Small earthquake recorded in northwestern Oklahoma

December 15, 2018

WOODWARD, Okla. (AP) — The U.S. Geological Survey reports a small earthquake has been recorded in northwestern Oklahoma.

The U.S.G.S. recorded the magnitude 3.1 quake at 12:09 a.m. Saturday about 35 miles (56 kilometers) east of Woodward and about 97 miles (156 kilometers) northwest of Oklahoma City.

No injuries or damage are reported. Geologists say damage isn’t likely in temblors below magnitude 4.0.

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. Earthquakes in Kansas, Texas and other states have also been linked to wastewater injection.

Oklahoma regulators have directed several producers in the state to close injection wells and reduce volumes in others.
