Significant Earthquakes Centered in
Los Angeles County

NOTE:  In the event of an earthquake, the safest place to be is not in a doorway, but under a table.

Due to the two inch slippage of the San Andreas fault every year, Los Angeles City Hall is now about 10 feet closer to San Francisco than when it was built in 1924. Scientists project that it should be located in the suburbs of San Francisco in approximately 15 million years.

The July 29, 2008, Chino Hills earthquake, measured at a magnitude 5.4, was centered in Riverside County.
It was, however, widely felt throughout Southern California, including Los Angeles County.

About 30 earthquakes occur every day in Southern California. Most have a magnitude of less than 2.0.

No evidence exists that earthquakes are more likely to occur in certain kinds of weather.

The best place to see any part of the monstrous, 800-mile San Andreas Fault is in Palmdale in a road cut along the
Antelope Valley Freeway (Route 14) just north of Avenue S. The last time this part of the fault was active was in 1857.

An excellent publication on earthquakes and earthquake safety in Southern California is Putting Down Roots in
Earthquake County
by the Southern California Earthquake Center. You may read the publication online or contact
the Center
(phone 213-740-5843, fax 213-740-0011, or e-mail scec@usc.edu) to request an order form by mail or fax.
