Abstract

We study crustal deformation across the Ballenas marine channel, Gulf of California, Mexico using InSAR and campaign GPS data. Interseismic velocities are calculated by time-series analysis spanning five years of data. Displacements from the August 3 2009 Mw 6.9 earthquake are calculated by differencing the most recent observations before and after the event. To estimate the offset across the marine channel we calibrate the InSAR velocity and displacement fields using the corresponding GPS data. Unfortunately, the InSAR interseismic velocity field is affected by residual tropospheric delay. We interpret the GPS interseismic and the GPS and InSAR coseismic deformation data using dislocation modeling and compare the fault kinematics during these periods of the earthquake cycle.
