MEDFORD, Okla. (AP) — The U.S. Geological Survey has recorded a magnitude 3.4 earthquake in north-central Oklahoma.
The quake was recorded at 8:34 a.m. Sunday seven miles southeast of Medford, about 85 miles north of Oklahoma City.
No injuries or damage have been reported, but the USGS reports the earthquake was felt as far away as Claremore, 115 miles to the east and from central Oklahoma to near Hutchinson in south-central Kansas. Geologists say damage is unlikely in earthquakes below magnitude 4.0.
Oklahoma's earthquakes have been linked to oil and gas production, and state regulators have shut down or imposed new restrictions on underground wells that are used for wastewater disposal.
