Enola earthquake swarm
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 months.[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.[3] The 2001 Enola earthquake swarm maintained the characteristics of the previous 1982 swarm, with an increase in seismicity without a mainshock-aftershock pattern. The energy released by the mainshock in 2001 was significantly greater than that of the later earthquakes, implying that the mainshock could have led to the triggering of the rest of the sequence.
