Abstract
GPS data monitoring motions of benchmarks at the surface of the Earth, combined with a geophysical model of elastic motion in the upper section of the crust in response to buried dislocations on faults, were used to determine the slip rate at depth of the San Andreas, San Jacinto and other faults within a transect across the Pacific-North America plate boundary passing through the San Bernardino Mountains. The slip rate for the San Andreas fault was determined to be 6-16 mm/yr, with a best-fitting rate of 6 mm/yr. The slip rate of the San Jacinto fault was found to be 4-14 mm/yr, with a best-fitting rate of 14 mm/yr. The Eastern California Shear Zone slip rate range was determined to be 14-17 mm/yr, with a best- fitting rate of 15 mm/yr.
