particular earthquake occurred to past earthquakes in other parts of the state, where it is in southern california, could it be a safer area where you won't see as much damage-potentially as you could in other areas. >> well, at least one thing just to my mind is the new madrid fault in the midwest, in the early 1800s, there was a spectacular quick in kentucky, southern illinois, southeast missouri, we're talking about an area south of st. louis and west of paducah, kentucky. we don't associate that area with earthquakes. there's a fault there. at some point it's likely to repeat itself. great concern in that area. because of building construction and codes. in southern california, the legislators and general contractors, they build to a different standard and that protects people there. much more so than what could happen in areas like memphis.
