The Sciara del Fuoco (SdF) collapse scar at Stromboli is an active volcanic area affected by
rapid morphological changes due to explosive/effusive eruptions and mass-wasting processes. The
aim of this paper is to demonstrate the importance of an integrated analysis of multi-temporal remote
sensing (photogrammetry, COSMO-SkyMed Synthetic Aperture Radar amplitude image) and marine
geophysical data (multibeam and side scan sonar data) to characterize the main morphological,
textural, and volumetric changes that occurred along the SdF slope in the 2020–2021 period. The
analysis showed the marked erosive potential of the 19 May 2021 pyroclastic density current generated
by a crater rim collapse, which mobilized a minimum volume of 44,000 m^3 in the upper Sciara del
Fuoco slope and eroded 350,000–400,000 m^3 of material just considering the shallow-water setting.
The analysis allowed us also to constrain the main factors controlling the emplacement of different
lava flows and overflows during the monitored period. Despite the morphological continuity
between the subaerial and submarine slope, textural variations in the SdF primarily depend on
different processes and characteristics of the subaerial slope, the coastal area, the nearshore, and
“deeper” marine areas.
