A strong earthquake measuring 6.5 magnitude on the Richter scale hit the coast of Northern California Saturday afternoon, the U.S. Geological Survey reported.

The quake struck at about 4:27 p.m. local time and was centered about 33 miles (53 kilometers) from Eureka, a city along the Northern California coast, according to information posted on the USGS website.

There were no reports of fatalities so far but there were some injuries and damages as well as power outrages in several coastal communities, local media reported.

According to the USGS, the quake was felt as far south as Capitola, a central California coastal city, and as far north as Tiller in the U.S. state of Oregon.

No tsunami warnings were issued.

On Thursday and Friday, two light quakes of 4.1 and 3.8 magnitude had rattled the U.S. San Francisco Bay Area.
