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.
The New Madrid Seismic Zone (NMSZ), sometimes called the New Madrid Fault Line, 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 system was responsible for the ...
The New Madrid Fault Zone is named for the city of New Madrid in the Bootheel. This fault zone is entirely hidden beneath the deep alluvial deposits of the Mississippi embayment.

The Eastern Tennessee Seismic Zone (ETSZ), also known as the East Tennessee Seismic Zone and the Southern Appalachian Seismic Zone, is a geographic band stretching from northeastern Alabama to southwestern Virginia that is subject to frequent small earthquakes. The ETSZ is one of the most active earthquake zones ...
An 1800 map shows a 'Redfoot River' in the area near the Lake, a possible misspelling of the name from Henry Rutherford's 1785 survey. From Low's Encyclopaedia. According to the United States Geological Survey, Reelfoot Lake was formed in northwestern Tennessee when the region subsided during the 1811–12 New Madrid earthquakes, which were centered around New Madrid, Missouri.
