Earthquakes Rumble Through Oklahoma

The U.S. Geological Survey says a 4.7 magnitude earthquake struck northern Oklahoma early Monday. There are no immediate reports of damage, but the quake was felt throughout much of the state and into Kansas.

The USGS says the quake hit at 3:49 a.m. in extreme northern Oklahoma. The epicenter was 16 miles west-southwest of Medford, or about 80 miles south of Wichita, Kansas.

The earthquake was upgraded after initial reports that it was magnitude 4.5.

Other earthquakes have struck since that one. The first -- with a magnitude of 3.0 -- centered just outside the Oklahoma City metropolitan area at 5:50 a.m. Monday.

A 3.1 magnitude quake near Perry was recorded at 7 a.m. Then at noon, a 3.2 magnitude quake was reported in Alfalfa County.

The quakes come after a 4.7-magnitude temblor hit northern Oklahoma on Nov. 19. That earthquake prompted state regulators to shut down some oil and gas wastewater disposal wells in the area and reduce the volume at others.
