Description :
This paper presents : a) a GIS-based multivariate statistical approach for mapping landslide susceptibility, b) several dimensionless landslide susceptibility indexes developed to quantify and weight the influence of individual categories for given potential risk factors on landslides and c) a case study in southern California, which uses 11 111 seismic landslide scars collected from previous efforts and 5389 landslide scars newly digitized from local geologic maps. In the case study, 7 potential risk factors were selected to map landslide susceptibility.
