A magnitude 4.7 earthquake struck northern Oklahoma early on Thursday, with reports the temblor was felt in neighboring Kansas.

The U.S. Geological Survey said the 1:42 a.m. quake’s epicenter was centered 8 miles (13 km) southwest of Cherokee, Oklahoma. It had a depth of 3.8 miles (6.2 km).

The early morning quake was felt as far away as Wichita, Kansas, about 107 miles (172 km) to the north, according to media reports.

It was unclear if there was any damage or injuries. Kansas Emergency Management could not immediately be reached for comment.

Residents in both Oklahoma and Kansas took to Twitter to report feeling their homes shake.

“Definitely the largest #earthquake I’ve felt in Kansas. Lasted a while–heard things rattling,” one user said.

The area has seen a spike in seismic activity in recent years with Oklahoma geologists documenting strong links between increased seismic activity in the state and the injection into the ground of wastewater from oil and gas production.
