fire. what we're seeing now, neighbors told me it started with a small fire and suddenly erupted. neighbor rs saying it was a terrifying morning around here. >> i woke up and went back to sleep. everything in the house was all over the place.

dressers, tv, all went down. >> how long did it take for the fire? >> well, the house, immediately we could see there was a fire from the gas or something. it started burning. it took about 10 or 15 minutes for the fire trucks to get out here and it went down quickly. >> my whole bed shook. i heard a really loud noise. my mirror fell. i ran to see if my mom was okay. . >> was she okay? >> yeah. she was okay. >> woke up on the floor. i was wondering what was happening. i tried to figure out what was going on. i had never been in an earthquake before. >> nap pa county tells me four

homes burnt down. you can see the melted siding and fence there. this home also has structural issues. if you can see there, it has a lean to it. it came off the foundation. not as bad as other homes. this is the mobile home park where we saw a few injuries where people went to their door tos find out that the stairs had separated from their house and they fell down. i talked with a veteran while the earthquake was happening. he said they were watching tv and the entertainment center was on its side. he wasn't moving very well and said it was the most terrifying moment of his life. he had to get the entertainment center off of his wife so she wasn't crushed.

people very scared and shaken up. i have seen people literally shaking on the street. their homes are gone. some of them are just going to have to rebuild. that's what we're going to have to deal with out here at the nap pa valley mobile home park. >> we want to remind you there are two evacuation centers. one at nap pa high school and one at grace church. for those just joining us, we want to recap. the earthquake has now been reupgraded to a 6.1. >> u.s.gs will assess their information a lot over the next couple of days and they will increase or decrease and keep the magnitudes. it was a 6.1 originally then downgraded to a 6.0. the damage is the damage. that's not going to change.

it's right around the city of nap pa. not too far from fairfield. it hit at 3:20 this morning along the west nap pa fall -- fault. back in january we had a 5.2. . >> that is a fault you don't think about too often. you think about many others. we did speak earlier with someone from the usgs to see what effect it could have on the larnler faults. this is something they will be analyzing over the next 24 hours. it could have indeed released the pressure on the other faults. >> it's a double edge sword. it release the pressure in some

spots, but it could also inprees the risk of in another spot. the big circle is the eventual strong quake. all those tinier circles are all the after shocks we've had over just the five hours. we're now up to 18 after shocks of magnitude 2.5 or larger, six of which occurred within the past hour. >> the largest after shock we're aware of was a 3.6 that happened a couple of hours ago. there is still a 50 pblth chance --% chance of an earthquake. chance -- this could have been a foer shock to a larger quake that could hit within the next week.

>> these are the numbers we're working with now. we just had a strong earthquake. magnitude 6.1. could it be a foer shock? yes, small chance, but it's not 0. now, we're getting some pretty interesting video coming in. now, the people are waking up and are able to send us video. >> we have some surveillance video from the moment the earthquake hit. >> it's about to hit. you can see everything shaking there. a couple of things falling off the walls and we'll see the people waking up. >> i'll put it out there, my house shook more than this. >> everybody had a story to tell. we've got so many calls here in the kpi news room. people that were jolted and

woken up at 3:20 a.m. >> i fell asleep on the couch and all of the sudden i woke up and there's this loud rumbling. i thought it was a thunderstorm. we have a chandelier in the do i think room. everything was falling and i heard something break. i ran upstairs to regroup with the family and made sure everything was okay. >> she was able to laugh right now, but 87 people have been treated at a hospital in napa. three of those people in critical condition. from what we understand injured from things falling on them in their home. >> this is the strongest one in 25 years. you may think a six is a tiny bit bigger than a five, but we're talking about a big difference than anything we've had throughout the past century. >> up to two feet per second

in terms of how fast the ground moved. that is significant shaking that can cause damage to structures. 40% g's. so it was 40% of gravity. gravity would be what we feel in terms of what's keeping us on the earth and it was 40% oaf that in a lateral direction. that would cause destruction in modern structures. they generally designed to we hold shaking about that. but how fast that shaking occurred is fast enough to deform the ground. that's why we're seeing a lot of broken pipes and so forth. it causes enough strain in the ground, it just can't accommodate that motion. this was a strike slip. so lateral motion, and there are

