MEDFORD, Okla. (AP) — The U.S. Geological Survey reports three earthquakes in Oklahoma, including one with a preliminary magnitude of 4.2.
Sheriff's officials say there are no reports of injury or of significant damage, although there were reports of people being jolted awake by the temblors.
The USGS says the 4.2 magnitude quake occurred at 4:24 a.m. Sunday about 16 miles southeast of Medford in north-central Oklahoma.
A 3.8 magnitude quake was recorded at 12:59 a.m. about four miles northwest of Prague and a 3.5 magnitude temblor occurred at 6:18 a.m. five miles northeast of Edmond.
Geologists say quakes of magnitude 2.5 to 3.0 are generally the smallest that are felt by humans and that damage is not likely in earthquakes with magnitudes below 4.0.
