4.0 Shakes Central Oklahoma
LANGSTON, Okla. (AP) - The U.S. Geological Survey says an earthquake with a magnitude of 4.0 struck central Oklahoma early Thursday. There are no reports of damage or injuries from the temblor.
The USGS says the quake hit at 5:39 a.m. with an epicenter 4 miles southwest of Langston, or about 31 miles north-northeast of Oklahoma City. The earthquake had a depth of 3.1 miles, and the USGS says it could be felt in the Oklahoma City metropolitan area.
Oklahoma's earthquakes have been linked to the injection of wastewater underground by the oil and gas industry. State regulators have issued new directives on the practice.
Last year, Oklahoma recorded more than 900 earthquakes with a magnitude of 3.0 or greater.
