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.
In 1811–1812, a series of large earthquakes occurred on the rift, causing great devastation. [ 2 ] Martin and Hough postulated three different plausible events, a north-northwest rupture from Henson Lake to Charleston, a northeast rupture on the western boundary faults of the Reelfoot Rift, or north-northeast or north-northwest rupture within ...
A 3D printed model, created by Dr. Christodoulos Kyriakopoulos with University of Memphis’ Center for Earthquake Research and Information, demonstrates the New Madrid 1812 earthquake on Thursday ...
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.
This area of the Mississippi River, from just east at "Island Number Ten" around to the town of New Madrid, Missouri, was the site of a Civil War battle from February 28 to April 8, 1862, the Battle of Island Number Ten. Due to its highly productive soil in the river's floodplain, Kentucky Bend was developed as a major cotton-producing area ...
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 discoveries of Earth's tectonic plates, [1] seismotomography imaging technique, [2] observations using space satellites from outer space, [3] artificial intelligence (AI)-based ...
