>> 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 >> hello.

welcome to "culturewire." we are here today with bay area artist jody chanel, and we are here to see the plaza where your piece has just been installed. >> i have been doing large-scale paintings in the galleries and museums, and the idea that in the future, i could do something that would hang out a little bit longer than the duration of the installation the kind of appeal to me. i quickly found out about the san francisco arts commission school and realized there was a pre-qualified school you had to apply to, so i applied to the. >> how long did it take you to develop this work for the plaza? >> this was a fast track projects. design development was about a month.

>> let's look at the beautiful mural. i have never seen a mural created on asphalt. >> the heat of the asphalt, a new layer of asphalt. then, these wire rope templates that were fabricated for the line work get laid down and literally stamped into the asphalt and then everything was hand-painted. >> maybe you could talk about some of the symbolism, maybe starting in the middle and working out. >> [inaudible] the flower of industry. >> it is like a compass. there's an arrow pointing north. >> within the great bear consolation, there are two pointed stars here. they typically lead one to the northstar, otherwise known as polaris.

so i thought it has a layer of theme. >> let's talk about some of the other elements in the peace. we are walking along, and there is a weather vane. there's a sweet little bird hanging on the side. what kind of bird is that? >> [inaudible] the smallest of the gulf species, and it lives around the bay area. >> you want to talk about the types of flour patterns that you send? >> [inaudible] around 1926 or so by the dahlia society. >> what is this bird here? >> that is the california quail. >> coming up here, we had a little blustery theme. what is this area here? >> this is supposed to be the

side view, the expense of the golden gate bridge. >> there it is. >> there are really beautiful elements of architecture still around i would say that it gives that feeling over to the work. >> what are your hopes for it? >> that in a way it just becomes part of the area. i think it is starting to have that feeling. people utilize it. they sit and, and have their lunch and play on -- they sit and, and have their lunch and play on that -- they sit and come and have their lunch and play on it. just for it to be part of the neighborhood. that is my hope. >> is such a beautiful addition to our public art in san francisco. thank you for joining us. it was nice to meet you. and thank you for telling us about your beautiful mural.

thanks for watching "culturewire." >> i love teaching. it is such an exhilarating experience when people began to feel their own creativity. >> this really is a place where all people can come and take a class and fill part of the community. this is very enriching as an artist. a lot of folks take these classes and take their digital imagery and turn it into negatives. >> there are not many black and white darkrooms available anymore. that is a really big draw. >> this is a signature piece.

this is the bill largest darkroom in the u.s.. >> there are a lot of people that want to get into that dark room. >> i think it is the heart of this place. you feel it when you come in. >> the people who just started taking pictures so this is really an intersection for many generations of photographers and this is a great place to learn because if you need people from different areas and also everyone who works here is working in photography.

>> we get to build the community here. this is different. first of all, this is a great location. it is in a less-populated area. >> of lot of people come here just so that they can participate in this program. it is a great opportunity for people who have a little bit of photographic experience. the people have a lot, they can really come together and share a love and a passion. >> we offer everything from traditional black and white darkrooms to learning how to process your first roll of film.

we offer classes and workshops in digital camera, digital printing. we offer classes basically in the shooting ton the town at night, treasure island. there is a way for the programs exploring everyone who would like to spend the day on this program. >> hello, my name is jennifer. >> my name is simone. we are going on a field trip to take pictures up the hill. >> c'mon, c'mon, c'mon. >> actually, i have been here a

lot. i have never looked closely enough to see everything. now, i get to take pictures. >> we want to try to get them to be more creative with it. we let them to be free with them but at the same time, we give them a little bit of direction. >> you can focus in here. >> that was cool. >> if you see that? >> behind the city behind the houses, behind those hills. the see any more hills? >> these kids are wonderful. they get to explore, they get to see different things. >> we let them explore a little bit.

they get their best. if their parents ever ask, we can learn -- they can say that they learned about the depth of field or the rule of thirds or that the shadows can give a good contrast. some of the things they come up with are fantastic. that is what we're trying to encourage. these kids can bring up the creativity and also the love for photography. >> a lot of people come into my classes and they don't feel like they really are creative and through the process of working and showing them and giving them some tips and ideas. >> this is kind of the best kept secret. you should come on and take a class. we have orientations on most

saturdays. this is a really wonderful location and is the real jewel to the community. >> ready to develop your photography skills? the harvey milk photo center focuses on adult classes. and saturday workshops expose youth and adults to photography classes.
