Using GPS to Estimate Slip Rates of the San Andreas Fault, and other Faults within a Transect Across the Transform Boundary of the Pacific and North American Tectonic Plates through Desert Hot Springs

RM 211

I used elastic modeling of GPS data from a transect across the Pacific/North American plate boundary near Desert Hot Springs to estimate the slip rates of a section of the San Andreas Fault, as well as other major neighboring faults. This transect extends in a northeastern direction from the Pacific Ocean, about 91 km west of San Diego, California, to about 109 km southeast of Las Vegas, Nevada. The faults I tested within this transect, along with the obtained slip rates, are the Newport-Inglewood fault: 0-3 mm/yr, Elsinore fault: 3-7 mm/yr, San Jacinto fault: 11-19 mm/yr, the Banning and Mission Creek branches of the San Andreas: 5-20 mm/yr and 2-20 mm/yr respectively, Copper Mountain fault: 0-2 mm/yr, Mesquite Lake fault: 0-2 mm/yr, and Cleghorne Lake fault: 0-1 mm/yr.
