Arkansas, Oklahoma Record Minor Earthquakes

April 12, 2010

The U.S. Geological Survey has recorded another earthquake in central Oklahoma, and an additional one in central Arkansas as well.

A 3.2 magnitude earthquake was recorded at 7:42 a.m. April 8 about two miles southwest of Jones – about 10 miles northeast of Oklahoma City. No injuries are reported.

There have now been 47 earthquakes and aftershocks recorded in Oklahoma this year with 40 of those measuring at least a 2.0 magnitude. Quakes of magnitude 2.5 to 3 are generally the smallest felt by people.

Geological survey officials say the earthquakes are part of a phenomenon called a swarm and do not appear to present a serious threat.

A small earthquake has rattled an area near Greenbrier in central Arkansas.
