A Submarine Landslides Database of Calabrian Continental Margins (Central Mediterranean Sea).

Submarine landslides are complex and widespread natural events occurring all over the world, in every latitude and depth. Understanding the genesis and evolution of submarine landslides requires interpreting the nature of the seafloor, on which these landslides occur. This work presents a large database on the submarine landslides distribution along the Ionian and Tyrrhenian continental margins of Calabria (southern Italy), based high-resolution bathymetric data. An area of over 12,000 km2 in the central Mediterranean Sea, characterized by active tectonics, was analyzed using specific standards. A total of 1,945 submarine landslides has been mapped, and several morphometric parameters describing the size, shape and geometry have been measured and analyzed. Such datasets may allow us to investigate the relationship between landslides morphology, spatial distribution, and the possible controlling factors of submarine landslides.
