The San Francisco Bay Area was rattled by a minor earthquake Friday morning that struck just off the coast, followed by at least two aftershocks.
The 3.6 magnitude quake struck at 7:02 a.m. off the coast of San Francisco, with its epicenter about five miles southwest of the Golden Gate Bridge and two miles west of the Great Highway, according to data from the U.S. Geological Survey.
The preliminary measurement from the USGS was a 3.7 magnitude quake before it was slightly downgraded later Friday morning. The quake had a depth of about five miles, the data indicated.
