I believe the New Madrid fault is in Missouri.
It actually cuts across of number of states which include Tennessee and
Missouri. Mind you, it's not as big as the fault systems out in the
western United States.

I don't know if it was associated with the New Madrid fault, but sometime
in the summer of either 1988 or 1989, I can remember feeling an earthquake
in Northern Indiana. It was during the day, and I happened to be reading
on my bed on the seconrd story of our home. It wasn't very strong quake,
but enough to give a quick uneasy jolt that lasted a second or two. I'm
not sure where the epicenter was located.

used historical to monitor earthquake activity?
