Magnitude 4.0 quake hits San Francisco Bay Area

PanARMENIAN.Net - Authorities say a magnitude 4.0 earthquake has rattled the San Francisco Bay Area, but no injuries or property damage is reported, according to the Associated Press.

The U.S. Geological Survey says the quake hit shortly after 2:30 am Tuesday, July 21, 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.
