing really cool things that are being recognized nationally. er we're happy to do it. >> okay. thank you. >> so just one more thing. the important website at the bottom of this one is 72 hours.org, of course. the quake quiz. if you haven't seen it, take a look at it. our website where we post a number of interesting things as well as some of our plans, our after action reports and things of that nature. and then the -- the fire department nert website, we urge you to go there. the 21 remaining council meetings, just to give you a preview is friday squll 16 and friday october 15. so you could put those on your calendars. those are probably not going to change. wanted to give you a let's headsup on that. that's the end of my update. is there any discussion or questions by any members of the

council? seeing none, are there any questions or -- i'm sorry statements by members of the public? seeing none, we're going to move on. but instead of item four, i'm going to ask to go to item five for technical reasons. and so item five is a c.i.s.n. shiekh shake alert, a warning system in california. we asked richard allen from the seismological department to come. just to give us an overview. dr. allen. >> can i stand up? >> we need you talk -- >> thank you. >> thank you for the invitation to come and talk to you. develop methodologies to try to get warnings out to people before they start to kneel the

shaking in an earthquake. when i say warnings, we're talking about a few seconds tofu 10s of seconds warning. that's not a lot of time. i'm going to argue the amount of time that could put to great use and show you examples of how we can do that. my nature is rich allen. i'm a professor at berkeley and the size moll hodge cal department. i'm here with peggy hellwig who is operations manager. first of all, what is earthquake early warning? what is earthquake early warning? this is animation running in realtime. it is going to show a magnitude eight earthquake. it is the same as the 1906 earthquake that we heard about. the distances this this earthquake is starting at the top of the an san andreas fault and is going to rupture its way down to stran. that's what the gray -- this laser is much use. but this is what the brown is. this is the rupture coming down the fault to san francisco.

as it goes, it raidiates energy and p waves and the p waves are the yellow circles. it is right about now that the first wave would be arriving right where we're standing. at this point we would feel the shake but we wouldn't know if this was the beginning of a big earthquake or the main shake for a relatively small earthquake. and it is not until the s wave arrival, the red as circled started to arrive in the city that we know it is a big earthquake. it is not until the rupture itself, this brown bar as it is coming down to the south comes past san francisco that most of the daniel would be done. and you could see that is still about 30 seconds, 40 seconds from now before most of the damage would be done. and so again, it is running in realtime and this is to illustrate the point that for really big earthquakes, there's a significant amount of time between when the earthquake starts and when much of the damage is going to be done. the point of earthquake early warning is going to make use of that time.

the way we do it, we put size monitors in the region. we rapidly detect the beginning of the quake and the ground shaking likely to follow and we use that to provide warnings to people in harm's way. so what does real-time earthquake information look like today? what might it look like tomorrow? so this is what it looks like today. everybody in this room probably is familiar with shake, shake maps. this is the shake map for the alan rock earthquake. it was in 2007. it was the largest earthquake in the bay area since the 199 earthquake and these maps show the distribution of ground shabing so they show where we expect most of the damage to have been done and they're currently available in about eight to 10 minutes after an earthquake. and this is what we call an alert map. it looks just like the shape map and has the same information on

it. it shows the information as the red star and it shows the intensity of ground shaking for the -- the difference is this map is a pure prediction. and in fact the data that is this map was available before the strong shaking from this earthquake was felt here in san francisco. and i want to illustrate that in a few minutes. the idea is we could provide this kind of information seconds to 10s of seconds before the ground shaking is felt. and then people can use that to take action. and now we think of this in maps because of course we need to know what the ground shaking is everywhere. you and i as individuals. we don't care what the map looks like. all we're interested in is two numbers. what is the ground shaking going to do right where we're standing and how many seconds do we have until the shaking occurs. what we have to do is take the information and send it out to people so they know exactly what the ground shaking is going to be in their particular location. so that's one of the goals of the future. we don't have that part of the system in place just yet.

so should you believe me? can we really do this? wee had several proof of concept events. i'm going to show you the allen rock example because it is the most relevant one to this group. this is a 5.4 earthquake and 8:00 in the evening on october the 30th of 2007 and it was a good shake. you probably felt it if you were in the bay area and -- at the time. we actually got our test system up and running 20 days before this earthquake happened. so we were fortunate if the fact that we had this running at the time of this earthquake. and the first that the system knows about the -- the event, the detailed -- details are not important, but the seismic stations that are closest to the epi center first detected the earthquake and that was 19 seconds after the origin time. one second later, we have the first estimate of how big the earthquake going to be. the system is estimating the magnitude is 5.2. this was 5.4. so that is extreme my good.

we couldn't expect better. we have the prediction of what it is going to be. this is the shake map, about 10 minutes after the earthquake. this is the alert map, the prediction and this was before shaking was felt. you could see they're similar illustrating we could do this before the shaking is felt. go two seconds after that is when the data is in the system. as time progressive, we get more and mare information, we incorporate it in the system and we update the washing. -- warning. it doesn't change after the first couple of seconds, it stays stable. up in the left is actually a size gram. and this is the ground shaking for the earthquake. this is the time, and this is when the earth erupted and this is when the p wave arrived at the surface and this is the strongest ground shaking where the -- the heights of the size mo gram is greater.

