          Abstract

          En el noroccidente colombiano, dentro del contexto de la orogenia Andina, se han desarrollado importantes fallas activas, que afectan secuencias turbidíticas de la Formación Penderisco, en el eje de la Cordillera Occidental, las cuales presentan actividad y grado de amenaza sísmica alto/moderado para esta región. Este trabajo utiliza la tomografía de resistividad eléctrica con el fin de evaluar la capacidad del método en la delineación y configuración de estructuras menores asociadas a la Falla Abriaquí. A partir de la realización de líneas geoeléctricas transversales a la Falla Abriaquí y la obtención de imágenes tomográficas de resistividad eléctrica en dos localidades, mediante el método Dipolo-Dipolo, se infiere una alta correspondencia entre la distribución espacial de la resistividad eléctrica obtenida y las ideas propuestas a partir de indicadores morfotectónicos, y en particular entre la configuración inferida de la Falla Abriaquí a partir de la resistividad y los modelos 2D elaborados para cada locación con base en criterios geomorfológicos.

          Major active faults are affecting turbidite sequences of the Penderisco Formation in Northwestern Colombia, located along the axis of the Western Cordillera. Such faults are currently active and generate a high/moderate degree of seismic hazard in this region. In this work we use the electrical resistivity tomography method to evaluate its ability to delineate minor structures and to identify displaced blocks associated with the Abriaquí Fault. Electrical tests were carried out in a perpendicular direction to the Abriaqui Fault, obtaining tomographic images of electrical resistivity at two different locations using the Dipole-Dipole method. From the results we infer a high correspondence between the obtained spatial distribution of resistivity and the previous ideas of the underground configuration based on geomorphic and tectonic criteria. In particular, the inferred configuration of the Abriaquí Fault from electrical resistivity is highly consistent with the 2D models previously proposed.
