The Ionian slopes of the Calabrian continental margin have been affected by mass movements of varying style, scale and age. Here we present examples of seabed and subsurface features identified from recently acquired multibeam morpho-bathymetric data and sub-bottom profiles, being interpreted in the framework of the MAGIC project. Four different types of mass wasting phenomena are recognized: mass transport complexes (MTCs) within intra-slope basins, isolated slide scars on slopes, possible features of gravity sliding above Messinian salt and headwall scarps in canyons. An improved understanding of past and present processes of mass failure on the Calabrian margin is strategic for assessments of the geohazards they may represent.

Abstract
The Ionian slopes of the Calabrian continental margin have been affected by mass movements of varying style, scale and age. Here we present examples of seabed and subsurface features identified from recently acquired multibeam morpho-bathymetric data and sub-bottom profiles, being interpreted in the framework of the MAGIC project. Four different types of mass wasting phenomena are recognized: mass transport complexes (MTCs) within intra-slope basins, isolated slide scars on slopes, possible features of gravity sliding above Messinian salt and headwall scarps in canyons. An improved understanding of past and present processes of mass failure on the Calabrian margin is strategic for assessments of the geohazards they may represent.
