The state of Oklahoma records one of the biggest earthquake swarms in its history.  Analysts say at least 22 quakes were reported in 13 just hours.

According to The Weather Channel, a 4.7-magnitude tremor was followed 30 seconds later by a 4.8-magnitude quake.

Both were centered in a sparsely populated area about 20 miles northwest of Fairview, Oklahoma, about 97 miles northwest of Oklahoma City.  The quakes struck at depths of 2.1 and 3.7 miles below the surface.

The twin earthquakes occurred at 10:27 p.m. CST Wednesday night and were felt from central Kansas to southern Oklahoma and the eastern Texas panhandle, including in Wichita, Kansas, and the Oklahoma City metropolitan area.
