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. The New Madrid fault system was responsible for the ...
New Madrid fault and earthquake-prone region considered at high risk today. 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 ...
Al-Shukri believes that the fault was created 5,000 years ago. Previously, the predicted earthquake damage Marianna, Arkansas might receive from the more distant New Madrid Fault suffering a 7.0 earthquake was 100% architectural and content damage, half of all bridges suffering some damage, 2,955 displaced residents, and loss of phones and ...
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 on the moment magnitude scale.

Permian - Cambrian. Meers Fault is a fault in Oklahoma that extends from Kiowa County to Comanche County. It is marked by a 22–26 kilometers (14–16 mi) long conspicuous fault scarp but the fault extends beyond the ends of this scarp. The Meers fault is part of a group of faults that lie between the Anadarko Basin and the Wichita Mountains.
The Enola earthquake swarm was a series of earthquakes in 2001 that centered on Central Arkansas. It follows the earthquake swarms of Arkansas in the 1980s, and predates the Guy-Greenbrier earthquake swarm that started in 2010. [1] The earthquake sequence started with a 4.4 magnitude main shock and 2,500 earthquakes followed in the next 2 ...
Ramapo Fault. The Ramapo Fault zone is a system of faults between the northern Appalachian Mountains and Piedmont areas to the east. [1] Spanning more than 185 miles (298 km) in New York, New Jersey, and Pennsylvania, it is perhaps the best known fault zone in the Mid-Atlantic region, and some small earthquakes have been known to occur in its ...
