>> most faults -- well, we dont. if it is because we dont even know what fault it is yet. if it is the test. that means at some previous earthquake its come to the surface. >> most earthquakes bebe gin about 5 to 10 miles below a surface. there is not enough confining -- if a fault could open you said you cant have the earthquake, because the earthquake is snape your fingers try snapping your fingers when they open up. and if the fault opens up you wont have shaking. at the surface its not as ...

Is miysterious. it doesnt seem to be moving. we thought it might be that fault but we no it was further north. you get many of these strike set faults. the thought is in the long term, youd initiate the new earthquake boundary which cuts out most of california. these faults align very well with the boundaries of the south. it takes this really weird bend. >> i want to ask you one follow up question. tweeting out in the last 15 minutes or so when that actually happened. we dont know where they ar...

And the automatic system allows it to go in. for a short time, there were two alerts, one from us, one from the tsunami warning center. when we recognized it was there, we cleaned it up. that was not getting rid of an earthquake, by the way. i heard the conspiracy theorists about that its just that we cleaned it up. >> just to clarify additionally, we had been just talking about two faults and so forth. thats still the case. >> right. >> were not -- >> [question inaudible] >> not until we get a ...

Was particularly hard hit. we have reports from california office of emergency services that they -- there seem to be a couple of structure fires going on in ridgecrest, and theyre responding to them. theres also a small community called trona which is even closer to the ruptures, and its on a dry lake bed. we do not have any communication with them yet. it would be a place where theres potentially significant damage. as ive said, were seeing at least two faults involved. this area is characteri...

>> are you on the move? are you going home is your home in ridgecrest as well? >> i live here in ridgecrest, but we have closed down the restaurant for the day because we dont have any power. i mean, theres nothing we can do. >> out of power. i know its hot as well. edgar, thank you so much. lets go back to the seismologist dr. lucy jones for an update. >> we think the main fault was rupturing down towards the southwest, which would have focused the energy towards ridgecrest. but then theres als...

Mapped faults. before im going to talk about an unknown fault i need a geologist to say how does this line up with the ones we know about? >> is this relevant? >> not to us. i think its a psychological issue. if its an unknown fault, we didnt know, it makes it scarier. the reality is we have a lot of little faults that never get names because theyre too small until you get an earthquake. >> was this one particularly strong for that area? >> this earthquake is the largest in the little lake area ...

Quiet abnormal time. this type of earthquake is much more normal. on the long run, we expect earthquakes of this size, even 6.5, long term average is probably once every five or ten years somewhere in southern california. so remember, this is more of what we should be feeling. >> i would say its about the same. this type of earthquake is something that we would expect. theres a tremendous amount. so these types of earthquakes are kind of on the fringes or more active faults.

Faults. so before im going to talk about an unknown fault, i need a geologist to say how does this line up with what we know about. >> is it relevant -- >> not to us. i think its a psychological issue. if its an unknown fault, we didnt know! makes it scarier. the reality is we have a lot of little faults that never get named because theyre too small until you get an earthquake. >> was this one particularly strong for that area? >> this earthquake is the large nest the little lake area in the las...

>> faults -- most faults -- we dont. we dont know what fault it is yet. if it is the little lake fault that is mapped at the surface. its some previous earthquake that has come through to the surface. most earthquakes begin about five to ten miles below the surface. its difficult to get a big earthquake close to the surface. theres not enough pressure. if a fault could open up, you cant have an earthquake. the earthquake is shaking just like snapping your fingers. try to snap your fingers when t...

Is as a -- that area, largest earthquake in 100 years. does that make it unusual? no. from geology, we need to look at millennia to say what is standard. >> [question inaudible] >> were waiting for the picture to show up. its -- theres one level at which its simple. the geologists, presuming theres faults, well be mapping it in detail the next month. >> are they in trucks or helicopters or -- >> trucks. >> we dont have enough money to send helicopters. theyre in trucks. >> the national guard doe...