multiple faults in that area. it was close to the west nap pa fault. this is east of the hay ward falls. you have lateral motion. so that means there was no strong vertical uplift. the earthquake in japan that caused the tsunami, this retires this type of motion. in california, particularly in the bay area, you tend to have a strike foot fault. so our plate bount ri is deforming in a lateral direction where one plait is sliding past each other rather than one dooifg underneath another. >> that was brad with the ufgf. >> just think about two plates. these were two huge earth

plates. they're locked. stuck. it's building up energy. that energy is built up and eventually it snaps. most of the time, they're snaps you don't feel. every once in a while, the pressure gets built up so much it sends out energy in all directions. real interesting. you said it's 40% g. here's my smart phone. this is the force of gavty. that force, is gravity. think of that force now going sideways. that's what you felt this morning in your house. that's why it felt like you had your sea legs. 40% of the force, pulling down, that's how much energy was going back and forth. >> that's why we felt it for

-- such a wide ire ya. >> the whole building was swag back and forth. people reported feeling it in is a lean in a. as far east as carson city ne vad da. --nevada. >> we want to review the damage we're getting in. the injuries, 87 patients being treated at a hospital in napa. several gas line breaks they're dealing with now. some of the breaks with contributing to a couple of fires burning in the area. 30 walter mains have broken. we have a lot of people without water now. a lot of people, tens of thousands of people without electricity. one at grace church in nap pa is set up for people.

>> it seems to be centered in the old buildings in nap pa. it is still significant damage in neighborhoods, too. >> let's check in with joe. he's been checking out some of that damage. >> we're in nap pa, southwest nap pa. this is pretty dramatic. this is the kind of scene we're seeing around here. this is glen's drive way. it's raised almost a foot up where it should be. there is substantial cracks in the drive way and right over there, you can see cracking there. it's significantly off the foundation right now. this is the sort of scene we're seeing here. i want to walk you over to the corner here. there is a water main break k. maybe the water department was able to shut it off or maybe it ran its course.

here on the corner, neighbors said they were fixing this curb, but clearly it snapped off. look at this. right here, this part was attach today that and afached right there a -- attached right there. it just snapped. when you talk about an earthquake, those are the scenes embedded into our heads. this is the kind of situation we're seeing throughout this neighborhood. seen some xhim anies fallen down in the street as well -- some chimneys fallen down in the street, too. person after person told us about stuff falling from inside their homes, crashing down on top of room after room. sir, let me ask you, you were telling me you had damage inside your home? >> everything. almost everything fell off the shelves.

>> what did you feel when the earthquake hit? >> scared. our tv came down. everything fell. . >> your neighbor here, mr. hubbard, i saw his drive way. what do you think about that when you see this in your neighborhood? >> it's scary. i've never experienced anything like this. >> well, we want to let you know this came in. cal train is not running which will be a serious problem. you have a 49er's game this afternoon. so no train service. bart however, is running. it won't be helpful if you're trying to get to that stadium. >> even though it was 50 or 60

miles away, they're saying inspections, that's the smart thing to do. you want to make sure the tracks are safe. inspections are likely to cause delays all morning long. a lot of folks who wrp taking the cal train down, you will likely be delayed this morning. you may have to consider paying $40 for parking on the peninsula. >> that game is on on the race way for this afternoon. speaking of transportation, let's go to the highway patrol. daniel, i was amazed to hear that known of the bridges were affected by this. all the highways are open? >> that is correct. up in nap pa valley we have two roads damaged.

along 121 over on state rout 29 and a little on state rout 12. aside from that, our highway system is doing pretty well considering. >> tell me about the process. it was at 3:20 in the morning. what happened? how do you hit the road trying to fig year out where there may or may not be damage after something like this? >> most people know we provide there the bay area up to 12 different regions. every area office divides their region. the officers are assigned to them. they're out on routine patrol in any case. they just go about their day looking for damage to the road way or over head passes, whatever there maybe as part of the their routine patrol visually looking for any damage they can find.

