A small earthquake has shaken the San Francisco Bay area.
The U.S. Geological Service says a magnitude 3.6 earthquake struck at about 11:36 p.m. PDT on Tuesday. The quake was centered about six miles southeast of Oakland and was also felt by people across the bay in San Francisco.
USGS geophysicist Carrie Ann Bedwell says the magnitude of the temblor carries little risk of damage.
The quake comes at the end of a day in which a magnitude 5.8 earthquake jolted much of the eastern United States, the strongest to hit that region in decades.
