Recent alluvial deposits adjacent to the Azuero-Sona fault zone, at Azuero peninsula, Panama, are inspected with resistivity measurements in order to find narrow vertical ruptures parallel to the main strike of the fault, which could indicate neotectonic activity. Five 2D resistivity sections at three locations, Malena, Sapotal and Quebro, were obtained with semiDemo version of RES2DINV software through six lines of data acquisition: two lines taken at the same location were merged into one. Profiles at Sapotal and Quebro show low resistivity elongated zones (1.40 ?m at Sapotal and 45.7 – 57.3 ?m at Quebro) which indicate percolation of fluids in vertical structures. These structures are interpreted in this study as a product of neotectonic activity of Azuero fault. Inferred ruptures reach depths of 3.13 m at Sapotal and 1 and 5 m at Quebro. At Quebro, a previous GPR survey shows the same vertical structure found with resistivity. Using orientations of both resistivity and GPR profiles, a rupture direction of ~98° is obtained, nearly parallel to the main strike of Azuero fault (120°). The orientation of this structure corresponds to a counterclockwise synthetic structure in the Riedel shear zone of the Azuero Sona fault zone. Also, a model of generation of the terraces is proposed: at Sapotal an erosional-depositional event of a tributary created two terraces while at Quebro one tectonic response and a climatic event, which changed the river course, created three terraces.
