Résumé
Marine deposits located between 0 and 5 m topographic elevation (above mean high tide level) outcropping along the Ría de Arosa-Ría de Pontevedra coast recorded paleosea-levels development during the Last and Present Interglacials periods (OIS 5, OIS 1). A normal fault system with N160°E orientation was the main control on topographic elevation of the Last Interglacial marine deposits and aeolian. Colluvial accumulation during the Last Glacial Period. Sedimentary structures observed in colluvial deposits suggest a paleoseismic origin.
