MEDFORD, Okla. (AP) – The U.S. Geological Survey has recorded four small earthquakes, including a magnitude 3.3 quake near Medford in northern Oklahoma.
The USGS reports that Monday’s quake occurred about 10:15 a.m. and was recorded about nine miles west-northwest of Medford at a depth of about three miles.
The agency says a 3.1 magnitude quake was recorded at about 11:50 a.m. about 10 miles east of Cherokee, also about three miles deep.
The USGS says two magnitude 2.8 quakes were recorded near Perry in north-central Oklahoma. The first was recorded at 11:22 p.m. Sunday and the second was at 2:30 a.m. Monday.
Geologists say earthquakes of magnitude 2.5 to 3.0 are generally the smallest that are felt by humans and damage is not likely in quakes below magnitude 4.0.
