Is the New Madrid Fault Becoming Active Again?
The New Madrid Fault in Missouri was the site of one of America's largest ever series of earthquakes. Exactly 200 years removed from the quakes that caused the Mississippi River to flow in reverse, the region in Southeastern Missouri has been hit again with a 4.0 quake earlier this week.
The epicenter of this week's quake was 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.
Only minor damage was reported, such as items falling from shelves, broken windows, minor cracks in walls and sidewalks.
