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.
It concerns the effects of a massive earthquake in the US states of Missouri, Mississippi, and Louisiana. Largely using the 1811-12 [1] New Madrid earthquake as a base, he depicts the breakdown of infrastructure that would result if an earthquake of equal magnitude were to occur today. The title of the novel is a double-entendre.
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 ...
The 1888 earthquake in Río de la Plata was an intraplate quake, [8] from reactivated faults in the Quilmes Trough, far from the boundaries of the South American plate. With a magnitude greater than 5.0 it was felt "in the cities of Buenos Aires, La Plata and other small towns and villages along the Rio de Plata coastal regions."
A magnitude 5 earthquake may affect 5-15 times larger of an area in the New Madrid Seismic Zone compared to California, largely due to the crustal geology of the two areas.

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 ...
