ABSTRACT
In Spain, landslides are phenomena mostly concentrated in the mountainous areas and coastal cliffs. Landslides in Spain occur mostly in three main geomorphological contexts: the Alpine ranges associated to the steep relief, the coastal cliffs subjected to the sea erosion, and the Cenozoic basins filled with hard soils and weak rocks which are susceptible to landsliding, particularly in locations affected by fluvial erosion. The whole Cantabrian coast is dotted with landslides caused by the erosion and undermining of the cliffs. The most frequent types of failures in the alpine ranges are shallow landslides and debris flows, generated in surficial formations, particularly till deposits and colluvium. The Geological Survey of Spain is currently preparing a National Landslide Catalogue, according to the INSPIRE criteria. This catalogue may become a useful tool for evaluations and to establish a reliable relationship between climate change and landslide occurrence.
