Earthquake Northern California 2015 - The U.S. Geological Survey (USGS) has announced that a magnitude 5.7 earthquake struck just offshore northern California on Wednesday.

The northern California 2015 earthquake was initially reported to be weaker with a magnitude 5.1. However, officials with the USGS quickly changed the figure to a 5.7.

The tremor struck around 1:08 p.m. and was centered 40 miles (65 km) southwest of Eureka, and 25 miles southwest of Ferndale.

Reports indicate that the earthquake did not cause any injuries to persons or damages to properties.

The tremor was felt as light and moderate shaking in Eureka, Fortina and also as far inland as Red Bluff.

Experts say a magnitude 5.7 earthquake is quite common and although they are considered moderate, they have the ability to cause significant damage.

"It wasn't the biggest one I've ever felt, but I felt it," Eureka police spokeswoman Brittany Powell said about the earthquake which struck at a depth of 17 kilometers, about 10.6 miles

Powell said she felt 'a little roll and shake,' which lasted for seconds. As of Wednesday afternoon, police say there had been no reports of any casualties.

The National Tsunami Warning Center has announced they do not expect that a tsunami would be generated by the earthquake in northern California.

"It was a sizable earthquake, but not large enough to cause concern," said David Walsh, an oceanographer in Hawaii with the Pacific Tsunami Warning Center.

USGS officials say the earthquake in northern California 2015 caused at least two aftershocks. One of them is reported to have been a magnitude 3.3- and occurred about 300 miles in the San Jose.
