Magnetic potential map of the Reelfoot Rift. The New Madrid Seismic Zone (NMSZ), sometimes called the New Madrid Fault Line, 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.
Eastern Tennessee Seismic Zone. The Eastern Tennessee Seismic Zone (ETSZ), also known as the East Tennessee Seismic Zone and the Southern Appalachian Seismic Zone, is a geographic band stretching from northeastern Alabama to southwestern Virginia that is subject to frequent small earthquakes. The ETSZ is one of the most active earthquake zones ...
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.
Tennessee’s middle region has only experienced a handful of 2.5 magnitude or higher earthquakes between 1924 and 2024, including Murfreesboro in 1997 and Franklin in 2001, according to the USGS ...
The capital city of Arkansas, Little Rock, would also face damage. A major natural gas pipeline is located near the fault, and could be devastated by any such earthquake. Tennessee and Mississippi would possibly be affected as well. In 2006, a letter to the Seismological Research Letters indicated the possible existence of a fault at Marianna.
To map the subduction zone, researchers at sea performed active source seismic imaging, a technique that sends sound to the ocean floor and then processes the echoes that return. The method is ...
San Andreas Fault System (Banning fault, Mission Creek fault, South Pass fault, San Jacinto fault, Elsinore fault) 1300: California, United States: Dextral strike-slip: Active: 1906 San Francisco (M7.7 to 8.25), 1989 Loma Prieta (M6.9) San Ramón Fault: Chile: Thrust fault: Sawtooth Fault: Idaho, United States: Normal fault: Seattle Fault ...
150–160 earthquakes [1] The Guy-Greenbrier earthquake swarm occurred in central Arkansas beginning in August 2010. [2] The epicenters of earthquakes in the swarm showed a linear distribution, with a clear overall shift in activity towards the southwest with time, [3] and the largest event in the swarm was the 2011 Arkansas earthquake, at 4.7 ...
