Stromboli is renowned for its persistent and mild "Strombolian" explosive activity, described by Mercalli in 1883 as "slightly explosive eruptions occurring at discrete but relatively regular intervals of seconds or minutes." This eruptive style shows however large variations in intensity (including 'major' and 'paroxysmal' explosions) and frequency, and is occasionally accompanied or replaced by lava emission from the crater area or vents located on the unstable western flank, known as Sciara del Fuoco. This activity is associated with rockfalls, debris slides, summit crater failures, and less frequently, tsunamigenic rock/debris slides or flank failures. Pyroclastic density currents (PDCs), are often linked to crater-rim failures or column collapses during paroxysmal explosions. Sporadic occurrences of PDCs from landslides of incandescent volcaniclastic deposits during paroxysms have reached inhabited areas, causing casualties.
This session solicits comprehensive contributions addressing the origins and the consequences of this intrinsic variability of the Strombolian regime. Particularly, we welcome contributions that address the entire Stromboli volcanic system, spanning from magma generation and ascent to tephra dispersal and remobilization, encompassing both causal factors and their impacts on the surrounding area. Submissions across various research fields are encouraged, including real-time observations, geophysical and geochemical monitoring data, geomorphological studies, analyses of eruptive products, especially with multidisciplinary approaches.
