Mapping faults is a vital part of seismic risk assessment. In northern Baja California, the Mexicali Valley is a seismically active region in which the Cerro Prieto and Imperial transform faults draw the main tectonic boundary at this latitude. Here, focus will be made on the southern segment of the Imperial Fault by integrating processed seismic data, acquired gravity data, and complementary observations. Preliminary results show that the Imperial Fault continues its way through the city of Guadalupe Victoria and finally interacting with the Cerro Prieto fault near the town of Plan de Ayala. All in all, our research aims to enhance seismic risk assessment in the Mexicali Valley by providing inputs for regional community fault models.
