ABSTRACT
The NW flank of the Stromboli Island is a large sector collapse scar (more than 200 m deep), filled by the products of the continuous explosive activity of the volcano, which are incessantly re-mobilized by slides over the whole subaerial and submarine slope. This process forms a sequence of volcaniclastic layers with interspersed blocks and thin lava flows. Volcaniclastic layers are predominant and have large continuity over the submerged and subaerial slope thus controlling the mechanical behaviour of the whole deposit.
