MEDFORD, Okla. (AP) — The U.S. Geological Survey says an earthquake centered near the northwest Oklahoma town of Medford had a preliminary magnitude of 4.5. The quake was reported at about 11:10 a.m., seven kilometers northwest of Medford. A Grant County dispatcher said there were no immediate reports of damage.  People across Oklahoma, as well as in Kansas and Arkansas, reported feeling the quake. The USGS says the quake occurred at a depth of about 7.8 kilometers.
