san andreas fault is about 800 miles long. take a look a little closer.the napa valley very fertile soil. these are sediments this is the luvial soil which means it's lose and things tend to really shake. you do get and we're seeing that a lot of damage in the napa area. because the soils. what you're living on has a lot to do with how things go where you live. the epicenter was about 4 feet. this is about average for this fault. the depth about 6 miles and as you know the closer to the surface the epicenter is the more strongly felt the earthquake is felt. and speaking of being felt. this is the shake map. this is one of the most telling tools we have when an earthquake first happens. people call in and report what they actually felt. you can see over here in the yellow right strong. look where it is. very isolated. but here's the thing to note. lake tahoe all the way over to point arena. south to monterey. look at the coverage of people who felt this. as far south as mammoth lakes and the big suhr area. take a look at where all the action was. right the

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

obviously hearing about the san andreas. now we know about it. it is active and there are hundreds of these small faults throughout the bay area. >> they have a team of geologist and his scientists going up there now. seven. they are going to mount that exactly. that is part of their work continuing through the day and week as people all take on their own portion of t business owners will be cleaning up all day. doctors and nurses still treating people in the hospital. 120 people went in. most are now released, buzz we know that several of them were -- because we know that several of them were, woke up, got out of their bed, stepped on glass, things like that. we have six critical injuries. one child that was hit by a falling chimney. those are being treated, we are hearing a lot of that is broken bones and compound fractures and things like that. >> very impressed. not to give too much of a personal opinion with the reaction from first responders. from what we heard live on air from those at the hospital, from the firefighters, from the help of

fault, which is the one that typically gets the most press, the san andreas fault runs to the south and west of where this quake was centered, so this quake was on an entirely different fault line or at least it would appear so, but you know, it was, it's sort of an omnipresent danger out here. we live with the fear of earthquakes all the time. we've been way overdue for a long time. our neighbors to the south in southern california have had a much more, a lot more quakes in the last 6 to 12 months, though januarylogical a smaller. we haven't had any significant quakes in northern california for some time, so we're all very aware that we've been overdue for some time. >> well, we're so glad that you're okay, too, augie, and emily as well, who we spoke with. emily is in napa. if you're just joining us, this is a 6.1 magnitude quake that has rocked california this morning. it's only 5:10 in the morning out there, but it seems an awful lot of people are wake, some of them on twitter say they're praysing or aftershocks, there's significant damage as you can see from the pictures, these

our problem is not simply an extension of san andreas fault, need more dedicated study in the region. reauthorization of nehrp to characterize poorly understood risks. our cities in america have not been testified since relatively mild earthquake that hit suburbs. funding level should be high to accommodate new developments such as earthquake early warning and cflar monitoring. the pacific northwest, to prepare we should build earthquake early warning system, monitoring, vigorous science and engineering effort and all this requires a reauthorized nehrp program. thank you for the opportunity to speak. >> thank you. dr. desroches. >> thank you. 50 years following issen an unprecedented period how to build to minimize impact of earthquakes. as a result we are much more prepared, much safer and much more resilient. however, much more can and should be done to protect our infrastructure. let me highlight a few areas where we've made significant progress. building codes will woefully inadequate at the time of the 1964 alaska earthquake. buildings that were designed and built 50 years ago wo

it did take place in napa on a fault that was not the san andreas fault which is the one that typically gets the publicity, but in famed wine country. >> we are playing live pictures from the quake area today. we are seeing a house on fire there. this is a great concern for firefighters because of gas leaks, et cetera. for viewers who haven't felt an earthquake before can you describe how it felt when you went through this a short time ago? >> there are two types of earthquakes. there is one that gives off a sharp jarring jolt and then other ones are almost wave like that are softer and have a rolling feeling to them. some of it will depend upon what type of earth surface you are on whether you are on sand or bed rock. in napa a lot of the ground is sandy based that used to be part of san francisco bay many millions of years ago. in san francisco where a lot of us are on bedrock this was a very rolling, if it is possible to call it a gentle earthquake in some regards, a strong but gentle earthquake. at least where i was it wasn't a superjarring jolt. it is very startling especially when

