Magnitude 4.0 Earthquake Rattles Bay Area Early Tuesday Morning

FREMONT, Calif. (AP) -- Authorities say a magnitude 4.0 earthquake has rattled the San Francisco Bay Area, but no injuries or property damage is reported.

The U.S. Geological Survey says the quake hit shortly after 2:30 a.m. Tuesday near Fremont, about 35 miles southeast of San Francisco. The initial magnitude was reported as 4.1 before being revised down. It struck at a depth of about 5 miles.

A series of much smaller aftershocks occurred, ranging in magnitude from 1.0 to 2.7.

Fremont police say there have been no reports of damage or injuries.

The quakes come nearly a year after a magnitude 6.0 earthquake struck the region. The August 2014 quake was the largest to hit Northern California in a quarter-century. That quake killed one woman and caused about $400 million in property damage in Napa Valley.
