the granddaddy of all of these is the san andreas fault. it is the longest. it can generate the greatest hq >> it is just south of san francisco. it goes offshore down here. >> from my house to the fault is about 3 miles on average. >> the closest area in san francisco to the fault is this area here in the southwest part of the city. people said that the closer you are, there are conditions that exacerbate issues. >> the fault's effect on development depends on the fault type and soil component. the san andreas is the main fault. there is the hayward fault. the difference between the two is that the san andreas is predominantly offshore. the hayward fault actually crosses beneath populated areas and poses a larger threat. as we speak, there is a 67% probability of a major earthquake on one of these faults in the next 30 years. it is of major -- high probability. it is a magnitude 6.5. the 1906 was 7.9. the 1957 earthquake was 5.7 on the san andreas. the loma prieta was 7.1. it was so far with it we got a little effects of it. that is the overview of the geolog

the san andreas, which is off shore of san francisco, and is about how far off shore? maybe a mile. so it's very, very close to the city and runs up to marin, >> a million years of earthquake movement created. that used to be in southern california. it's an active fault and the other is the hay ward fault. geology and other people say this is a fault that is more likely to have slippage. and the hay ward fault runs through the university of california >> right through memorial stadium, i understand. >> it's one site moving relative to the other >> and downtown san francisco, the heart of san francisco, this is basically almost exactly between the hay ward faults and san andreas. >> although if you live in the richmond district and the hay ward fault goes off, you won't feel the earthquake. you won't be able to stand. >> so what you're saying is the closer you are. >> that's why it's good to be in the middle. if you are on one extreme and the fault goes off, the shaking will be pronounced >> how many people were in san francisco in 89? anyone in the marina in 89? >> if you were in th

this is closest to the san andreas fault. many people believe that the closer you are to default, the greater the ground motion might be. that is a portion that is a south westerly portion of san francisco that has some special earthquake hazards. we are here to talk about the geology of this area. why don't you tell us about what is going on? >> there is a giant step here at the edge of the escarpment, the edge of the landslide. all the land to the west of us is part of a landslide that is upwards of 200 feet deep. it goes underneath the ocean. it causes damage and it was mapped by the earliest geologists'. there are many kinds of rocks here. there is a big sequence of merced formation. this is a base in deposit that was formed by the interaction at the end of the continental margin. >> this is just on top. this is the same material that we were looking at at the last site. you can see it is on our way to the last side. it is deposited here by wind. it is 40-50 feet thick. this acts as a big sponge. the water flows through a

we probably won't get that on the haward fault, but on the san andreas fault. they will have very pronounced shaking. we will also have more interaction because of poor soils that interact with earthquake waves. you can have a moderately distant waves and it will be higher in the bay area and people don't realize how much of the city has been filled. there's a tremendous amount filled in and in those areas, the ground will shake dramatically harder. there's a lot of interaction that plays into the interaction of the intensity. >> this map was adopted by the state of california after its study of the areas that are potentially liquifiable. they are wet areas or fill areas that amplify the earthquake forces >> you can actually have the ground turn to liquid like quick sand. >> if you look at the map, there are green areas and blue areas, just so you can understand, the blue areas are potential landslide areas. that's a different issue. but we do have potential landslide areas. all the green areas are potentially liquifiable. if pat says, you are going to have.9 g

hayward fault is so overdue probably a 30 or 40 percent chance in the next few years whereas the san andreasthe grounds shaking that came out of the report was around 50 to 60 percent of gravity. to give people an idea, '89, most of san francisco was 9. so to think that your house would shake five times harder is kind of the concept that it's hard to grasp that level of shaking. >> so i guess getting back to the issue what the public believes, public believes that their houses are safe enough or they would not be allowed to be in them in some cases, many cases. if i talk to my neighbors, that's what they say. it's been here we've gone through the other earthquake. are the public exceptions reasonable -- expectations reasonable and if not whose job is it to help them expectations of who to help them form risks, graib umbrella? >> i'll jump in. san francisco is a crazy place to put a city if you were going to be planning one, and that's okay. we -- we know what we should be doing to make it as safe as reasonably possible. i think the lessons of katrina are making a lot of us realize that that'

