 Abstract: Deformation in the Cerro Prieto pull apart basin (CP) located between Cerro Prieto and Imperial faults on the Mexican part of San Andreas System was studied for years. Leveling was realized in the basin by different agencies since 60’s, DInSAR analisis and GPS observations were realized many times since 1997. Since the subsidence caused by geothermal water extraction in the Cerro Prieto Geothermal Field affected the faults in the basin subsequently geotechnical instruments were installed for continuous monitoring. The creep and episodic slip were observed on the basin faults before the 2010 earthquake. When the M7.2 EMC strikes all the geotechnical instruments, installed on the CP faults, recorded displacements triggered by the earthquake. However, the post-seismic behavior of the records varies, and 3 typical behaviors can be distinguished: 1) the creeping has similar magnitude before and after the earthquake, 2) the deformation rate after the earthquake increases and 3) the cessation of creep on the fault for up to 6 years after which the creep reactivated with a magnitude similar to that before the earthquake. Applying an empirical relationship between magnitude and stress, the accelerometer data and Coulomb 3 modeling, we found that the dynamic stress is responsible for the triggering. For post-seismic behavior, the Coulomb static stress changes caused by the EMC earthquake, by tectonic stresses and by fluid extraction in the Cerro Prieto geothermal field are analyzed. It can be concluded that the EMC shadow is causing creeping cessation on the faults closest to the epicenter.
