A small earthquake has shaken Northern California's wine country.
The U.S. Geological Survey says in a computer-generated report that a magnitude-3.4 earthquake struck at 2:01 a.m. Monday. It was centered seven miles north-northeast of St. Helena in Napa County.
St. Helena police dispatcher Socorro DeLuna says there are no reports of damage.
Hours earlier and about 70 miles away, a magnitude-3.5 quake struck north-northeast of the San Francisco Bay area community of San Leandro.
That quake hit at 8:08 p.m. An Alameda County Sheriff's dispatcher says there were a few callers asking if there was a quake, but no one reported damage.
