You wrote: "But the strange part, is I have never heard of one earthquake in that area." Well, it's coming. The "New Madrid" fault (in Missouri) is going to pop someday. I felt it (a small one, about a 3.0) when I was in Quincy, IL in late 1968 or early 1969. The geological record indicates that there was a BIG one (8.0?) on the 'New Madrid' fault about 350 years ago. In '68 or '69 they said that the one 350 years ago (a) moved the Mississippi and (b) if it happened then ('68-'69) that there would not be a stone left upon a stone in St. Louis. St Louis then began to implement appropriate seismic standards in new construction. When I moved out here I took a 'History of California' course and the instructor said that some of the Indian dialects were similar to those in the Midwest. I figured that the Midwest Indians packed up after that big one.
