Magnitude 4.0 quake rattles Oklahoma

STROUD, Okla. — The U.S. Geological Survey reports that three earthquakes hit Oklahoma Wednesday.

The biggest, a magnitude 4.0 temblor near Stroud.

Two smaller quakes were also recorded. A magnitude 2.7 quake struck near Fairview and a magnitude 2.5 temblor hit near Mooreland.

No injuries or damage were reported.

Geologists say damage is not likely in earthquakes below magnitude 4.0.

Thousands of earthquakes have been recorded in Oklahoma in recent years.

Many quakes 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.
