On tuesday a magnitude 4.0 occurred on the New Madrid seismic zone a few miles north of New Madrid, 3.1 miles deep.
An excerpt from an AP article reads;
Just days after the 200th anniversary of a series of massive earthquakes in southeast Missouri, residents woke up Tuesday to a rumbling reminder that they live in one of the continent’s most active seismic areas.
The U.S. Geological Survey said the epicenter of a magnitude 4.0 earthquake at 3:58 a.m. was located near the town of East Prairie, Mo., roughly midway between St. Louis and Memphis. Several people in five states — Missouri, Illinois, Arkansas, Kentucky and Tennessee — felt the quake, along with scattered people in four others, as far away as North Carolina and Georgia, according to responses to the U.S. Geological Survey website.
