Stromboli is a 3000 m high island volcano, rising to 900 m above sea‐level. It is the most active volcano of the Aeolian Archipelago in the Tyrrhenian Sea (Italy). Major, large volume (1 km³) sector collapses, four occurring in the last 13 kyr, have played an important role in shaping the north‐western flank (Sciara del Fuoco) of the volcano, potentially generating a high‐risk tsunami hazard for the Aeolian Islands and the Italian coast. However, smaller volume, partial collapses of the Sciara del Fuoco have been shown to be more frequent tsunami‐generating events. One such event occurred on 30 December 2002, when a partial collapse of the north‐western flank of the island took place. The resulting landslide generated 10 m high tsunami waves that impacted the island. Multibeam bathymetry, side‐scan sonar imaging and visual observations reveal that the landslide deposited 25 to 30 × 10⁶ m³ of …
