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 similar magnitude followed in January and February 1812.

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.
Massive earthquakes have rocked the New Madrid Seismic Zone, which includes Memphis. ... The USGS estimates that there’s a 7% to 10% chance the NMSZ would get a repeat of the 1811-12 earthquakes ...
Aftershocks from devastating earthquakes in the 1800s near the Missouri-Kentucky border and in Charleston, South Carolina, may still be occurring, a study found.
Locations of quakes magnitude 2.5 or greater in the Wabash Valley (upper right) and New Madrid (lower left) Seismic Zones. The Wabash Valley seismic zone (also known as the Wabash Valley fault system or fault zone) is a tectonic region located in the Midwestern United States, centered on the valley of the lower Wabash River, along the state line between southeastern Illinois and southwestern ...
New Madrid was the epicenter of the powerful 3-month 2,000-earthquake 1811–1812 New Madrid earthquakes. In 2003, the U.S. Geological Survey predicted that another major earthquake will happen in New Madrid within the next 50 years, [ 18 ] a theory that was rejected by the geophysicist Seth Stein in his 2010 book Disaster deferred: how new ...
Examples of intraplate earthquakes include those in Mineral, Virginia, in 2011 (estimated magnitude 5.8), Newcastle, New South Wales in 1989, New Madrid in 1811 and 1812 (estimated magnitude as high as 8.6), [6] the Boston (Cape Ann) earthquake of 1755 (estimated magnitude 6.0 to 6.3), earthquakes felt in New York City in 1737 and 1884 (both ...
