Tensor actual de esfuerzos y fallas potencialmente activas en el Domo del Tormes (NO de Iberia)

Abstract

Located in the NW of the Iberian Peninsula, the Domo del Tormes is an intra-plate granitic domain made up of a Hercynian megastructure and traditionally considered of very low or null seismicity. The geology of the area makes difficult to determine the recent deformations and the characterization of neotectonic activity. The data compilation and further discussion of seismic activity in the area provide information on present day stress tensor orientation and the match of gravimetry, geological and structural data revealed a series of main anomalies related to faulting on a regional scale, defining some potentially active structures in the area.
