Abstract: In this work, the cliffs of a 36.9 km coast section in the surroundings of Peñas Cape (Gozón, Asturias, N Spain) are characterized.The objective is to understand the geomorphological processes that act in this area and to quantify the retreat of the cliffs. A 1:5000 geomorphological map has been developed based on field data and
photointerpretation of PNOA photographs (years 2006 and 2017), as well as Google Earth and Iberpix imagery. The information has been managed through a Geographic Information System that has allowed the development and analysis of digital terrain models of slope, orientation and curvature. The obtained results show that: 1)in the surroundings of Peñas Cape, gravity processes predominate, in particular, rockfall, topples, flows and landslides; 2) the steepest cliffs facing west are those suffering the greatest erosion, developing the largest instabilities and 3) the average retreat rate obtained for the period 2006-2017, at certain points of this section of coast is 0.57 m/year, reaching rates up to 1.22 and 2.19 m/year in the surroundings of Candás and Luanco, respectively.
