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. Many of ...

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.
This graph shows the earthquakes that have been detected on the edge of the Hanford Reach National Monument starting Sept. 21. The largest, those with magnitude 2.0 to 3.0 are shown in green.
