A magnitude-5 earthquake has rattled The Geysers region of Northern California, a rural area about 70 miles north of the San Francisco Bay Area.
A dispatcher with the Mendocino County Sheriff's Department says the Ukiah office shook lightly just after 8:40 a.m. Wednesday but there were no calls reporting damage or injury.
The U.S. Geological Survey says the quake's epicenter was 4 miles west of The Geysers and about 15 miles north of Healdsburg.
The USGS says the region is tectonically active.
The Geysers is a large geothermal field where steam is withdrawn to generate electricity. Small earthquakes are not uncommon there.
