SAN FRANCISCO—A 3.3-magnitude earthquake that originated just off the coast of San Francisco jolted part of the Bay Area on Sunday, August 9.
According to data provided by the US Geological Survey, the quake hit at 1:26 p.m. local time and was centered about 9 miles west of San Francisco, at a depth of approximately 7 miles.
The epicenter was along the San Andreas Fault Line and exceptionally close to the epicenter of the deadly 1906 San Francisco Earthquake that leveled much of the city and took the lives of around 3,000 people. The strength of that quake measured 7.8 on the Richter scale.
There are no known reports of any serious injuries or damage from the earthquake. No significant aftershocks have been felt or reported.
The Pacific Tsunami Warning Center indicated that no tsunami warning was put into effect.
Most of the earthquake reaction is said to have emerged from the Outer Sunset District. Twitter user and neighborhood resident Alejandro De La Cruz tweeted: “Living on a hill in the Outer Sunset, I sure felt the hell out of that earthquake.”
It is not clear exactly how long the tremor of the initial quake lasted, but another user tweeted: “In San Francisco, and the entire house just shook for 10 seconds.”
At least one account of feeling the earthquake has been reported as far away as Richmond, CA, more than 30 miles northwest of the epicenter.
This earthquake comes almost one year to the date that the 6.0-magnitude South Napa earthquake struck and caused considerable damage to the Napa area. One woman was killed and about 200 others were injured.
It also comes three weeks after a 4.1 magnitude earthquake that originated from the Hayward Fault Line near Fremont, CA that shook up a greater radius throughout the Bay Area.
