TULSA, Okla. (Reuters) - A magnitude 4.7 earthquake struck northern Oklahoma early on Thursday, with the temblor felt in a radius of 100 miles (161 km) which included the city of Tulsa and the neighboring state of Kansas.
The U.S. Geological Survey said the 1:42 a.m. CST quake's epicenter was centered 8 miles (13 km) southwest of Cherokee, Oklahoma. It had a depth of 3.8 miles (6.2 km).
There have been no reports of any major damage or injuries.
A local emergency management official in Oklahoma said there was no immediate damage to bridges in a 25 miles (40 km) radius of the quake's epicenter.
Kansas Emergency Management could not immediately be reached for comment.
The quake comes about a month after an earthquake with a magnitude of 4.5 struck near the U.S. crude oil hub of Cushing, Oklahoma. That quake occurred just days after regulators imposed new rules for hydraulic fractural disposal operations meant to prevent temblors in the area and said more changes were possible.
The Oklahoma Corporation Commission (OCC), which regulates the state's oil and gas industry, ordered companies on Sept. 18 to shut or reduce usage of five saltwater disposal wells around the north-central Oklahoma city of Cushing.
It has taken additional measures since then.
Saltwater, a normal byproduct of oil and gas extraction work, is put into deep disposal wells that scientists say have contributed to a rash of small and medium-sized earthquakes in Oklahoma since 2009.
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.
