The U.S. Geological Service is reporting that a magnitude-6.4 earthquake struck in remote western Nevada early Friday.

The temblor was reported at 4:03 a.m. about 35 miles outside Tonopah, just east of the Sierra Nevada range.

The initial quake struck about 4.7 miles (7.6 kilometers) deep and at least six sizable aftershocks were recorded shortly thereafter, including two with estimated magnitudes of 5.4.

People from Salt Lake City, Utah, to California's Central Valley reportedly felt the quake.
