Oklahoma Once Again Rattled by Earthquake Swarm

The U.S. Geological Survey says at least four earthquakes have rattled central Oklahoma, including a 4.3-magnitude temblor near Langston.

The earthquake struck shortly after noon on July 12 about five miles southwest of Langston. Earlier, a 3.2-magnitude quake was recorded about 6:30 a.m. in about the same area near Langston. No damage or injuries were reported following either quake.

The USGS says two other quakes were recorded Saturday near Guthrie. The first, a 2.9-magnitude quake, struck shortly before noon about five miles east of Guthrie. A second 3.0-magnitude quake was recorded in the same area at about 12:30 p.m.

Geologists say quakes of magnitude 2.5 to 3.0 are generally the smallest that are felt by humans and that damage is not likely in quakes of magnitude 4.0 or lower.
