MEDFORD, Oklahoma — The U.S. Geological Survey has recorded several earthquakes near Medford in northwestern Oklahoma.
The USGS recorded at least seven quakes of magnitude 3.0 or larger near the Grant County town on Saturday and Sunday. The Grant County Sheriff's Office says there are no reports of injury or damage.
The largest quake was a magnitude 3.8 temblor recorded at 1:18 a.m. Sunday about five miles northwest of Medford — about 95 miles north of Oklahoma City. At least six other quakes ranging from magnitude 3.0 to 3.5 were recorded during the weekend — in addition to at least three others of magnitude 2.0 to 2.7.
Geologists say earthquakes of magnitude 2.5 to 3.0 are generally the smallest that are felt by humans and damage is not likely at magnitudes below 4.0.
