aka: New Madrid Seismic Zone
The New Madrid Fault, also called the New Madrid Seismic Zone, is actually a series of faults, or fractures, at a weak spot in the earth’s crust called the Reelfoot Rift. It lies deep in the earth and cannot be seen from the surface. The fault line runs roughly 150 miles from Arkansas into Missouri and Illinois. In 1811–1812, it was responsible for the most violent series of earthquakes in the history of the continental United States (though there have been larger individual earthquakes). Scientists predict that another large earthquake is due which could inflict great damage to Arkansas as well as up to half the nation. The New Madrid seismic zone runs roughly northeast from Marked Tree (Poinsett County). …
