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.
Browning received notoriety for his erroneous prediction that a major earthquake would occur on the New Madrid Fault around December 2 and 3, 1990. This prediction had no scientific legitimacy, [ 1 ] : p. 3 and was largely ignored by credentialed seismologists, who thought it would give the prediction undeserved attention if they were to debunk ...
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 ...

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 ...
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 ...
That year brought the latter part of series of earthquakes along the New Madrid Seismic Zone so strong that they temporarily reversed the flow of the Mississippi River. Now the comet’s return ...
