Faults in the upper left are part of the Eastern California Shear Zone, connecting northward with the Walker Lane region. Faults extend deeper than shown. Cumulative energy released by all earthquakes in Southern California from 1932 through July ...
It is estimated that this zone is capable of producing a quake of 6.5–7.5 M W. The projected interval between major rupture events is 250 years. The last major rupture event on the main Elsinore fault was in 1910 with a 6 M W earthquake centered just northwest of the city of Lake Elsinore. [3]

The earliest known earthquake in the U.S. state of California was documented in 1769 by the Spanish explorers and Catholic missionaries of the Portolá expedition as they traveled northward from San Diego along the Santa Ana River near the present site of Los Angeles. Ship captains and other explorers also ...
The Whittier Fault is a 40-kilometer (25 mi) right-lateral strike-slip fault that runs along the Chino Hills range between the cities of Chino Hills and Whittier.The fault has a slip rate of 2.5 to 3.0 millimeters (0.098 to 0.118 in) per year.
Officials have estimated that the typical retrofit of a soft-story building in L.A. costs from $80,000 to $160,000, although costs can vary depending on the size of the building.
