23 quakes strike central Arkansas in 36 hours

[DearAbby]

The Earth is shaking in central Arkansas.

Almost two dozen earthquakes of magnitude 2.3 or greater have struck the region since midnight Wednesday, the U.S. Geological Survey reports.

The largest of the temblors, at 4.3 magnitude, hit at 2:13 a.m. Friday. It followed a 4.0-magnitude event at 11 p.m. Thursday.

No damage has been reported from any of the quakes, all centered near the town of Greenbrier in Faulkner County, CNN affiliate KARK reports. Residents reported hearing a boom at the time of Friday morning's quake, KARK reported.

The earthquake swarm is reminiscent of a swarm that hit the area last fall. More than 500 were recorded in less than a month.
