Short summary
Short summary
The NW Iberian Peninsula provides one of the most complete Variscan sections in Europe, showing the transition between a sedimentary domain with folds and thrust and a metamorphic domain with igneous intrusions. By processing the seismic ambient noise recorded by several seismograph networks in this area, new 3-D S-wave velocity and radial anisotropy models were created. These models reveal the limit between the two domains, delineating the core of the large western European Variscan Belt.

Short summary
We are a multidisciplinary research group interested in the study of landscape dynamics and its interaction with human communities. At present, we are working in a project concerning with the evolution of the Cantabrian Coast cliffs. One of the studied areas is the Jurassic coast in which the Tazones Lighthouse slope is located. This represents an exceptional opportunity to analyse in real time the Jurassic cliffs retreat of the Cantabrian Coast, a question that remained not quantified.

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.
