USGS: Magnitude 6.0 Quake off Northern Calif Coast

PETROLIA, Calif. The U.S. Geological Survey reports the temblor hit at 12:20 p.m. PST about 35 miles northwest of the town of Petrolia and nearly 50 miles west of Eureka.

An employee at the Humboldt County Sheriff's Office says there are no immediate reports of major injuries or damage.

Humboldt County spokesman Phil Smith-Hanes says he felt a rolling sensation, but the movement didn't feel as severe as the magnitude-6.5 quake that struck the same area Jan. 9.
