The New Madrid Seismic Zone
The New Madrid Seismic Zone is the most active earthquake zone east of the Rocky Mountains and spans southeastern Missouri, northeastern Arkansas, western Tennessee, western Kentucky, and southern Illinois.
Between 1811 and 1812, the New Madrid Fault experienced some of the largest quakes in history. And although they originated in the Mississippi Valley, they rang church bells in Boston and shook New York City — over 1,000 miles away.
Even then-President James Madison and his wife Dolley reportedly felt shaking at the White House.
After one particularly large rupture in the fault, the mighty Mississippi River was forced to run backward for several hours, devastating acres of forest and creating 2 temporary waterfalls.
Fortunately the Mississippi Valley was sparsely populated back then.
Today millions of people live in densely populated urban areas like St. Louis and Memphis, making this zone one of the biggest concerns for the Federal Emergency Management Agency.
Those two small quakes are just a reminder that the New Madrid Seismic Zone may rupture at any moments. Be prepared!
One of the strongest earthquakes in the nation made the Mississippi river run backwards.