i'm standing pretty much directly on the san andreas fault and this is really important for southerna. what's odd here is this fault has right-lateral movement to it, and so what we're looking at here is the continental landmass of north america coming into contact with a different plate. this land over here has moved over 400 hundred miles in the last 20+ million years from where it used to be attached to mexico to where it is today, and that, that's one of the engines of biodiversity here in this part of california. >>♪music. >>those winter rains bring late winter and spring flowers to the desert too. the desert comes alive with flowers! every shrub - the encelia, the burrobush, the creosote bush, and then herbs everywhere. we have fagonia in full-flower out here, and lots phacelias, scorpionweeds, it's just incredible the amount of variation we find in the desert and this one, one i haven't seen before but we all know it, tobacco. did you know that tobacco is an american plant and the native americans used it and they used this one. imagine - our tobacco came from a desert heritag

now he's going to blame the san andreas fault and the oklahoma dust bowl and depression on who else butty dig meg ph e megaphone. >> just in case some of your friends or neighbors, uncle jim's a little stubborn, been watching fox news, but you don't have the to take my word for it. if you talked to somebody saying i was watching fox news and they said it's horrible. >> fox has been critical of the president. >> sure, on the prn side. on the news side, you know, straight up fair and balanced, and the problem is, this is the old scapegoat of politics for centuries. if not the millennium. you blame someone else for your own problems. and so mind you, there's a leadership gap in this country. whatever happens, we've got extremists on the left and a very big part of extremists on the right as well. it's the president who's supposed to bring leadership to this country and avoid a government shutdown. avoid a default. if we get into a position where he would rather blame fox news or rich americans, that's wrong. and i think it's not good for the future of our country. >> and furthermore, the p

andrea roane. >> enjoy another day in san diego because we're having it today. >> we're in southern california. >ng the coronado but we have stuff they don't have. >> including their weather. >>xactly. it's beautiful out there. a little chilly. temps down in the 30s in a few spots. there was some frost near win winchester and cross junction. frost advisories well west of us toward garrett county. today we're going to warm up slowly. 53 by 8:00 but by lunch time midz 60s. going to feel pretty good out there during the middle of the day and the winds a lot less than yesterday. only about 5, 8 miles an hour. 73 at 4:00. we're going to poke to 74, 75 for a high. very, very comfortable. clear skies overhead. we do have some cloudiness southwestern virginia with some fog as well in the mountains and temperatures, look at this, now down to 39 in winchester. 37 in frederick. manassas dipping to 39 where fog is forming and fredricksburg, andrews and gaithersburg all in the mid- 40s. as far as the fog, it's spread sparse but where it is in frederick, three-quarters, it was a mile in manassas so that's an i

san francisco. i also want to recognize some of our legislative staff members that have spent quite a bit of time on this. amy chan, andrea [speaker not understood], ivy lee in particular in my office is a former attorney at api legal outreach and asian caucus and community for civil rights. they did a lot of work to being as creative as possible in terms of narrowing the carve out. so, we are specifically addressing as much as possible the specific concerns of our public safety officials while passing the strongest possible due process ordinance that will be in effect in this city. so, unfortunately we do not have the languages today. they will be ready for our board meeting next week. so,ly will be making a motion to continue, but i did want the public to know exactly what the amendments are that we are introducing today. >> thank you, supervisor kim. supervisor kim has made a motion it continue. is there a second to that motion? seconded by supervisor cohen. supervisor wiener. >> thank you, mr. president. and i, whatever folks' differing views of aspects of the legislation, i want to thank everyone who has worked on ge

andrea roane. >> glad you're with us. a little chilly this morning. good morning, monika. >> i put a swelter on. >> the -- sweater on. >> the afternoon a different story. >> another beautiful day. take that, san diego. we've got your number, at least for another week and things will change around here by later sunday into monday. today as mike and monika said, a little chilly start. we have 40s out there with high clouds giving us mostly cloudy skies now but it's going to be a beautiful day. lunch time 72 and sunshine and light winds. if you're not outside for lunch today, you're missing a great opportunity. we'll see a high of 77 degrees. back down to 70 by 8:00. so another nice evening to get outside, take a walk with the hubby or the wife and just enjoy. look at this. we've got some high clouds coming in here. a few sprinkles out in the ohio valley ahead of a cold front which just doesn't have enough moisture to work with. fog has been a problem in the mountains. not too bad but a bit around warrenton. culpeper victs have improved -- visibles have improved. this is the chill we're talking about with 45 in winchester. 46 manassas. it's 50 in fredricksburg and pax river naval air station. ev
