Two moderate earthquakes have been recorded in central Oklahoma.
The U.S. Geological Survey reports a 4.5 magnitude quake at 1:12 p.m. Monday and a 4.0 magnitude quake at 12:49 p.m. - both about three miles northeast of Crescent or about 35 miles north of Oklahoma City.
The Logan County Sheriff's Office and officials at Crescent City Hall say there are no reports of damage or injury.
The Oklahoma Corporation Commission recently announced plans to place more than 200 oil and natural gas wastewater disposal wells under scrutiny as it investigates whether the wells are triggering earthquakes in the state. The Oklahoma Geological Survey issued a report in April saying it's "very likely" most of the state's recent earthquakes were triggered by the injection of wastewater from oil and gas drilling operations.
