To the south, the San Andreas blends into a series of faults, like the San Jacinto Fault, and it ...The San Andreas Fault stretches for 750 miles along much of the length of California, traveling belowground from the Bay Area south to the Salton Sea. It marks the tectonic boundary of the Pacific and North American plates as they slide horizontally past one another, 20 to 35 millimeters (0.8 to 1.4 inches) per year.Just days after a cluster of more than 200 small earthquakes shook the Salton Sea area of Southern California, scientists have found evidence of a second fault line that runs parallel to the massive San Andreas Fault - one of the state's most dangerous fault lines. The new fault appears to run right through the 56-km-long Salton Sea in the ...

The crust/mantle discontinuity (Moho) is visible as a continuous feature at a depth around 30 km but is offset 6 to 8 km beneath the SAF.Creep commenced sometime after 1929 and averaged 8 mm/yr. Between 1961 and 1967, the slip rate was about 15 mm/yr. Since 1979, two sites have been monitored in Hollister, one showing 6.6 mm/yr and the other, only 2.3 km northwest, creeps 12 mm/yr - the fastest rate of movement measured across any fault in the San Francisco Bay Region.''
