We have just had two earthquakes today located about 125 miles east of St. Louis. The first one was 5.2 about 4:37 AM CST and the second one 4.5 about 10:15 AM CST. One of the guys I work with said he talked to somebody that has family near the epicenter and they have had 4 or 5 smaller ones in between those two. I am not sure if the fault line is on the New Madrid line. This is the fault line that had several violent quakes during December 1811 through February 1812. Those were felt in 27 states, mad the Mississippi river flow backwards, formed several lakes in the area, and rang church bells in Philadelphia.
Today's quake (the first one at least) was detected as far north as the Dakotas and as far south as Atlanta.
