Widespread mass-wasting features on the submerged flanks of Stromboli Volcano (Italy)

Active insular volcanoes are dynamically evolving structures, commonly characterized by steep slopes and high-sedimentation rates due to volcanic activity. These conditions lead to the development of diffuse mass-wasting and erosive-depositional processes along the volcanic flanks. A review of main instability features identified along the submerged portions of Stromboli Volcano (Italy) is presented; they affect about 90% of the submarine extension of the edifice and show different scales and timing. Insights on tsunamigenic potential related to these processes will be also discussed.
