Abstract
Repeat multibeam surveys are used to investigate recent submarine landslides in three different areas on southern Italy, i.e. Stromboli, Southern Messina Strait and Puma Alice. High-resolution Digital Terrain Models (DTMs) depict the morphology of mass-wasting events, while residual maps of the difference between successive bathymetric surveys indicate failure volumes ranging from tens of thousands to millions of cubic meters. A tentative estimate of recurrence time for the slope failures was based on chronological constraints and historical reports, and gave values ranging from tens to hundreds of years. Characterizing mass-wasting events and their recurrence time is a necessary step for geo-hazard assessment of densely populated coastal areas.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
