EUREKA, California (AP) — Officials say a powerful magnitude-6.9 earthquake struck Sunday night off the coast of northern California, but there were no early signs of a tsunami.

The U.S. Geological Survey says the temblor struck at 5:18 GMT about four miles (6 kilometers) beneath the Pacific seabed and about 50 miles (80 kilometers) west of Eureka.

USGS seismologist Susan Hoover says more than 300 people have reported feeling the temblor on their website.

Pacific Tsunami Warning Center has issued a statement on the quake, but not a watch or an advisory.
