OKLAHOMA CITY (KFOR) – If you felt the ground move on Monday morning, you’re not alone.

Shortly after 11 a.m. on Monday, KFOR began receiving reports across the state of a possible earthquake.

The US Geological Survey recorded a 4.6 magnitude earthquake with the epicenter just four miles northwest of Medford, Oklahoma. The magnitude was later updated to 4.5.

So far, there is no word on if the quake caused any damage.

The Oklahoma Corporation Commission announced that its Induced Seismicity Department and the Oklahoma Geological Survey are investigating the earthquake.

Often the size of an earthquake can change during the first investigations.

The USGS also recorded a 2.5 magnitude earthquake in the same area about an hour after the original quake.

The Oklahoma Corporation Commission is directing 3 Arbuckle oil and gas wasterwater disposal wells within 6 miles of the quake’s epicenter to shut-in.

Other Arbuckle disposal wells within 10 miles of the epicenter will be restricted to an average volume of 500 barrels a day.

The Arbuckle formation is the state’s deepest formation.