and everyone knows the san andreas fault. we also have the hayward fault and the calaveras fault. the earthquake actually occurred on the west napa fault which is thought to be an extension of the calaveras fault this is a strike slip fault. this is this is a side to side fault you can see of this fence on one side of the fault line displaced a couple of seats. this is the movement we saw. what we've been seeing above the earth as well is pretty disconcerting. we have historical buildings with the roof just falling in. let's go back down to the newsroom with more pictures. >> justine waldman let's get right to it a. these are the best pictures we have seen today. this is an entertainment center that toppled right over. the house did not lose power but underneath you see broken glass all over the entertainment center. parts of stereo equipment on the ground. these are pictures sent to us by steve who is 20 years old. he was badly injured because he had a fish tank above his and that broke in fell on top of him in the middle of the night. he went to the hospital and he has stitches

but the san andreas fault runs off shore here. this is a different fault. it is part of the same system. this north american fault, this plate is here, this plate is moving to the north. i get all of that. but this i don't believe gets to the point where we say it is a precursor to the big one, i don't think so. napa seeing a good shake. 17,000 people saw significant shaking. down here, where there's no dots there are very few people. this couldn't have happened in a better spot, other than napa, in other words in the san francisco bay area a. all day we have been talking about how the bay area got hit. the bay area felt something. if you think of oakland, san francisco, east bay, a shake, a jolt but not the devastation we see in napa. think of the same jolt in downtown san francisco or oakland or anywhere along the east bay. that's the story today. i know this number has been changing and it is getting on people's nerves the 6.0, 6.1. my producers hate. this earlier today the usgs tweeted out and said it is 6.05. we don't know whether to round it up or dow

it took place along a little-known fault line, not the san andreas fault. why is that so significant? >> most people are used to the steady drumbeat message that we give the public to be prepared for earthquakes. we talk about the fault that most people are familiar with, the san andreas, calaveras, hayward. these faults are capable of magnitude seven, sometimes magnitude eight earthquakes. the magnitude scale is a -- an algorithmic scale. you have 100 magnitude sixes for tha that. yesterday we had a magnitude six. they're more frequent and are going to be occurring on little-known faults because they're trying to take up the stress related to the motion of the pacific and north american plates. >> we always hear about the big one coming. could this quake because of where it occurred trigger a larger quake, a bicker quake, a stronger -- bigger quake, a stronger quake? >> it's always possible this is a fore shock. main shocks are preceded by fore shock. as time progresses, the likelihood goes down. immediately after the earthquake, there was a 54% probabilit

the san andreas and the hayward faults. and the worst-case scenario happened october 17th, 1989.ou may remember this scene from the loma prieta quake. a 220 ton section of the old bridge collapsed. traffic came to a halt for over a month. how big of a danger zone is this? >> it's a major one. >> how close are we to one of these faults right now? >> we are very close. the hayward fault runs right along the hills. >> the bay bridge is a stunning engineering feat for another reason, something that's not visible at first glance. crumble zone technology. until now, crumple zones have been used by cars. they control deformations. the old bridge won't collapse even in a powerful quake, engineers say. marwan was a engineer during the last quake. being. >> if you want to be if a big quake hits? >> the safest place will be on the top of this bridge. it would be one heck of a joy ride but it would be a safe one. >> this is how nadir are describes this, the engineering community considers this be game changers. the first one is the sheer link beams, inside the 525 foot tower. >> the sheer li

the san andreas fault is beneath us. it's a fact? when you go to school growing up in san francisco you do the earthquake drills. like in other parts of the country they do lockdowns for all kinds of -- in san francisco they still have the earthquake drill where they teach you to get under your desk and put your arms over your head and hide or stand in the doorway. so we were trained. this was the kind of training you got. you're always waiting for it. ironically it comes at 3:00 in the morning when you don't know where your shoes are. that's why there's so many people going to the hospital with cuts an their feet because no one was prepared for it to hit at 3:00 in the morning. it is one of those things you are always wondering when the big one is going to hit. if it happened during the day you would have seen a lot more casualties. i guarantee it. >> how dare you talk faster than me. thank you alexander pelosi. >> i remember the nuns getting us under the desk and saying drilling for nuclear war with stallen back then. they'd say yo

