The 2011 Arkansas Earthquake was an earthquake that registered 4.7 on the Richter Scale and struck Greenbrier, Arkansas, on 28 February 2011 at 05:00:50 UTC at a shallow depth of 3.8 km.
This earthquake is, to date, the largest of many in what is known as the Guy-Greenbrier earthquake swarm, a series of earthquakes that began in August 2010. The cause of the earthquake remains unknown, although researchers at the University of Memphis believe there is a link between the earthquakes and the production of natural gas.
