3.6 Magnitude Earthquake in Arkansas

April 8, 2011

The U.S. Geological Survey has recorded a magnitude 3.6 earthquake near Greenbrier in central Arkansas.

No injuries or damage is reported.

The quake was recorded at 9:34 p.m. about two miles northeast of Greenbrier. The site is about 35 miles north of Little Rock.

There have been more than 1,000 quakes in the area since September – including the largest quake to hit the state in 35 years – a magnitude 4.7 on Feb. 27.

Two natural gas companies have shut down two injection wells in the area as researchers study whether the operations are connected to the earthquakes. Oklahoma City-based Chesapeake Energy and Clarita Operating of Little Rock have shut down the wells.
