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 ...

Historical earthquakes is a list of significant earthquakes known to have occurred prior to the early 20th century. As the events listed here occurred before routine instrumental recordings — later followed by seismotomography imaging technique, [1] observations using space satellites from outer space, [2] artificial intelligence (AI)-based earthquake warning systems [3] — they rely mainly ...
A series of more than 1,000 earthquakes struck the area in 1811 and 1812. The New Madrid earthquakes were the strongest non-subduction zone earthquake in the United States. A request dated January 13, 1814, by the Territorial Governor William Clark, asked for federal relief for the "inhabitants of New Madrid County." [citation needed]
