Officials say a powerful magnitude 6.9 earthquake struck Sunday night off the coast of Northern California, but there was no danger of a tsunami.
The U.S. Geological Survey says the temblor struck at 9:18 p.m. PDT about four miles beneath the Pacific seabed and about 50 miles west of Eureka.
Sheriff's and fire officials in Humboldt County, which includes most of the populated areas near the quake, say there have been no calls about damages or injuries.
USGS seismologist Susan Hoover says more than 300 people have reported feeling the temblor on their website.
The National Tsunami Warning Center says there is no tsunami danger for the region.
