A magnitude-5.7 earthquake just off the Humboldt County coast rattled parts of far Northern California early Wednesday afternoon.
The U.S. Geological Survey reports the quake shook at 1:08 p.m. PST Wednesday about 40 miles southwest of Eureka. That shake was followed by at least three aftershocks.
Lt. Wayne Hanson of the Humboldt County Sheriff's Office told the Associated Press that no damage or injuries had been immediately reported.
People reported feeling it as far away as Chico, nearly 200 miles to the east. Many took to Twitter to report the shaking.
Wednesday's earthquake was centered near the Mendocino Triple Junction, where the Gorda, Pacific and North American tectonic plates meet just north of the point where the San Andreas Fault ends.
