Gravitational instabilities on the continental slope off the Campania Region: two case histories in the Naples and Salerno Bays (Southern Tyrrhenian sea)

The study of submarine gravity instabilities represents a research line of increasing interest, mainly for its implications in the monitoring of the deep and coastal environment in terms of definition of geological and environmental hazard. In the last years, the acquisition of large-scale morpho-bathymetric data on the submerged portions of the volcanic edifices and as, a general rule, in the oceanic basins and in the seas, has furnished interesting data, giving a new impulse on the knowledge of the structure and the geological evolution of the oceans. Geophysical and geological data have been collected to improve the knowledge of submarine instabilities offshore the Campania Region. This allowed for a discrimination between slow submarine instabilities (creeping, slumping, DGPV) and fast submarine instabilities (debris avalanches, rock-falls, roto-translational slidings).
