It that were feeling in l.a. kind of roughly? >> the magnitude -- it does not depend on location. it is a 7.1 period. there is no location to that. to describe what we feel we talk about intensity. and it looks like it was intensity 3 to 4 in the los angeles area, depending on exactly where you were. >> from those two again, the aftershock sequence is not a surprise. it is vigorous, but its in line with what weve seen before. maybe not anticipating it, but thats also within the ballpark. >> in c...

Day, its a very broad wave so it will bring in a lot of water with it. >> right. and i guess the speed in which the wave hits is key, correct? >> it is. it depends on the shorelines configuration, it can -- quite variable can be the effects, right. >> and robert, you said that the earthquake they had a day or so ago in that region, seven something magnitude foreshadowed this one which was a gigantic one of 8.9 magnitude. is there a possibility of an even larger earthquake after this? >> theres a...