obviously, that's easier in the areas that are free way, but the ones out in the highway, there's more road way to track down. but they hit the major road areas and we depend on the citizens to help us find anything we didn't detect. >> daniel, a lot of those roads are elevated. aside from a visual inspection, what else will happen over the next hours and days to make sure the structures are safe? >> the officers will continue to inspect them when they drive over. of usually -- obviously, it will be easier now that it is light out. they will dispatch engineers out to the major road ways to make sure they are all in good condition. that will take sometime. oftentimes the road ways will

be fine even just with a visual inspection. what we see out there determines whether or not they're safe to drive on. then cal trance can make sure they are safe for the ongoing future. as you know, they've spent a significant amount of time retrofitting all the structures in the bay ooir ya for est quakes. in fact, the upcoming closure of 280 is just another one of those efforts to really earthquake proof or earthquake resistant all of our structures. >> i just want to take a moment to be thankful that this happened at 3:20 in the morning. what would have been different from your perspective had this happened during say a rush hour, when you had a lot of people out on the road way? >> we could have seen many, many more collisions than we saw this time around. you're right.

the time of day did help mitigate that factor. we had only a couple of property closures as a result of the earthquake. it was mostly because of the road way changing shape in a couple lo kaikss. with earthquakes, it is unpredictable. you can't predict it when you're driving. if you are in a condition where there is more traffic on the road, you may have seen more collisions and injuries. luckily, there were no injuries on the road ways. most damage or injuries were caused from inside the homes. >> thanks for joining us live on the phone this morning. >> we'll continue to get in more video from different parts of the pay area. it seems to be centered around nap pa. let me show you a video of a

postoffice in downtown valejeo. >> a lot of storm fronts dleeng up thorn -- they're cleaning up this morning. a lot of businesses will have their phones ringing off the hook. >> we have video. a store self is no match for a magnitude of this earthquake. you'll see all the major stores having a tremendous amount of damage as whatever was on the self is now on the ground. >> yeah, we had a video from a safe way. the employees were running out into the parking lot and coming back into the store to see a real mess. new video from vele ijo. that

is probably happening all around nap pa. the question is this just cosmetic damage or is the structure of the building damaged, a too? ? >> looks like we have a nice new bump on highway 12. >> yeah, live from chopper five. we've seen a lot of that on road ways. it hadn't really impeded traffic, but some of these up to 1 to 2 feet. cal trans making quick work. >> how about that, highway 12, earthquake happened on saund morning 20 minutes after three 3 andthe road will be repaired by 9 9 o'clock. good job cal tran. >> they have a lot of work to do.

there are roads buckling all over that area. a lot of that damage yet to be discovered. another concern of course, is the piping underneath the gas lines and water mains which may have been compromised. i think at lost count we had 30 main breaks around the area. a lot of people are without water this morning. latest check, there were 30,000 people without power. they are going to have, it will be a huge job to try and restore power to people. 30,000 without u poer thorn -- power this morning. >> we're looking at all the earthquake roerpts. -- reports. >> they rely on getting accounts throughout the bay area. how strong was it where you lived? they received reports pretty far north and south.

they felt it in fresno andn evada and all of our local cities. . >> look at that buckle in the road, this is what it looked like about an hour and a half ago. you can see several layers of road way there. buckled, coming up, but not enough to stop traffic. they still let people go through that area. i do have to stay, they have kept the bay area moving. let' remind you again about the public transportation. cal trans not running. they're checking the tracks now. >> barts from the ace train coming from the delta. could be folks from sacramento coming down for the game.

there could be issues getting to the a's game or the 49er's game. >> the producer just told me that they are running special service to the 49er's game. that just relieved a lot of traffic problems we could have had been the next several hours. cal train is rung special service -- running special service to that game. they will likely be up to normal service once they can check the potential damage to the track. of kous, it runs significantly south of the canyon. it's unlikely that there was damage to those tracks, but better safe than sorry when you're talking about train derailment. >> obsoletely.

