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.
Earthquakes in the New Madrid and Wabash Valley seismic zones from 1974 to 2002, with magnitudes larger than 2.5. The zone had four of the largest earthquakes in recorded North American history, with moment magnitudes estimated to be as large as 7 or greater, all occurring within a 3-month period between December 1811 and February 1812.

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 ...
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.
