Enola earthquake swarm - Wiki slovník

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 swarm created damage and in May 2001 the swarm increased activity with the notable 4.4 earthquake. The after shocks exceeding a magnitude of 2.0. These earthquakes have not been linked to the more well known New Madrid Seismic Zone. ^[4]