-- absolutely. >> that's not small damage. that's highway 12, and it buckle ld and lost t. ground won. the highway lost. . >> but again, they are going on with the se gnome ma race way shafter known. there was a lot of damage around that area. the sh. >> they gave us probabilities because nobody knows exactly what's going to happen. there was a 54% chance that we will see an after shock five magnitude or stronger. we had this morning a six. a five is nowhere near strong as a six. six.

>> those could stumble in something as strong as a five. i think the most eerie statistic is this light chance that this earthquake could have been a fore shock to a larger quake. that is a possibility we have to be aware of over the next couple days. >> it's something to keep an eye on. it's a lot higher than it was before 3:20 this morning. let's go to julia. julia downtown. there's a big tile of bricks behind you. . >> anne, this is really the center hub of downtown nap pa. we're giving you a different look now of another street corner. this is pretty typical of what we're seeing. look how it's completely shattered the windows and the bricks. it's almost as if it's tilted

by 30 degrees or so. if you look down you can see the bricks on the sidewalk here. that's just one general area of yourselfly blocked off to the public. as we give you more of a sliz usual -- visual walking tore, you can see what the magnitude of this earthquake did to the hi toric build -- historic buildings down here. if we pan around, my photographer can show you, this is the courthouse. the superior courthouse. obviously, that now, is not going to be in service for quite sometime. you can see if damage that was done to the exterior of the courthouse. we don't know really what it looks like inside because there is that concern that if there are after shocks or just any concern that this building may go at any time if there is an after shock or if it's not safe now.

so we're taking you akrogsz the street to another building. this is a law office and a bail bonds office. you can see the top of that brick building also. . the windows as well, shattered. alex, we'll go the other way and show you across the street and see people lined up. obviously, people getting a first look and first light of what's happening. you can see huge rocks in the middle of the street. i'm told across the street is the county administrative office. that building is no longer in use now because it has water damage. they had to move to another part of town. beyond that building, happens to be the jailhouse. i'm told, rest assured, that

building's fine. . as far as the central area here, there's a lot of damage done. the main chern is keeping people away. law enforcement gave us access to show you pictures. when we're done with this, we move out of the area as well. i would imagine they will noouf barricades farther out. because in no time this building could collapse in either direction. keep in mind paul and anne, when we got here, 4:30 in the morning people were out here with their flashlights trying to see what the damage was. then at first light we got the first look at the serious

structural damage at the heart of nap pa. >> a lot of people were woken up by this earthquake. we want to run down some of the facts this morning with you. it was a 6.1 earthquake that hit. the epicenter was near the american canyon that is in nap pa county and close to the nap pa airport. >> yeah, the arment is -- aurpt is south -- airport is south of downtown. rather a shallow quake. so more of the enjerry was near the surface. >> we have julia live for us in downtown nap pa. thank you for that report. we have people surveying the damage to homes, to road ways. then injurz.

we have to remind you there were 87 people treated so far at hoopt in nap pa. three people in critical condition. they were injured by things falling in their homes. one of the three people is a kield air lifted to another hospital this morning. >> folks maybe wondering, map -- nap pa? it does have a history of creating earthquakes. this one stronger today, a 6.1. as we've already seen, 18 after shocks stronger than magnitude 2.5. they say there is a 54% chance

of a magnitude shock. >> this earthquake hit at 3:20 a.m. a lot of people have been up since then. let's recap for you one more time, the detail ofs what we're dealing with this morning. because these picture rs still coming in. the magnitude has changed several times. >> it went down and up. it's the same earthquake even if that number changes a little. currently it's sitting at a 6.1 with most damage occurring in and around the nap pa area. a area. 89 people have been treated at the valley of the queens