this really wasn't even on the san andreas fault, a different fault, still part of the same system, the plates are still shifting from california, the north american plate, pacific plate. put it into perspective where we are today at a 6en 0 or 6.1, usgs keeps flipping back and forth, i don't understand that, that doesn't matter. compared to where we were 25 years ago, this was nine times less powerful than 1989, loma prieta. you go here the 8, 19.08 there, 180 times, somewhere in there less powerful than back out here. the strength of the 1906 right here, about 80 to 90 times more powerful than what we had right now, what we had today. so, there was an awful lot of shakinging you have to remember in 1906, there wasn't much there there, we have a 6.1, right around there, 130 of these earthquakes happen every year on the globe. so one of these earthquakes every three days. but not like where people live, not where we saw that type of damage that we saw today. here's what happened. let's tend that these are two blights. i know they are two blocks of wood. you get the idea. one the pacific

the san andreas is 800 miles long. when that 800-mile long fault hits, it gives you a bigger jolt.'s a shorter fault as faults go. >> a lot of people felt it. >>> thank you for joining us tonight. unfortunately this is a story we're just beginning to report. i speak for all of us when i say our thoughts are with all of you who have been affected by this. because a lot of people have been affected. you can find continuous coverage on ktvu.com. the morning news will start at 4:30 in the morning. >> they will be following all breaking news and road closures that could impact the morning commute. our thoughts are with anyone who may have suffered injury or damage in this quake. good night. it makes me happy to go on the computer. i like feeling smart. internet essentials from comcast has brought low-cost internet access to over 1.4 million low-income people at home. internet essentials helped me progress in my schoolwork. it helped my grades move higher. today it's the largest broadband adoption program in america. it helped me a lot. comcast. helping to bridge the digital divide. >> f

the most famous the san andreas . this earthquake happened at least near the west napa fault. we haven't determined exactly. nonetheless, that is where all the activity is coming now. you can see the last 24 hours we have had numerous earthquakes of magnitude 1 or greater. sop of these up to 3.6. it looks like the possibility of some more. in fact, really about a 5 to 10% chance of a magnitude 6 plus within the next six days. it's 36% chance of a magnitude 5 plus in the next six days. so we're not done just yet. of course, all those damaged buildings could easily come down if we see another quake of that strength. all right. around the bay area right now low clouds and fog just beginning to break up outside. the temperatures in the 60s. and also the 70s. as we head around the bay today we will note those clouds peeling back towards the coastline. returning to low clouds and fog overnight tonight. then mostly sunny and some warmer weather on the way. high pressure going to be building in as that ridge builds in. we are going to get more sunshine. getting hot in the valleys. 94

very little effect on the san ann degree i san andreas fault. so that is a fault that will be watching closely and so far we have not detected any earthquake activity on that fault since the earthquake this morning. that's the good news. >> brad aagard joining us from the usgs this morning. we know you have a lot of information to piece together this morning. let's check in right now with andrea. she is in napa where we have seen four homes burn this morning. tell us what you're seeing right now. >> take a look behind me. you can see the smoke has severely dispated at this point. napa county fire have just told me they, with the exception of a little bit of water are seeing put on this fire right now are going to let this burn out. that is because of a water main break at the entrance to this napa valley mobile home complex. so far, four of these mobile homes have burned to the ground. neighbors tell me the fire started nearly immediately after the earthquake. they say it took firefighters 5 to 10 minutes to get here. by that time, they were ver

usually we're dealing with san andreas or the -- it's a fault line we're not as familiar with as the major ones. the west napa fault lines. when we talk about fault lines, we've learned this for so many years, it's always the soil and what it's like and why it's -- there's so much movement. rob, one of our meteorologists is with us. when we talk about the soil, but in wine country, a lot like the marina in san francisco, what we had in 1989, but in wine country it's that soil which is that softer soil and more unstable. is that correct, rob? >> you're absolutely correct, raj. when you do compare loma prieta, you will the major damage we saw around san francisco, it's due to the soft mud and the sedentary type soil that you're referring to. it has a way of amplifying and increasing the amount of shaking motion, and specifically downtown there right along the edge of the river, you're absolutely right. it's another location similar to where the epicenter was where you have the softer bay mud, d sedentary mud in downtown napa. in those locations even potentially even locations further a

