ABSTRACT
This chapter discusses the landslide susceptibility assessment of the submerged slopes of the volcanic Albano Lake. A high resolution bathymetry obtained through a multi-beam sonar survey is available, while no data about the submerged geological setting exist. Landslide susceptibility analysis of the subaerial slopes has been used as a point of reference. Researches dealing with landslide hazard analysis of coastal areas have to face a peculiar problem since environments are composed by both subaerial and subaqueous slopes. On the basis of the good results obtained for the subaerial slopes taking into account only the DEM derived factors, in a second phase of the research the authors attempted to extend the results obtained from the subaerial spatial analysis to the submerged slopes in order to evaluate the corresponding landslide susceptibility. Thus the calculated weights of each class of DEM derived factors were used to generate a prediction image for the submerged slopes.