hospital in napa. three people in critical condition include ago child. several homes have been damaged. four mobile homes we saw burning earlier. we have a reporter live on scene at that mobile park. evacuation centers set up now at the high school and grace church. a lot of people will be wondering today, especially around this canyon area, is my home safe? my first thought, person to person, if you have any doubts, go to one of our evacuation sites. . >> we did speak with an an engineer this morning who told us with what to look for. the foundation of your home, the water heater and also, the fireplace. if you notice a door maybe not opening or more difficult to open, that is a sign of serious

structural damage. >> we've seen pictures on facebook in cracks in the wall as far away as oakland. we will have hundreds of reports of this minor damage in people's hoiss. -- houses. just because you have a crack in the wall doesn't mean there is a structural issue, but if you feel it is something to get checked out, certainly do. if you question your gas leaking? turn the gas off. go outside, turn that nozzle off. you do not want gas coming into the house. that's been the cause of a few of the fires. >> we did hear from two of the emergency officials. they don't want everyone shutting off their gas because then it will be difficult to turn it on and it could take days to get it back up and

running. i think that is something to keep in perspective. these are the things people will be dealing with ef over the next several hours. a lot of the clean up will be done on the store fronts. items just littered with debris broken bottles. the clean up will be significant. let's talk about the transportation significant because we actually lucked out. known of our highways are closed and known of our bridges are closed. so if you're getting around by car, you'll be okay. bart is running. they may also have their other service up and running once they check the tracks. >> i think we have a press

conference in napa now. >> we have some information we'd like the pass along regarding the current operations. first of all, i'd like to turn it over to mike. . >> that's randolph. i'm city manager. i just wanted to announce that in response to the emergency that occurred early this morning, we have activated our emergency operation center and effective at seven: 59 we declared an emergency. we have brought in all available forces in the work force to come in to assess damage, provide services.

work is under way. we're busy now surveying all of the various complaints we've received and establishing priorities. we brought a number of resources in this morning to talk to you. why don't i introduce john who's with the fire department who's handling the operations this morning. he can explain what we're doing in terms of responses and we have some of the other technical support. . the deck will ration states of emergency means we have exhausted our local resources. we need more help from the outside. we're asking the governor. both the county and city are asking the governor so we can access resources through the

state office of emergency services and perhaps beyond. so it's sympathically a deck loo ration to determine -- declaration to determine we need help and is serious. we will have an itemized list of what we need within the next couple of hours. we have not had communication. we just made the declaration about an hour ago. we will expect that to occur in the future. john? good morning, obviously, as the fire chief poirnted out -- pointed out, we've had about a tote of six fires. one of them involved six mobile home tos together. all four of the six are completely damaged. the other two suffered major damage. additionally, we're still in the faze evaluating the

buildings out there to know exactly what we have and where we need to place our priority resources. we have strike team that are in here helping us out as was mentioned by the city manager. our resources are exhausted in terms of on duty personnel. in these situations that happen state and nationally, we call outside resources for help. we have about 100 plus gas leaks. medical calls in the neighborhood of about 80 plus. the queen of the valley hospital has been filled with patients all related to the trauma incidents after the earthquake. one major incident of a fireplace falling on a young person is in critical condition

and has been flown out to a neuro center. our crews are trying to catch p -- up with the calls. rescue crews are in rout here, plus some that are in town now. that's about all i have. the public works director will talk about the infrastructurish use and go from there. . i'm the operations chief from the fire department. there were two criticals that i'm aware over. i don't know the exact nature of them.

i'm going to assume this is all trauma related injuries from falling debris et cetera. we have no reports of anybody missing at this time. . >> can you identify all those? >> can you repeat that. >> have you identified all the gas leak ins the area? >> no. we are still getting calls of that nature. we are working hard to identify any leeks. additionally, we haven't seen any after shocks with such significants. i understand two of them in the 2.something range. they're anticipating the range of five plus for after shocks. i haven't felt them yet. >> chief, a lot of people out

there looking at the buildings where there's rubble. any word about the danger of getting through? >> please, stay away. we've done our best and are still working on isolating those areas. we've tried to close down downtown. these buildings that are obviously damaged, stay away. they're going to go out and evaluate those items. it's the common sense side. please, stay away from the buildings that look like they're leaning. >> any recommendations where people can go? >> there's a few in -- if you don't smell gas, you're probably safe. .

