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 group was underwater when a 7.2 magnitude earthquake and string of aftershocks shook the country, the videographer said. Watch scuba divers grab onto reef as swarm of underwater earthquakes ...
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 ...
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 ...
The last tsunami warning in the San Francisco Bay Area followed a 9.1 earthquake in Tohoku, Japan that sparked a major nuclear accident at the Fukushima-Daiichi nuclear power plant in March 2011 ...
