chad meyers is here. what do we know they might be seeing later today? >> we have seen three big aftershocks, and the latest was a 5.7. there is australia. we know all about that, and the wiggles live there and all of that. here is new zealand down here, all part of this pacific ring of fire. the entire ring of fire in most spots the reason why some of these islands and valleys and places exist in the first place. let's take to you what we're talking about. here's the city here of christchurch and right there, the earthquake only about three miles down into the crust of the earth. very shallow, so whatever shook got all of the way to the surface, violent shaking. six months ago, there was a 6.0, 7.0 quake. about 40 miles to the west, and far enough to the way there wasn't the violent shakes like we had last night.
