Six small earthquakes have been recorded in the Luther and Jones areas in central Oklahoma.
The quakes range from a preliminary 1.8 magnitude recorded by the Oklahoma Geological Survey at 1:48 a.m. on Sept. 1 to a magnitude 3.1 recorded by the U.S. Geological Survey at 7:46 p.m. Aug. 31. No damage or injuries have been reported – but several people reported on the Oklahoma Geological Survey Web site that they heard a rumbling sound, felt shaking and saw small items shaking on shelves.
The earthquakes were clustered in an area about 30 miles northeast of Oklahoma City. The most recent was a 2.5 magnitude quake recorded at 4:17 a.m. Sept. 1.
Researchers say quakes of 2.5 to 3.0 magnitude quakes are typically the smallest felt by humans.
