in the world in the last 250 years was in the middle of Missouri / Arkansas, Tennessee, Kentucky area.
While not as well known for earthquakes as California or Alaska, the New Madrid Seismic Zone (NMSZ), located in southeastern Missouri, northeastern Arkansas, western Tennessee, western Kentucky and southern Illinois, is the most active seismic area in the United States, east of the Rocky Mountains. The area includes major cities such as Memphis, Tennessee, St. Louis, Missouri, Little Rock, Arkansas and Evansville, Indiana. Every year hundreds of small earthquakes occur in the NMSZ, however, most are too small to be felt by humans and can only be detected by sensitive instruments.
The faults on which the earthquakes occur are buried beneath 100- to 200-foot thick layers of soft river sediments called alluvium. Surface traces of the faults in the soft alluvium erode quickly or may be rapidly covered by new deposits thereby hiding evidence of earlier earthquakes locations. In places like California, where rocks are at or near the ground surface, faults are much easier to study because they can be readily measured and analyzed. Since the faults in the NMSZ are not expressed at the surface, they are not as well understood and are more difficult to study.
History
The NMSZ is famous for a series of three major earthquakes (believed to have been magnitude 7.0 or larger) which occurred in the two month period between Dec. 16, 1811, and Feb. 7, 1812. In addition, hundreds of moderate earthquakes (magnitude 5.0-6.5) and thousands of smaller (magnitude 5.0- 4.0) earthquakes occurred in between the larger earthquakes and continued shaking the area for several months. These earthquakes were felt and recorded in personal journals as far away as Louisville, Kentucky and Cincinnati, Ohio.
The very heart of the "bible belt"... of course I think they all secretly worship the devil ( in the form of Trump ) so maybe Ghooliani has a valid point.