>> this is withstanding the work with the san andreas fault. we have across the hayward faument. fault. the bay and the second tunnel gives us much more resiliency and the pipelines that we built out of division five. we built retrofitted pump station and across transmission lines across the city. we are praepg for that event to occur sometime in the future. will it is survive, that's the question but we are better prepared than 1989. >> i'm talking about the actual pipe? >> the actual pipes in the ground, we are using the material that is flexible. that's what we used in our water distribution system here in the system. and that has some give to it more than the older iron pipes or steel pipes. >>president vince courtney: thank you. are there any public comments on the general manager's report? yes, please. >> thank you, i think that's a great request that you asked whether or not it could withstand in an quake. i didn't hear a yes or no but i'm assuming it's no. we

it's not the san andreas fought or hayward fault line. we are now on the map as american canyon earthquake. so i'm going to look into that. >> reporter: sherry thanks her lucky stars her home's quake damage wasn't worse but her neighbor not so fortunate. many people shied away from quake coverage due to the high price and high deductible. it cost a little over $1,100 a year for a house worth three-quarters of $1 million. that's on top of your standard home insurance. the deductible is around 10%. the california earthquake authority has a premium calculator on their website so you can find out what your yearly cost would be. some homeowners use the money they would have spent on insurance and put it into the cost of retrofitting their house for 5-$5,000 for a 5,000 square foot home. their cars were damaged in the earthquake, most auto policies will cover it. >> residents ofano ferrell street building in san francisco cleaning up this morning following a two-alarm fire. the blaze broke out 11:00 on saturday morning. one elderly woman was ta

the san andreas is a system of faults. they are taking up movement all the time.ut the speed the fingernails are growing. moves against north american plate. since we are talking about rocks even though plates may be moving slowly the rocks themselves get jammed up. pressure builds up and they fail. there is a whole sequence of faults in the bay area that have the potential for building up strength and have the potential for a major damaging earthquake. >> and there is an image that shows 63%. put on your professor hat for just a second. what is a straight slip? >> there is essentially three ways that these plates can be interacting. one is that they are pressing against one another and you get for example subduction zones around the ring of fire in the pacific. where they are diving down against the other. you can get them pulling apart or have them moving side to side. that is what happens in the case of the san andreas system. it is what we call a strike-slip fault. it moves to the right or the left. it is accommodating that kind of a movement. >> very informat

what is the potential impact of a san andreas or hayward fault earthquake on the technology industry? >> certainly in silicon valley, a major damaging earthquake that really disrupted the business, you're potentially losing your infrastructure and terms of people having to leave the area. the more we can prepare so people can remain in the area, we will not suffer from the catastrophic events we saw into trina, where people were forced to leave the area and he lost that -- into trina where people were forced to leave the area and he lost the economic the tally. >> i want to thank richard and joining us from stanford. thank you very much. hewlett packard and autonomy back in court today. could shareholders be the big losers here? at his next. ♪ >> i'm cory johnson and this is "bloomberg west." at ant's look back editorial moment for hewlett-packard, when the company decided to buy a british software rollup. it was called autonomy. it was such a disaster, the company had to write down $9 million, essentially saying the money was wasted. shareholders were kicked off and they are suing. t

always does that one decided to stay in the same spot, the north american plate, a fracture of the san andreas fault. when they slipped that rupture is what the people felt. now the reason why this was a significant shake today is because it was shallow. only about eight miles deep, maybe seven miles deep what happen really rattled the people, just rattled to the surface of the earth, not 200 miles deep so that rattling has a chance to attenuate a bit. that's what people felt today all of those big shakes during that one event today. but there have been many, many events. you talked about the aftershocksen this is what it looks like now. there's the original shake. look at other dots, 2.0, 3.oh not up to 4 yet but if you get a 7.0 quake, your aftershock could be 6. a 5.0, aftershock can be 4. talk about 6.0, you've heard it called 6.1, usgs said it's a 6.05, this doun't know if they'l rund up or down. there could 59.0 aftershock. you get a building where bricks are hanging off, that's where all of the people need to be back from the buildings. a 3.0 could knock more bricks off, zblim we'jim. >

all of this, everybody in california knows about the san andreas fault.veryone is afraid of, but this was not along that fault line. if you go to the shake map, the yellow and red area is where the impacts were felt. that star is where the epicenter of this was. the san andrea fault is right over here. in napa there are a number of other faultlines. most of them are horizontal slips. these are not like the earthquakes in the pacific basin where you have two plates coming at each other and striking. that's a different thing. you have two different plates on top of each other sliding off, but that san andreas is the big one everyone is worried about there. >> coming from the south, i'm an earthquake novice at best, so when i hear sidewalks buckling and dishes falling down, that makes sense. but the fires, are the electrical fires? >> they are gas lines getting punctured from electrical lines going down. it's a combination of all of it. >> a lot of natural gas areas out there. rick reichmuth is going to be monitoring the after-effects of this earthquake. we

