New Madrid fault and earthquake-prone region considered at high risk today. The 1811–1812 New Madrid earthquakes were a series of intense intraplate earthquakes beginning with an initial earthquake of moment magnitude 7.2–8.2 on December 16, 1811, followed by a moment magnitude 7.4 aftershock on the same day. Two additional earthquakes of ...
The New Madrid seismic zone (NMSZ), sometimes called the New Madrid fault line (or fault zone or fault system), is a major seismic zone and a prolific source of intraplate earthquakes (earthquakes within a tectonic plate) in the Southern and Midwestern United States, stretching to the southwest from New Madrid, Missouri.
An undated photo from the US Geological Survey depicts a landslide trench and ridge in the Chickasaw Bluffs, east of Reelfoot Lake, Tennessee, resulting from the 1811 to 1812 New Madrid earthquakes.
What are the New Madrid earthquakes of 1811-1812? The New Madrid earthquakes of 1811 and 1812 were some of the largest earthquakes recorded in U.S. history, according to USGS.

Geologists estimate that similar New Madrid Seismic Zone earthquakes like the ones in 1811 and 1812 have a 7–10% chance of reoccurring within the next 50 years.
This area of the Mississippi River, from just east at "Island Number Ten" around to the town of New Madrid, Missouri, was the site of a Civil War battle from February 28 to April 8, 1862, the Battle of Island Number Ten. Due to its highly productive soil in the river's floodplain, Kentucky Bend was developed as a major cotton-producing area ...
"The strongest earthquakes in the last few years have come from the Wabash Valley Fault, which needs more investigation." [4] Numerical modeling indicates that stress transfer following the 1811–1812 New Madrid earthquakes may be loading faults in the Wabash Zone. [6] Notable modern earthquakes in this zone include: June 10, 1987, magnitude 5.0
