A joint regional slope mass movement susceptibility map

Abstract

The paper introduces an approach to create a jointed slope mass movement susceptibility map at a regional scale using a combination of three different susceptibility maps. For this purpose, two approaches were chosen, maximum value and unique value. Slightly different approaches were used to produce the three models that represent landslide, debris-flows, and rockfall susceptibility maps of Slovenia at scale 1:250,000. Nevertheless, the joint susceptibility indicates that 32.5% of Slovenian territory is highly susceptible to slope mass movements, while in the same area approximately 23% of population lives.
