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.
[2] These events resulted in a linear cumulative seismicity rate with a b value of nearly 1.0, which is an unusual result as compared to swarms other places.
These earthquakes have not been linked to the more well known New Madrid Seismic Zone.
