>> 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 haddes. >> it's not going anywhere. we 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 easier.

>> do you know know your greg giving hurts from your wifi you may think that computers are kufz but when you know what you need it gets easier. a computer is made up of many different parts and each part as a specific job the k public works u is the brains of the compute. it's where all the work is done. current computers have multiple coarse it means it has multiple k public works ushthss working together as one. it hold all the information in the ram or hard or hard drive.
