CARMEN, Okla. — Oklahoma Corporation Commission is working to formulate a response to recent, strong earthquakes near Cherokee and Crescent.

"We are working the earthquakes that hit in the Cherokee area this morning," OCC spokesman Matt Skinner said Thursday, Nov. 19, 2015. "There will be a response, but there's more data we need."

He later said the OCC also is working on its response to the quakes near Crescent, centered at Marshall, and may take some time to formulate the response on both cases.

The largest earthquake of four earthquakes to hit in Alfalfa County Thursday, a 4.7 magnitude, struck at 1:42 a.m., according to the U.S. Geological Survey. It was centered at Carmen, eight miles southwest of Cherokee and 36 miles west-northwest of Enid. The quake was four miles deep.

Northwest Oklahoma residents reported being frightened by the strong shaking of the temblor.

Martha Robertson, who was awake at 1:42 a.m. in her home in Waukomis, Okla., said the earthquake lasted several minutes.

A Fairview area resident posted a picture of a crack in the drywall of her living room on Facebook.

There were no immediate reports of damage or injuries from the quake, which was felt across Oklahoma and more than 300 miles away in the Kansas City area.