>> do you have an idea of how many over all structures? >> yes, again, we're in the mid ol' of an assessment. i'm let someone else speak on that. . >> separate mobile home park -- with that i'll let jack come up and answer them further. . >> jack larochelle, public works director. first up, the reports on the gas leeks that -- leaks that we've gotten, we're chasing them down. we don't know the eventual

number. we have crews working on that. the big thing we're working on is the water main system. our whole water system. there's been reported of about 30 water main leeks or breaks. a lot of them in the bounce area which is west of town. that's to be expected. that's a geological area and is more sus spebtable to damage. what we're trying to do is isolate those leaks. shut off the water to those areas as quickly as possible. now to provide water throe and volume, we've opened up our other water plant in hen si. we have two feeds. one from the south and one from the north. our water plants were fine. they were not damaged. that's the upside.

we are feeding water. the tank levelling did start going downright after the earthquake. those have been stabilized and are starting to come back up. when we were able to get the other plant in operation. . the first issue is getting the water back on as quickly as possible. the water is safe to drink. i'd say that. and what we're doing afterwards, then we have to set out assessment team to assess the damage. my understanding so far, is there is some road buckling issues, but nothing as far as any catastrophic failure of any bridges which is good news at least in the napa area.

from a structure standpoint, we have a team of folks who are inspectors and we'll get some experts to go through and assess properties. we don't know how many there are and what the extent of the damage is. but when we find something that is problematic, we'll red tag it and tell folks not to be around the building for safety purposes. then we'll go from there. we just don't know yet. as soon as we get that information and it's confirmed we'll make that available. >> it seems more likely you'll have 100 or 200 structures damaged than dozens. . >> i can't confirm that now. that's speculation. i have no idea. you can see some of the damage downtown to the older buildings, certainly.

we just don't know yet. . >> [inaudible] i know it's lerlly, but anything along those lines. >> rick is one of our, in charge of planning. >> , the o oker. jack is right. don't have numbers to tell you at this point in time as far as the number we've red tagged. we're trying to make sure we have people on the street identifying these buildings as quickly as we can. with regard tos the reinenforcement, our urm, most of our buildings in the downtown area have been reinforced.

we have just a handful that have not. whether or not those are the ones that are connected to work that has been don or not -- done or not, we're not able to collect that information at this time rather than make assumptions. . >> representative, please. . >> [inaudible]. >> they vard. of the ordnance we've had, there have been improvements made over time. some have been as recan he notally as the -- recently as the last eight months and others were several years ago. it varies. >> is it a retirement? >> it is.

the deadline has come and gone. as a result, there are very few that have not completed the reinenforcement. we've been pursuing that, but i don't want to draw a conclusion tony structures that are out there now. we just don't have enough data to tell you that. . >> who are you? >> i'm the community development director. >> steve potter. i'm the operations captain there, i would like to say our 911 system and all law enforcement public safety systems are operating as normal and enhanced. i think we have relative calm in the community because i think a lot of it had to do with the overwhelming response

of firefighters in town who came in without being called in. with that being said, we are working on secure any the downtown area. we will have for several days a high police presence. that's to provide asisz tans to the citizens of towns. right now, we have jefferson street and third street, a lot of that has broken glass downtown. the potential for further damage to take place. the napa sheriff's department is taking care of security at the courthouses and department of corrections. with are -- we are very tharngful for the communities. we've already received a lot of donations as far as lumber to board up windows.

we've been spoending to -- responding to a lot of calls. it makes us that much easier for us and helps us provide other services to the community. . the system was maxed out for a short time, which is till -- typical. several years ago we had another earthquake and we went through that. >> what was the chief emergency? >> they roepted -- reported a gas leak issues, fires, a whole host of things people were calling about that were brought on by this natural disaster. >> what about downtown, the windows and doors falling off in concern of people going in and steeling things? >> we've had relative calm for this magnitude of an an earthquake.