and the data that is motted in the maps was available at this times relative to this graham graph. this is why we could say we had the prescription of the ground shaking before it was felt in san francisco. you could also see we're only talking about a few seconds. two, three five seconds warning. and the data at this point was available back here at five seconds. this is 15-second delay was because of how the system was running and we're in the process of reducing that down to five seconds and -- and delay. we would have more warning time in future earthquakes. and this is our first proof of concept event that demonstrated we could actually provide warnings of ground shaking before people felt it. so how much warning are we talking about for future earthquakes distributed throughout northern california? and this map shows the amount of warning time and it is basically the warning time in san francisco and it is dependent upon how far the nuke leagues of the earthquake and how far away

from from san francisco it starts. if it starts up here like the animation at the beginning, we have more than a minute's worth of warning but if it starts closer, we have less warning. >> this grayed out area, this is what we call the blind zone. this is the region if we have an earthquake and it nique lates in this region we won't get a warning. it is important to point that out. not everybody will get warnings if all earthquakes but many people will get much warning for some. >> this is the earthquake we were talking about, it is on the 10 sked contour and we would expect 10 seconds in that leeks. and this was the other earthquake and that particular earthquake we would expect on the order of 20 seconds warning. that's significant. i don't want to remind this group, most fatal talts of that occurred in san francisco in oakland, about the same distance from the event and there doob

about -- could be 20 seconds of warning in a repeat. so i want to show you examples of how early warning is being used. we have one example. we have one user group at the moment in the bay area. we're looking for more. that's part of the reason i'm here. we could go to other places around the world to look for other examples. the mosted a vnsed system is in japan. they have a topically available nationwide earthquake early warning system. i'll show you several examples from japan. mexico city has a publicly available warning system and then there are smaller systems current my in romania and also in turkey. the green lanaled here are in a development mode much as we are here in california. so, i'll take one example. and which is the largest magnitude earthquake in japan, since they turned on their warning system in october of 2007. it was a magnitude 7.2 earthquake. the japan agency that monitors

earthquakes and provide this is information issued the warning and then these are specific reports of how 24 warning -- this warning was used. and it is people in their homes and getting in safe zones and getting under tables and away from windows. people in offices same action. schools, and i'll show you in a minute. factories people moving away from hazardous environments. planes were prevented from landing and told to go around and there's somebody in a car bringing a -- the car to a stand still. and what is most important here is that there are no reports of panic. one of the issues one of the concerns we always had is that issuing a warning with a few second notice could result in people panicking and could have a greater negative impact than the earthquake itself. well we have now had several warnings issued in japan, there are no reports of panic or accidents. that doesn't seem to be a concern at least not of the same magnitude that people originally thought.

tchow they get the warning out? they use as many approaches as possible. and most tv and radio stations issue the alrts. and they have what is called the jay alert system. which is a governmental system that issues warnings. and this includes actually transmitting at 102 of them, actually announce the warnings on the public address systems in the municipalities. i mentioned that of course san francisco has such a system. and cell phones are used to get there out. to -- to people and then there's a range of dedicated devices -- this is my favorite. i look to mention this one. this is a device. it looks like the weather station you get when you go to wal-mart and you buy a weather station and it tells you whether it is sunny or going to rain. it tells you what the intensity of groun shaking is going to be. and little icons that tell you what to do and not to do. get under a table and don't run outside, things like that. a here's an example from a

school in tokyo. and they actually did a tril for us using the system while we were visiting. and so they use the system that is transmitting the warning into the school and every term, three times a year, they have a drill where they issue the warning and all of the students react as they would do during the course of the earthquake. [unintelligible] >> you could see the numbers is the same warnings and the amount of time until the shaking is felt. another example from a chip manufacture and one from industry.

and they had two moderate size earthquakes in 2003 and had $250 million of loss. they were shut down for 17 days and 13 days. they then implemented two things. they first of all implemented early warning system and built sheer walls in the basement. for the for them it the chip manufacturing requires robots to manufacture the chips. they're on an air air mattress. what they want to do is set the equipment down on the ground and that way there will be less damage if it is shaking around. when the warning is received, they set it down on the ground to reduce their exposure to earthquake damage. since implementing this they had two similar size earthquakes. it went down from 15 million to 2.5 million. and the c.e.o. came and tell us

about this. they were ecstatic about how useful the system was in their case. so finally an example here in the bay area, the gain -- the reason we're here, within reason we're here is because we are looking for groups to work with as we start to roll out this early warning system. we're currently working with one group. we're working with bart and bart is interested in receiving this information in order to automatically start to slow and stop the trains to reduce the hazard to their trains during an earthquake. and so for the -- for the shakeout, the great california shakeout last year. 10, 15 on 10, 15, 2009. we put together a prototype system, where we're streaming information into the control center at bart. they set up an application at the moment, it is a stand alone application that runs on a computer at the back of the o.c.c. and alarm goes off and they take action. this is just an animation that shows what the -- what the this

system does at the back of their operation center. it also has a very loud audible bell that goes with it. although, i don't have that part of the animation. the shakeout, when the alarm went off, this is for simulation for the low earthquake. when the alarm went off, the operator came over and issued an emergency stop to all of the drivers on the bart system. that actually took 23 seconds of course, which is eating up pretty much all of the warning time you have. they realized of course what they want to do is take this to than a automated system so in the future, once they see significant shaking like this, they will then automatically stop all of the trains. this is my last slide. this is to give you a sense of what we're doing with earthquake early warning and give you examples of how early warning is being used various places around the world. the stage we're at with our
