Assessing Crustal Deformation within a Transect across the San Andreas Fault near Bombay Beach using GPS Data

Event Center A & B

A model of elastic motion along with Global Positioning System (GPS) was employed in order to establish the slip rate for the San Andreas Fault (SAF), the San Jacinto fault (SJF), along with several other faults on the boundary of the Pacific-North American plate near the southern end of the San Andreas Fault. After testing 120, 959 possible slip rate combinations, the slip rate for the San Andreas Fault was determined to be 10- 19 mm/yr, with an optimal slip rate of 15 mm/yr. The San Jacinto Fault-Clark strand was found to be 6-15 mm/yr with a best fit slip rate of 11 mm/yr. The slip rate of the San Jacinto fault-Coyote Creek strand was found to have between 6-11 mm/yr, with a best fit slip rate of 9 mm/ yr. Other faults that traverse through the Bombay Beach transect were found to have between 0 and 6 mm/yr., of slip.
