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 1812 San Juan Capistrano earthquake, also known simply as the Capistrano earthquake or the Wrightwood earthquake, [6] occurred on December 8 at 15:00 UTC (07:00 local time) in Alta California. At the time, this was a colonial territory of the Spanish Empire .
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 researchers found that approximately 30% of all earthquakes from 1980 to 2016 near the Missouri-Kentucky border, all magnitude 2.5 or greater, were likely aftershocks from the three major ...
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 ...

These two earthquakes are considered a regional earthquake sequence, rather than a main shock and aftershock. [ 11 ] The magnitude 5.7 Little Skull Mountain (LSM) earthquake the following day, June 29, 1992, at 10:14 UTC near Yucca Mountain , Nevada, is also considered part of the regional sequence and may have been triggered by surface wave ...