those donations were made and we're trying to board up the windows. we're trying to secure them as quickly as possible. we have not had reports of luting or anything like that. >> come on up and have a good time. i would check on your reservations at any restaurants or wineries. but up valley and downtown, a lot will remain business as normal. that's not to take anything away from the residents and businesses that have suffered, but a lot will be business as normal. we just ask they stay out of the dangerous areas where there's glass or might get hurt. no other questions,ly turn it over to city manager mike. >> just for clarification before we close, when we say

there have been 100 gas leaks, those are calls we've received from people worried about gas. that doesn't mean we've confirm confirmed hype line -- pipeline has has vard -- hazard. we will do these briefings on a regular bases. about every three hours until things slow down. we'll have more information and give you more detail in terms of numbers on what's happening out there. in the meantime, for people to receive more information, anybody can take a look at our web page at city of napa.org. they have the whole front page

dedicated today ta and details -- dead at a timed to details and data. bury martin can be contacted at extension 7817. that's 258-7804 and extension 18 sh what did i say? 7804. someone's writing this in -- 7817. 2587517. bury martin. . >> just to clarify, there were 506 gas leeks. people said within 100 power lines down and gas leeks?

>> those are the calls we've received related to power and gas. we're in the power of determining what that means. the numbers are changing all of the time. any other questions? ? >> [inaudible]. >> it's my understanding, the serious injuries were due to falling debris. i don't believe they were related to the fire in anyway. >> that is correct. thank you. . >> we have been watching live the press conference from the city of napa. we heard from all the city emergency departments. they said we need help. they've declared a city of emergency.

that means local resources are exhausted. they're hoping state resources will start pouring in. it went from a 6.1 to a 6.0. we had the strongest earthquake in the bay area since 1989. it happened on the west napa fault. it is being called the south napa earthquake. it runs up and through south or east of clear lake. this fault has a history of earthquakes. back in september of 2000, today, one of our lesser known faults is now very well known because of an earthquake that happened this morning. it was felt from top to bottom in the bay area. sas far south as the sierra as

far east of fresno. >> you're looking at pictures on highway 12. cal trans did quick work. all bay area bridges are open this morning. six homes destroyed in this earthquake mainly by fire. there were six separate fires burning in napa and one fire destroyed six homes because they were very close together in a mobile home park and about eight other homes are unlivable now. some of them knocked off of their foundation. we just heard from that press conference, more than 100 gas leeks have been reported. . >> our reporter who was on the

scene told us all of them had gas lines coming into the house. the list of damage is pretty significant. all along first street, all the beautiful brick buildings, most of them if not all of them are damaged. the good man library, the courthouse, just to name a few. store selves any where around the napa area, stuff has been knocked down. there's a lot of damage now in this vicinity. . >> we heard the water is safe to drink. an evacuation is set up at napa high school. can he not? ? >> good morning. we're live here at the survey. we're speaking with a physicist.

he had interesting numbers talking about how fast some of the waves moved. . >> up to 40% g. that is significant shaking that can cause damage to structures. 40% g. so it's a lateral excel ration in terms of gravity. gravity is what keeps us on the earth. that's enough to cause damage particularly in the unreinforced mason their structures. modern structures are designed to with stand shaking about that. but how fast that shaking occurred is enough to deform the ground and that's why we're seeing a lot of broken pipes and so forth because of how fast ground moved. but if it causes enough strain

in the ground, the pipes just can't acome mo date that motion. this was a strike slip. so lateral motion and there are multiple map faults in that area. it was close to the west napa fault. this is east of the hay ward rogered creek system. the horizontal direction you have lateral motion and so that means there was no strong vertical uplift. . the earthquake in japan that caused the tsunami, that retires this type of motion. in the bay area we tend to have strike slip fault. the hay ward creek system is too. our plate boundary is one plate sliding past each other.
