Earthquakes Rattle Northwest Oklahoma

(From CBS News)

An earthquake rattled northwest Oklahoma early Monday morning – at least the fifth quake to hit the region since Saturday. The U.S. Geological Survey says the temblor on Monday measured a 4.3 magnitude and was centered 17 miles southwest of Perry, which is about 80 miles west of Tulsa.

A magnitude 4.6 earthquake shook Oklahoma on Saturday and was also felt in neighboring Kansas and Missouri, according to the USGS.

The quake on Saturday was one of four earthquakes recorded in northwest Oklahoma on Saturday morning. Garfield County Emergency Management Director Mike Honigsberg said there are no immediate reports of injury or serious damage following the quakes.

Many of the thousands of earthquakes in Oklahoma in recent years have been linked to the underground injection of wastewater from oil and natural gas production. State regulators have directed several producers to close or reduce volumes in some wells.
