Submarine Mass Movements and Their Consequences

Abstract

The geomorphological interpretation of the high resolution bathymetry of the Albano lake (central Italy), together with conventional\r geological and geomorphological investigations for the subaerial slope, allowed us to identify several subaerial and submerged\r morphologies due to slope failures of different size and presumably age. Two main landslide categories will be decribed in\r this paper: totally submerged, combined subaerial-submerged landslides. Furthermore a detailed description of two past large\r slope failures (volume of 106m3) and the 1997 subaerial and submerged debris flow are presented. The wave induced by the 1997\r debris flow testifies also the tsunamigenic potential of these phenomena which is still more serious if the presence of coastal\r settlements is taken into account.