the san andreas fault is closer to the coast.s is the west napa fault, only 20 only ran half of it. it could have been so much worse. the west napa fault is part of a network, they are concerned this is a precursor for aftershksup o >> thanks very much. >>> and the latest now on the american journalist free ts syria for two years by a terrorist group. this comes as officials say they are closing in on the i even s welcome. >> i'm peter, theo curtis -- off boston had not been revealed. his good fortune was he was held by al-qaeda in syria and not isis, who seems more interested in revenge than st are, in their minds, the worst people on the face of the earth. >> reporter: today this section they are going to carry out of l raise in london. because for them, the key question is not only who is he, but also where in syria is he? >> reporter: whoever he thoriti is somewhere near the syrian city of raqqah, the isis stronghold and command center, and the location of the unsuccessful u.s. raid to rescue the hostages. u.s. authorities co

we talk all the time in california about the san andreas fault line, that's the big one, right?his was an obscure fault line, 6.0, 6.1 magnitude according to some and this was a major earthquake so it gives californians one more thing to worry about that all these minor faults that crisscross the state can also be very, very dangerous. >> got that. trace gallagher, thanks so mump. >>> ten seconds before the ground rumbled in california, residents got a head's up. alert coming from the early warning system. california state senator alex padilla wants more systems line this installed and joins us now. sir, a quick technical question about the warning system. as i understand it, the system does not warn in advance of the quake. it simply warns how long it takes for the shaking to reach you after the quake occurred someplace else. it's not quite a predictor ofer quakes, is it? >> no, that's an important d distinction. it's not a predictor of earthquakes days or weeks in advance. as seismic activity begins, there's a way to get the general public, 10, 30, 60 seconds of an advanced wa

it is near the san andreas fault. the bay area needs to be ready for the big one yet to come.7 quake like the loma prieta one in 1979 would release 30 times more energy than this one did, and that's something pretty hard to fathom as folks start to pick up the pieces and try to get back to business as usual. back to you. adam: claudia, you showed incredible pictures of the wine barrels toppled over. we were speaking earlier today with a wine manufacturer out of california who said we can pump what's in the barrels out. the bigger concern is the harvest. the 2014 grape harvest is just starting. is this going to impact the earthquake going to impact the harvest, has anyone said? >> according to a trade group that represents 500 of the valleys wineries, the grape harvest will not be affected. it's all the wine prepared in the barrels, all of that that collapsed yesterday. that wine is obviously a loss. but the grape harvest itself is going to continue as usual. they just started harvesting for the white wine grapes, the chardonnays and so forth, the red wine grapes are to come, l

we all talk about the big one that might be coming, and supposed to happen on the san andreas fault.or to us that even the lesser-known faults can pack a major punch for california. greta? >> trace, what about the aftershocks? are they over? because those can be -- i mean, those are terrifying, and can cause enormous damage. >> we had one this morning. i can't tell you the magnitude of it. but it was a pretty good shaker. a little unnerving. they'll happen for at least the next week, maybe two weeks, and some seismologists said they could happen for months and months, very little ones. but when you're in this kind of a situation, that you worry that the stones teetering up top might come crashing down. that's part of the reason they have these buildings red tagged off, in case there are any more tremblers that might cause some more trouble, greta. >> trace, thank you. >>> and do you like capitalism? do you know what happens when it gets choked? gets choked? what when you run a business, you can't settle for slow. that's why i always choose the fastest intern. the fastest printer. the

so the big one in california doesn't necessarily have to be on the san andreas fault. >> could be most anywhere. trace gallagher, thanks. >>> the owner of one of the vineyards there, a family business up in napa county, says it took his family hours just to start cleaning up the mess yesterday. take a look at this picture from the store after the quake. the owner says probably somewhere around $20,000 worth of damage there, and at one point, the quake forced a wine barrel to fall and knock down an electrical box. he says he considers himself mighty lucky because the larger wineries around him suffered millions of dollars worth of damage just when harvest season is supposed to be in full swing. robert dahl is the owner and he joins us live now. man, you had a mess, didn't you? tell us about it. >> it was a little scary. woke up at 3:30 in the morning to the bed shaking, running out to see if the kids were all right. had to drive into napa, check on the winery. surprised to see obviously glass and wine broken all over. we have a small family winery in there. couple barrels had been dislo

