RENFROW, Okla. (AP) — The U.S. Geological Survey reports three small earthquakes have been recorded in northern Oklahoma.
The largest of the quakes recorded late Friday and early Saturday has a preliminary magnitude of 3.2 and struck at 11:03 a.m. Saturday near the town of Renfrow, 103 miles (166 kilometers) north of Oklahoma City.
No injuries or damage are reported.
The survey also recorded a magnitude 2.7 quake near the town of Byron at 7:54 a.m. Saturday and a magnitude 2.6 temblor at 11:51 p.m. Friday northwest of Guthrie.
Thousands of earthquakes have been recorded in Oklahoma in recent years, with many linked to the underground injection of wastewater from oil and natural gas production operations. Oklahoma regulators have directed oil and gas producers to close some wells and reduce injection volumes in others.
