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. The New Madrid fault ...
The New Madrid seismic zone located in the midcontinental United States is a region of concentrated seismic activity. This zone is within the Reelfoot Rift, a failed rift trending northeast. Faulting within the rift occasionally causes small to moderate earthquakes.

That's exactly what happened in the 1811 and 1812 earthquakes, when three earthquakes estimated to be between 7.0-8.0 magnitude rocked New Madrid.There was structural damage as far as Cincinnati ...
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 ...
Pressure on the fault where the 1811–1812 New Madrid earthquakes occurred was believed to be increasing, [23] but a later study by Eric Calais of Purdue University and other experts concluded the land adjacent to the New Madrid fault was moving less than 0.2 mm (0.0079 in) a year, increasing the span between expected earthquakes on the fault ...
