An earthquake. and i'm going to ask dr. frankel to join me here in a second. we'll talk act these couple different waves and he'll be able to tell you. he's my seismology guy. there's the train wreck type of wave that you feel where all of the earth's at toms bump into each other and they all just keep moving very fast. that's the first wave, the first shake that you would feel. there's a secondary twhaef you feel that comes through the earth, comes kind of across the crest of the earth. and then there is the large shaking, the love waves that do all kinds of things. they go back and forth. th...

Thing are probably the reason why there's less fatalities. >> tell me about wood structures compared to the haitian structures that were on reinforced concrete. >> unreinforced brick buildings they cannot withstand up-or-down motion or side-to-side motion. wood structures can absorb some of that. wood-frame houses are a much better building material to use in an earthquake-prone area. >> we'll get back to this. this is going to show where the wave, why the wave was generated and where it's going. >> yep. >> something he told me a little bit ago, earthquakes don't kill people, buildings keep pe...

>> aftershocks. >> with an 8.8, couldn't that move other plates around to maybe cause another one? >> there's also a possibility of what we called triggered cognis ti, but it's hard to tell. >> plenty of aftershocks. angela, go ahead and play this because we'll figure out what happens. >> here's the sea floor and it's a ducking plate and the the rupture of that plate moving up. >> so the rupture pushes -- >> pushes the sea floor up. >> pushes is sea floor up. >> and that pushes the water -- of course there's water and it's got to go somewhere if the se floor goes somewhere. that water travels ...

"we are closely monitoring the situation including the potential for a tsunami. ou...

Emergency vehicles in there. >> rob, let me ask you this. when you have a situation that you've got an earthquake and a tsunami that occurs after, how much time in between do the folks living there have? >> depends on how far you are from the quake. that village probably less than 00 miles from the epicenter so you've got a twhaef travels at 500 miles an hour so you're got ten minutes. >> basically a one-two punch. >> you feel it and here comes the wave. if anybody lived close tho that shoreline, they may have been washed away by the tsunami itself. these are the first pictures we're getting a...
