A 4.1 earthquake hit at 7:01 a.m. Wednesday morning 8.4 miles northeast of Hanna. The area is 25 miles north and west of Duchesne and 55 miles north and east of Provo.
A second, smaller earthquake measuring 3.0 struck the same area at 7:24 a.m.
Earthquakes are rare in the Uintah Mountains east of the Intermountain seismic belt, according to the U.S. Geological Service, and earthquakes recorded in the area are generally small.
“However, the stable, underformed bedrock at and near the ground surface over much of the area and neighboring Colorado Plateau to the south causes ground shaking to be felt over a much larger area than for a similar magnitude earthquake in western Utah,” the U.S.G.S earthquake event page states.
