Bay Area residents felt a jolt on Saturday morning after a magnitude 3.5 earthquake struck off the coast about 10 miles south of San Francisco.
The quake, which was centered near Colma and about 4.7 miles deep, hit at 8:41 a.m. on Oct. 5 and was followed by three microquakes—two within the first ten minutes after the first quake and one at 9:57 a.m., according to the United States Geological Survey.
