EDMOND, Okla. – The U.S. Geological Survey has recorded two earthquakes that struck near a central Oklahoma town.
Both temblors hit just east of the Oklahoma City suburb of Edmond early Sunday. The first quake had a preliminary magnitude of 3.7 and struck at 2:12 a.m. The second quake, with a preliminary magnitude of 2.9, followed soon after, hitting at 2:20 a.m.
There were no immediate reports of injury or severe damage.
Thousands of quakes have struck Oklahoma in recent years, many linked to the underground injection of wastewater from oil and natural gas production. Researchers have also linked earthquakes in Kansas, Texas and other states to wastewater injection.
Several oil and gas producers have been directed to close wells and reduce injection volumes in others, including two near the recent temblors.
