Short summary
The seismic activity of the last 20 years within the West Iberian Margin away from the plate boundaries has been analyzed through the Spanish and Portuguese seismic network public databases. Previously defined as diffuse, the study reveals two distinct clusters in the NW–SE direction. Based on the characteristics of the events, some hypotheses for this activity are put forward and discussed, indicating the need for ocean-bottom seismometer data and high-resolution fault mapping.
