ABSTRACT
What do we know about landslide risks? A first theoretical definition was given by Varnes in 1984: “Risk is the probability of an event of a given magnitude multiplied by its consequences”.
Since then, many technical and scientific papers have been written on this topic (i.e. Brabb, 1984; Brand, 1988; Bunce et al., 1997; Carrara, 1992; Carrara et al., 1992; Cherubini et al., 1993; Cruden & Fell, 1997; Cruden & Varnes, 1994; Einstein, 1988; Fell, 1994; Fell et al., 2000; Finlay & Fell, 1997; Hungr, 1981; Hungr et al., 1993; Hutchinson, 1992; Leroi, 1997; Mulder, 1991).
