Some people in San Francisco reported feeling the temblor, which was measured at a depth of nearly 9 miles at the epicenter, the USGS said.
One San Rafael resident told NBC Bay Area she felt her house shake, but nothing was damaged. A San Francisco resident said his chandeliers were swaying and things fell off shelves in his home.