we do know that this earthquake hit in a 44-mile wide set of major faults that are along the san andreaslt system. so we do know there are a lot of potential earthquake hot spots in this very small region. i want to send it over to chad myers in our severe weather center who has a good way to sort of understand how that earth moved. chad? >> it was a slip strike fault. and i'll get to that in a second. i can show you how the earth was moving. sliding, grinding on each other. this was not along that same fault. but there are other faults here. we think about the bay area and think of oakland and berkeley all the way down through here. we think of the marina district and san francisco here. candle stick park where the shaking happened in '89. this is north of there. this is a pretty big shake. and it's very shallow. only about 6 miles, 6 1/2 miles deep. that means if it's a 200-mile deep earthquake, you have 200 miles for that shaking to get to you. if you only have 6 miles or 7 miles deep, that shaking gets to you rather quickly and it is rather violent. it isn't padded. these are the sha

so we're used to earthquakes happening on the san andreas fault, the hayward fault. but the one that hit napa on sunday was a surprise because the west napa fault woke up. scientists trying to figure out now what else might be lingering in wine country. it's not uncommon for earthquakes to happen on faults we don't know much about or have never really been mapped but sunday's quake could end up in the discovery of a wealth of new information about seismic activity here in napa county. >> this -- this particular fault, the west napa fault, we don't have a whole lot of geological information about how often or how big past earthquakes have been prehistorically. i think this earthquake will probably trigger some more investigations and we may learn more about that. >> reporter: so the question is, on many folks's minds, still, do we have to worry about a significant aftershock from here forward? now, three days away from the event, that happened on sunday morning, the answer is yes but that risk is diminishing. we are now down to just a 12% chance of having a magnitude

we talk so much in years around here about the hayward fault, the san andreas fault.ned with the west napa fault line, a fault line we don't talk about much but that's what happened today at 3:20. this 6.0 quake. napa's airport remains open. the damage from the quake has closed the air control tower so this shot here from the nbc chopper really shows you the damage, those windows there, shattered. there's a lot to clean up. the faa we've been in touch with says it could take weeks to have new windows manufactured and then installed but other than the windows there is no structural damage so that's the good news. structural damage to the tower, it's just the windows. the airport is working to set up a temporary tower until the repairs are made. in the meantime, this napa airport north of downtown will be open with the tower unmanned like it usually operates during nighttime. >> nighttime it is and means lots of people are still in the dark, thousands without power in the north bay this evening. after that earthquake. we want to show you about 7300 people in napa are st

not certain of the actual fault it's on but what happens in the bay area is the strain from the san andreased on a number of structures to the east. these are smaller faults. we're still trying to put together how all of those pieces behave and this is very, very interesting event and i use that warily because it damaged napa and we're worried about all of the people injured there. >> jack, it's chad myers. i have a question for you. can you, for our viewers, describe what a seven-mile deep earthquake feels like compared to a 100-mile deep earthquake? what does the shake feel like? how is it different? >> well, the seven-mile deep earthquake is an earthquake that's occurring in the crust of the earth. so those are sort of our characteristic run of the mill earthquakes. i can just tell you for myself at 3:20 in the morning, i felt about five or six seconds of rolling shaking but that's because i live in san francisco, not up in napa. so what the earth does is it does a very good job of tracking the energy in the crust and for most of the people in the region, that's what you feel. the energy

that is the san andreas fault. that's the big one.y hundred miles, that's where the big shake is going to come from. the fault we were on yesterday is right there. i bet you can hardly see it if you don't have a 65-inch tv at home. that's the size of the fault, the west napa fault, that shook yesterday. so no, not even along the fault itself but still in the fault system itself. because this plate is staying here. this plate here is moving to the north. and every time it moves too much or shakes, then we get that earthquake. the move so far yesterday we found so far the usgs says about four inches at the surface. that's all they could find so far. >> all right. chad myers, i hope you're right, that the big one isn't any time soon. at least people are more conscience and can prepare now. thank you so much, chad. >>> coming up next, an actor takes the ice bucket challenge to a new level. this is orlando jones. pouring a bucket of bullet casings over his head. just what does he hope this will accomplish? i'll speak with him next. wouldn'
