>> hi. i am cory with san francisco and we're doing stay safe and we're going to talk about what shelter in place or safe enough to stay in your home means. we're here at the urban center on mission street in san francisco and joined by carla,

the deputy director of spur and one of the persons who pushed this shelter in place and safe enough to stay concept and we want to talk about what it means and why it's important to san francisco. >> as you know the bay area as 63% chance of having a major earthquake and it's serious and going to impact a lot of people and particularly people in san francisco because we live on a major fault so what does this mean for us? part of what it means is that potentially 25% of san francisco's building stock will be uninhibit tabl and people can't stay in their homes after an earthquake. they may have to go to shelters or leave entirely and we don't want that to happen.

>> we want a building stock to encourage them to stay in the homes and encourage them to stay and not relocate to other locations and shelters. >> that's right so that means the housing needs to be safe enough to stay and we have been focused in trying to define what that means and you as a former building official knows better than anybody the code says if an earthquake happens it won't kill you but doesn't necessarily say that can you stay in your home and we set out to define what that might mean and you know because you built this house we're in now and this shows what it's like to be in a place safe enough to stay. it's not going to be perfect. there maybe cracks in the walls and not have gas or electricity within a while but can you essentially camp out within your unit.

what's it going to take to get the housing stock up to this standard? we spent time talking about this and one of the building types we talk about was soft story buildings and the ground floor is vulnerable because there are openings for garages or windows and during the earthquake we saw in the marina they went right over and those are -- >> very vulnerable buildings. >> very and there are a lot of apartment buildings in san that that are like that. >> and time to. >> >> retrofit the buildings so people can stay in them after the earthquake. >> what do they need? do they need information? do they need

incentives? mandates? >> that's a good question. i think it starts with information. people think that new buildings are earthquake proof and don't understand the performance the building will have so we want a transparent of letting people know is my building going to be safe in it after an earthquake? is my building so dangers i should be afraid of being injured? so developing a ranking system for buildings would be very important and i think for some of the larger apartment buildings that are soft story we need a mandatory program to fix the buildings, not over night and not without financial help or incentive, but a phased program over time that is reasonable so we can fix those buildings, and for the smaller soft story buildings and especially in san francisco and the houses over garages we need

information and incentives and coaxing the people along and each of the owners want their house to be safe enough. >> we want the system and not just mandate everybody. >> that's right. >> i hear about people talking about this concept of resiliency. as you're fixing your knowledge you're adding to the city wide resiliency. >> >> what does that mean? >> that's a great question. what spur has done is look at that in terms of recovery and in new orleans with katrina and lost many of the people, hasn't recovered the building stock. it's not a good situation. i think we can agree and in san we want to rebuild well and quickly after a major disaster so we have defined what that means for our life lines. how do we need

the gasolines to perform and water perform after an earthquake and the building stock as well, so we have the goal of 95% of our homes to be ready for shelter in place after a major earthquake, and that way people can stay within the city. we don't lose our work force. we don't lose the people that make san francisco so special. we keep everybody here and that allow us to recover our economy, and everything because it's so interdependent. >> so that is a difficult goal but i think we can achieve it over the long time so thank you very much for hosting us and hosting this great exhibit, and hank you very much for joining >> hi. welcome to san francisco. stay safe and

exploring how you can stay in your home safely after an earthquake. let's look at common earthquake myths. >> we are here at the urban center on mission street in san francisco. we have 3 guest today. we have david constructional engineer and bill harvey. i want to talk about urban myths. what do you think about earthquakes, can you tell if they are coming in advance? >> he's sleeping during those earthquakes? >> have you noticed him take any special? >> no. he sleeps right through them. there is no truth that i'm aware of with harvey that dogs are aware of an impending earthquake. >> you hear the myth all the

time. suppose the dog helps you get up, is it going to help you do something >> i hear they are aware of small vibrations. but yes, i read extensively that dogs cannot realize earthquakes. >> today is a spectacular day in san francisco and sometimes people would say this is earthquake weather. is this earthquake weather? >> no. not that i have heard of. no such thing. >> there is no such thing. >> we are talking about the weather in a daily or weekly cycle. there is no relationship. i have heard it's hot or cold weather or rain. i'm not sure which is the myth. >> how about time of day?

>> yes. it happens when it's least convenient. when it happens people say we were lucky and when they don't. it's terrible timing. it's never a good time for an earthquake. >> but we are going to have one. >> how about the ground swallowing people into the ground? >> like the earth that collapsed? it's not like the tv shows. >> the earth does move and it bumps up and you get a ground fracture but it's not something that opens up and sucks you up into ha. it not going anywhere.

are going to have a lot of damage, but this myth that california is going to the ocean is not real. >> southern california is moving north. it's coming up from the south to the north. >> you would have to invest the million year cycle, not weeks or years. maybe millions of years from now, part of los angeles will be in the bay area. >> for better or worse. >> yes. >> this is a tough question. >> those other ones weren't tough. >> this is a really easy challenge. are the smaller ones less stress? >> yes. the amount released in small earthquakes is that they are so small in you need many of those.

