Another earthquake has struck north-central Oklahoma.
The U.S. Geological Survey reports that the 3.0-magnitude quake struck at 7 a.m. Monday.
It struck 5 miles east-southeast of Medford and 29 miles north-northeast of Enid. It had a depth of 1.8 miles.
The latest quake follows a handful of temblors Sunday. The largest was a 3.2-magnitude quake centered 2 miles southeast of Stillwater.
Geologists say earthquakes of magnitude 2.5 to 3.0 are the smallest that are felt by humans. Earthquakes below magnitude 4.0 generally do not cause damage.
