UPDATE 10:30AM: Some people may wonder how a 5.4 quake in the Midwest can be felt much farther away than those that take place along the West Coast. Here is an explanation I found on Brendan Loy’s blog the IrishTrojan.com:

If you’re a Californian wondering how on earth something a puny as a 5.2 quake (or “temblor,” as you guys say out there) could be felt so strongly from places as far afield as Chicago and Knoxville, it’s because, as explained here, “seismic waves in the East travel farther and pack more destructive punches.” The exact reason for this phenomenon is a topic of much debate among scientists, but “one explanation is that eastern geology is older and simpler, with fewer faults in the ground to slow the travel of quake waves.”

Earthquake History of Illinois. | Information on the Madrid Fault line

December of 1811, the largest earthquake ever recorded in American History occurred on the New Madrid Fault, near New Madrid, Missouri. The magnitude of the New Madrid quake was estimated to be of 8.0 or higher on the not yet invented Richter scale. Large areas sank into the earth, new lakes were formed, and the Mississippi River changed its course due to the earthquakes.
