Arkansas Earthquakes


Arkansans are being asked to join others across the country as they participate in an earthquake drill.

The “Great Central U.S. Shake Out”, is one of many regional earthquake drills being held at 10:20 a.m. on Thursday, Oct. 20. The organization ShakeOut claims to have had over 43 million participants worldwide for the drills in 2015 and hopes for more this year.

Whitney Green, with the Arkansas Department of Emergency Management (ADEM), said a geological fault line that runs under Arkansas makes it important for the state to practice preparedness.

The U.S. Geological Survey reports a 3.8 magnitude earthquake has been recorded near Fairfield Bay.

Police say there are no reports of damage or injuries - although several residents called police to ask about the temblor.

The USGS reports the earthquake was recorded at 4:19 p.m. Wednesday one mile southeast of Fairfield Bay. The area is about 55 miles north of Little Rock.

Geologists say earthquakes of magnitude 2.5 to 3.0 are generally the smallest felt by humans and that damage is not likely with quakes below magnitude 4.0.  

Earthquakes Near Morrilton Get Further Analysis

May 27, 2013

After a series of earthquakes has shaken a region just northwest of Morrilton over this past week, geologists and researchers continue to assess the area. Scott Ausbrooks of the Arkansas Geological Survey says his agency and the Memphis-based Center for Earthquakes Research and Information have installed an additional seismic station to follow activity in the area.

Ausbrooks says that although the cause of the temblors is likely natural, his team is looking at a possible connection with nearby injection wells, used in hydraulic fracturing for natural gas.
