A 3.9-magnitude earthquake was reported Tuesday night in Grant County, the U.S. Geological Survey reported.
The earthquake happened at 7:39 p.m. Its epicenter was located about eight miles north, northwest of Medford, 36 miles north of Enid and 101 miles north of Oklahoma City.
The earthquake was about three miles deep. This is one of several earthquakes reported near Medford in the last week.
Due to the volume of earthquakes above a 3.0 magnitude, the Oklahoma Corporation Commission's Oil and Gas Conservation Division on Tuesday called for disposal wells injecting into the Arbuckle formation to reduce injection volume.
No immediate reports of injury or damage were reported.
