A magnitude 3.5 earthquake hit the town of Colma southwest of San Francisco Saturday morning.
Centered offcoast, 16 miles southwest of The City, the minor earthquake shook the bay at 8:41 a.m. and lasted less than a second, according to the U.S. Geological Survey.
More than 2,300 locals reported their homes shaking, but officials say the quake did not cause damage or injuries.
The incident prompted local emergency services and businesses to remind locals about earthquake protocols and guidelines on social media.
