So the epicenter of the earthquake was in Bellmont, Illinois, which is on the 127 miles east of St. Louis. The quake measured 5.2 on the Richter scale. The aftershock this morning at 10:14 was measured at 4.5. According the the St. Louis Post-Dispatch, the quake was caused by the moving apart of 2 tectonic plates along the New Madrid fault, though it apparently originated from a spur known as the Wabash Valley Seismic Zone. Rather than just continuing to quote the Post-Dispatch, I'll link the article here.
Barb just informed me that she heard that we may be getting aftershocks for a couple of days. Terrific.

On the news they were saying that we may have aftershocks for a month. This is just crazy, but I am glad that everyone is fine.
