Resumo

The Ventaniella fault is significant structure in NW Iberia for the seismicity in some of the fault segments. It runs for at least 450 km from a continental platform located in offshore to the Duero Basin across the Cantabrian Mountains. The fault zone is covered by superficial deposits of varied origin that hinder the observation of fault structure at the surface. In this context, the electrical resistivity tomography method is useful to establish the ground structure to a depth of tens of meters. The results of applying this method depend partly on the geometric arrangement of sensors. In this contribution we present the results of the study of the fault zone in the Avilés fault segment in which three array configurations were used: dipole-dipole, Schlumberger and Wenner. The data obtained allow us to constrain to what extent the various configurations tried are useful in determining internal structure, position and range of depths of the main fault and associated structures.
