Over time, most of the scientific community's studies of basaltic volcano activity have focused on the normal Strombolian activity and on shallow conduit processes. However, an important and missed window to more realistically understand the activity of the whole plumbing system in a basaltic volcano is represented by the paroxysmal activity. The paroxysm represents a particularly energetic and dangerous "unexpected" event, with a probable deep origin, that interrupts the normal eruptive activity. The recent events which occurred at Stromboli (summer 2019) and Etna (2021 and 2022) have once again focused attention on the importance of understanding the mechanisms of triggering and development of these particular eruptive phenomena. To this aim the development of a phenomenological model for the onset of paroxysm requires a multidisciplinary approach. In this session we expect contributions from volcanology, geophysics and petrology, combining theoretical, empirical and experimental methods aimed at understanding the origin and dynamics of paroxysmal eruption.
