3.2 magnitude earthquake rattles parts of northwest Oklahoma

Posted October 14

— The U.S. Geological Survey says an earthquake has shaken parts of northwestern Oklahoma.

Geologists say the 3.2 magnitude quake was recorded at 6:50 a.m. Friday about 9 miles east-northeast of Mooreland in Woodward County. The quake was recorded at a depth of less than 2 miles.

No damage or injuries were immediately reported following the earthquake. Geologists say earthquakes of magnitude 2.5 to 3.0 are generally the smallest felt by humans and that damage is not likely in quakes below magnitude 4.0.

An increase in magnitude 3.0 and stronger earthquakes in Oklahoma has been linked to the underground disposal of wastewater from oil and natural gas production. State regulators have ordered some disposal wells to be permanently shut down and others to reduce the volume of wastewater they dispose.
