An earthquake strikes Northern California's Plumas County with a preliminary magnitude of 5.7.
Rafael Abreau, a geophysicist with the U.S. Geological Survey's National Earthquake Center, says the temblor struck at 8:47 p.m. and was centered six miles west northwest of Greenville, and 26 miles southwest of Susanville.
Abreu says there have been no reports of damage in early field reports.
KCRA-TV in Sacramento reports that the quake was felt in downtown Sacramento, about 145 miles south of the epicenter.
There have been eight aftershocks ranging from 2.6-to-3.5-magnitude.
Abreu said the shaking measured by the quake could have inflicted light damage of structures.
