There are no immediate reports of damage after four earthquakes rattled central Oklahoma overnight.
The U.S. Geological Survey reports that an earthquake and a series of aftershocks began about 1:45 a.m. Central Time with a magnitude 3.0 quake centered about 3 miles west-southwest of Chandler, Oklahoma.
That was followed a few minutes later by a magnitude 4.3 quake near Oklahoma City. US Geological Service puts the epicenter of the quake 7 miles east-northeast of Luther, Oklahoma, and about 29 miles east-northeast of Oklahoma City.
At 2:15 a.m. the ground shook again. This time a 2.8 magnitude quake struck about 54 miles east of the capital, followed a minute later by a 3.3 magnitude temblor about 4 miles east of Luther.
