Earthquakes are devastating for human activity and the way to mitigate future losses is to understand the earthquakes that hit a region in the past and the geological structures that generate them. The information gained from these structures and past earthquakes is essential especially in intraplate regions usually considered stable with low recurrence. We focus our current research in intraplate regions of the Iberian Peninsula, characterizing the seismicity and the active geological structures with multidisciplinary techniques such as seismotectonics, paleoseismicity, historical seismology and archaeoseismology. Our current research is focused on the North Iberian Peninsula and to carry out this study we are characterizing the anomalous seismicity through statistical analysis and finally identifying and characterizing the active faults of the region through neotectonic and paleoseismic techniques, we are also conducting historical studies of historical and archaeological earthquakes to complete and improve the seismic catalogue of the area.
