PAWNEE, Okla. (AP) — The U.S. Geological Survey reports two small earthquakes in northern Oklahoma.

A 3.2 magnitude quake was recorded Wednesday near Pawnee, about 70 miles northeast of Oklahoma City and a 3.0 magnitude quake was recorded near Watonga, about 50 miles northwest of Oklahoma City.

No injuries or damage are reported and geologists say damage is not likely in earthquakes below magnitude 4.0.

Thousands of earthquakes have been recorded in Oklahoma in recent years, and many have been linked to the underground injection of wastewater from oil and natural gas operations.

Regulators have directed oil and natural gas producers to close some disposal wells or reduce the volume of fluids they inject.
