A small earthquake shook the southern Uinta Mountains early Wednesday, according to the University of Utah Seismograph Station.
The 4.1-magnitude earthquake hit just after 7 a.m., station monitors shows.
The earthquake's epicenter was about 8 miles north and east of Hanna and 26 miles north and west of Duchesne.
Duchesne County sheriff's office dispatchers said no damage or injuries had been reported.
Historical data shows that since 1962, seven earthquakes of magnitude 3.0 or greater have occurred within 16 miles of the Wednesday earthquake epicenter. The largest of those was a 4.5-magnitidue quake on Sept. 30, 1977.
