An earthquake with a preliminary magnitude of 3.7 occurred at 2:21 a.m. Wednesday in a rural area along the Utah-Idaho border.
The temblor's epicenter was located six miles northeast of Snowville, Box Elder County, and 22 miles southwest of Malad City, Idaho.
University of Utah seismologists reported that the shock was near the location of a magnitude 6.0 earthquake that occurred in March 1975.
Small-to-moderate-size earthquakes have been recorded in this area frequently in recent decades.
There are many small faults in the area, and seismologists have not traced the quake's source to a specific fault.
There were no reports of the earthquake being felt or doing damage.
