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.
In 1812, this area of the river was highly disrupted and was reported to even flow backward because of the 1811–1812 New Madrid series of earthquakes, some of the most powerful ever felt in the United States. [8]
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.
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 ...
