We present an updated version of the European landslide susceptibility map ELSUS 1000 that was released through the European Soil Data Centre in 2013. The ELSUS V2 map shows the landslide susceptibility zonation for individual climate-physiographic zones across Europe. ELSUS V2 covers a larger area of Europe than ELSUS 1000 as it includes Iceland, Cyprus, the Faroes, and the Shetlands, at a higher spatial resolution (200 x 200 m). The updated map was prepared using the same semi-quantitative method as for ELSUS 1000, combining landslide frequency ratios information with a spatial multi-criteria evaluation model of three thematic predictors_ slope angle, shallow subsurface lithology and land cover. However, the new map was prepared using also_ i) an extended landslide inventory, containing 30% of additional locations for model calibration, map validation and classification, and ii) a new lithological data set, based on harmonized shallow subsurface information derived from the International Hydrogeological Map of Europe (IHME). The new version of the map increases the overall predictive performance of ELSUS by 8%.
