Theyre saying there is potential for this to spread beyond the immediate ridgecrest area. >> yes. and that is a curious question. and typically what you can expect is between two and three times the distance extending from the epicenter. just because this area is very seismically active. there are all these tiny little faults, some of them intersecting, so theyre perpendicular. and thats kind of what were seeing across this region. theyre saying intersectioning fault lines. and this particular o...

Thats charactategorized by int. we havent had that in parts of world. these are worldwide earthquakes. take a look at that, how many do we get, about 15 of 7.0, this is certainly not unprecedented. victor, you see the colors. 6.4, the 7.1, just to the northwest. seven miles apart. then all of the dots you see, those are aftershocks. the orange ones and red ones means they happened in the last six hours. heres the forecast, as far as what were expecting as additional earthquakes, aftershocks. not...

Ground. rather than naming each piece separately its called the little lake fault system. these are -- >> the length of the fault itself has been defined by the 7.1 earthquake. >> no. we dont know. if you look at the map we can see. one of the things we can do if we got a break and found stuff. we could pull out -- well try to get out the state geology map. but notice theres a little string of -- >> and it was not a through going fault. it was pieces through here. and we have pieces further up. ...

Difference and itll be that much bigger. if a 7.8 on the san andreas will be a lot bigger. but consider this is only 10% of the san andreas so its a pretty big earthquake. >> going from memory, though, the earthquake we had was like easter sunday. >> okay on easter sunday 2010, april 4th, a magnitude 7.2, i havent been including that because it wasnt in california. the rupture was completely within mexico. so, yes, we felt it in probably a similar sort of distance -- well, it didnt feel quite as...

The san andreas fault. that fault has nothing to do with this. thats what the scientists told us earlier. seismologist who has been keeping us updated was saying this is a con vvergence of different faults. faults that are spreading. every earthquake is an opportunity to learn what works and what doesnt. everything about building structure, warning systems which did work. and also the cause of the quake themselves. scientists have a will the of data to look over and theyll be poring over it. as ...

Of questions in terms of the ground motions that are radiated from faults as faults break to the surface like this. there is actually indications that the ground motions are lower than they might be expected from ruptures that are buried. if you remember dr. jones talking about the northridge earthquake, that was a buried fault. and it was very energetic, even though the magnitude was 6.7, it was incredibly strong shaking. this earthquake its going to be interesting to see. its a 7.1, but the gr...

Thats associated with a larger event, with a magnitude 7.1. >> and the road appears to be -- >> yeah, its down towards the southeast end of this magnitude 7.1 sequence. closer to trona? >> yes, closer to trona. >> right here. >> and we suspect that the fault is actually ruptured much further to the northwest. that is the area thats on the china lake naval weapons station. presumably theyre not able to get out there tonight. we are obviously seeing displacements that are associated with this eart...

Aftershocks occurring every several minutes or so. >> yeah. many of the seismologists there at corral tech saying theres a in 10 chance of an even stronger quake over the next few days. >> caller: thats correct. you never know if this is the biggest one yet or if there could possibly be a larger one. about 1 in 10 chance is the probability. you know, based upon other earthquakes that have occurred in the past. >> weve heard so much about the san andreas fault. what do we know about this fault? w...

The last 24 hours. and so you can see this basically happened at the end of the zone that moved previously. were seeing a few earthquakes way up to the northwest. we know the faults extending that far. it may welcome back down to where the 6.4 was. we can guess at the size of the fault. from the magnitude. 40, 50 kill mometers. something like 30 miles long. what were seeing is about 15 miles. so probably involving the lower part too. >> okay. briefly, actually when this occurred we were on a cal...

They move with respect to each other and if they move like this it is right lateral and if it moves like this, its left lateral. [reporter question] >> san andreas is a left lateral, dip slip moving up the mountains. in general, the faults, many parts of california we see this strike slip motion and what it is leading to is gradually extending -- it isnt pushing us up or down, but it is sort of moving sideways and stretching out parts of the state. >> reporter: can you talk a little bit about th...