>> i think would you probably have to have maybe hundreds of magnitude earthquakes of 4.7. >> so small earthquakes are not making our lives better in the future? >> not anyway that you can count on. >> i have heard that buildings in san francisco are on rollers and isolated? >> it's not true. it's a conventional foundation like almost all the circumstances buildings in san francisco. >> the trans-america was built way before. it's a pretty conventional foundation design. >> i have heard about this thing called the triangle of life and up you are supposed to go to the edge of your bed to

save yourself. is there anything of value to that ? >> yes, if you are in your room. you should drop, cover and hold onto something. if you are in school, same thing, kitchen same thing. if you happen to be in your bed, and you rollover your bed, it's not a bad place to be. >> the reality is when we have a major earthquake the ground shaking so pronounced that you are not going to be able to get up and go anywhere. you are pretty much staying where you are when that earthquake hits. you are not going to be able to stand up and run with gravity. >> you want to get under the door frame but you are not moving to great distances. >> where can i buy a richter scale? >> mr. richter is selling it. we are going to put a plug in

for cold hardware. they are not available. it's a rather complex. >> in fact we don't even use the richter scale anymore. we use a moment magnitude. the richter scale was early technology. >> probably a myth that i hear most often is my building is just fine in the loma prieta earthquake so everything is fine. is that true ? >> loma prieta was different. the ground acceleration here was quite moderate and the duration was moderate. so anyone that believes they survived a big earthquake and their building has been tested is sadly mistaken. >> we are planning for the bigger earthquake closer to san

francisco and a fault totally independent. >> much stronger than the loma prieta earthquake. >> so people who were here in '89 they should say 3 times as strong and twice as long and that will give them more of an occasion of the earthquake we would have. 10 percent isn't really the threshold of damage. when you triple it you cross that line. it's much more damage in earthquake. >> i want to thank you, harvey, thanks pat for >> hi today we have a special edition of building san francisco, stay safe, what we are going to be talking about

san francisco's earth quakes, what you can do before an earthquake in your home, to be ready and after an earthquake to make sure that you are comfortable staying at home, while the city recovers. ♪ >> the next episode of stay safe, we have alicia johnson from san francisco's department of emergency management. hi, alicia thanks to coming >> it is a pleasure to be here with you. >> i wonder if you could tell us what you think people can do to get ready for what we know is a coming earthquake in san francisco. >> well, one of the most things that people can do is to make sure that you have a plan to communicate with people who live both in and out of state. having an out of state contact, to call, text or post on your social network is really important and being able to know how you are going to communicate with your friends,

and family who live near you, where you might meet them if your home is uninhab hitable. >> how long do you think that it will be before things are restored to normal in san francisco. >> it depends on the severity of the earthquake, we say to provide for 72 hours tha, is three days, and it helps to know that you might be without services for up to a week or more, depending on how heavy the shaking is and how many after shocks we have. >> what kind of neighborhood and community involvement might you want to have before an earthquake to make sure that you are going to able to have the support that you need. >> it is important to have a good relationship with your neighbors and your community. go to those community events, shop at local businesses, have a reciprocal relationship with them so that you know how to take care of yourself and who you can rely on and who can take care of you. it is important to have a battery-operated radio in your home so that you can keep track

of what is happening in the community around and how you can communicate with other people. >> one of the things that seems important is to have access to your important documents. >> yes, it is important to have copies of those and also stored them remotely. so a title to a home, a passport, a driver's license, any type of medical records that you need need, back those up or put them on a remote drive or store them on the cloud, the same is true with any vital information on your computer. back that up and have that on a cloud in case your hard drive does not work any more. >> in your home you should be prepared as well. >> absolutely. >> let's take a look at the kinds of things that you might want to have in your home. >> we have no water, what are we going to do about water? >> it is important for have extra water in your house, you want to have bottled water or a five gallon container of water able to use on a regular basis,

both for bathing and cooking as well as for drinking. >> we have this big container and also in people's homes they have a hot water heater. >> absolutely, if you clean your hot water heater out regularly you can use that for showering, drinking and bathing as well >> what other things do people need to have aren't their home. >> it is important to have extra every day items buy a couple extra cans of can food that you can eat without any preparation. >> here is a giant can of green giant canned corn. and this, a manual can opener, your electric can opener will not be working not only to have one but to know where to find it in your kitchen. >> yes. >> so in addition to canned goods, we are going to have fresh food and you have to preserve that and i know that we have an ice chest. >> having an ice chest on hand is really important because your refrigerator will not be working right away. it is important to have somebody else that can store

cold foods so something that you might be able to take with you if you have to leave your home. >> and here, this is my very own personal emergency supply box for my house. >> i hope that you have an alternative one at home. >> oh, i forgot. >> and in this is really important, you should have flashlights that have batteries, fresh batteries or hand crank flashlight. >> i have them right here. >> good. excellent. that is great. additionally, you are going to want to have candles a whistle, possibly a compass as well. markers if you want to label things if you need to, to people that you are safe in your home or that you have left your home. >> i am okay and i will meet you at... >> exactly. exactly. water proof matches are a great thing to have as well. >> we have matches here. and my spare glasses. >> and your spare glasses. >> if you have medication, you

should keep it with you or have access to it. if it needs to be refrigerated make sure that it is in your ice box. >> inside, just to point out for you, we have spare batteries. >> very important. >> we have a little first aid kit. >> and lots of different kinds of batteries. and another spare flashlight. >> so, alicia what else can we do to prepare our homes for an earthquake so we don't have damage? >> one of the most important things that you can do is to secure your valuable and breakable items. make sure that your tv is strapped down to your entertainment cabinet or wall so it does not move. also important is to make sure that your book case is secure to the wall so that it does not fall over and your valuable and breakables do not break on the ground. becoming prepared is not that difficult. taking care of your home, making sure that you have a few extra every-day items on hand helps to make the difference. >> that contributes dramatically to the way that the city as a whole can recover.

>> absolutely. >> if you are able to control your own environment and house and recovery and your neighbors are doing the same the city as a whole will be a more resilient city. >> we are all proud of living in san francisco and being prepared helps us stay here. >> so, thank you so much for joining us today, alicia, i appreciate it. >> absolutely, it is my pleasure. >> and thank you for joining us on another edition of building
