||The Cerro Prieto geothermal field, located in the Mexicali Valley, B.C., Mexico, has been exploited for energy production since 1973. Geodetic and geotechnical measurements have revealed subsidence likely due to a combination of fluid extraction and tectonic movement in this active tectonic area. This paper reports preliminary results of an ongoing project in which satellite radar (ERS 1/2 and ENVISAT Cband) data is used to map the deformation in this region via interferometric processing. The project objective is to use Differential Interferometric Synthetic Aperture Radar (DIn- SAR) together with geodetic (leveling surveys) and geotechnical (tiltmeters and extensometers) techniques to monitor the spatio-temporal evolution of the surface deformation in the study area and to distinguish among several possible causes (tectonics and fluid extraction) and mechanisms (aseismic and seismic slip).
