5-5-5-5-5-5-5-5-5-5-5-5-5-5 From: Alessandro Bonforte <alessandro.bonforte@xxxxxxx> Dear colleagues, The deadline for submitting the abstract at the next IAVCEI Scientific Assembly (Rotorua, New Zealand, Jan 30 to Feb 3, 2023) is *September 3, 2022*, so we kindly invite you to consider the following session for your abstracts during these very few days remaining. Symposium: Using field data, geophysics, geochemistry, statistics, and modelling to probe volcanic and plutonic systems *Session: Analysis, Monitoring, Modelling of mass-wasting in volcanic areas* Mass-wasting in volcanic environment comprises a wide spectrum of phenomena, from lateral collapse to shallow debris remobilization, representing a major threat for societies. Slope instability can affect volcano edifices and their surroundings on different time scales; slow onset phenomena characterize long-term continuous movements, whereas fast onset events comprise sudden and catastrophic events. Interpretation is challenged by complex interactions between tectonic, magmatic, fluid, and gravitational processes. Moving masses behave in different ways, depending on water content and flow rheology, from flank spreading or collapse to granular or viscous flow. Many volcanoes are located in high-precipitation environments or are covered by snow or glaciers, which exacerbates the potential for landslides, lahars and debris avalanches. Melting of snow and ice can generate flood of water that can be converted to a lahar through the incorporation of granular material. The encounter with a river or an excessive rain can progressively dilute the flow to a hyper-concentrated streamflow. At volcanoes located at or in the marine realm, slopes continue below sea level and also subaqueous volcano flanks can be prone to mass wasting, often affected by terrestrial volcano built-up and activity. All these events potentially cause severe damage to society, directly or indirectly through secondary events like tsunamis. Successful strategies for mass-wasting hazard assessment and disaster risk reduction would imply integrated methodology for instability detection, mapping, monitoring and forecasting. This session invites research efforts that observe, quantify, or model volcano slope movements and failure. We encourage multidisciplinary contributions that integrate field-based on-shore and submarine studies, geomorphological mapping and account collection, analysis of the formation and transport of granular and dilute flows through fluid mechanics and sediment mechanics application, with advanced techniques, as remote sensing data analysis, geophysical investigations, ground-based monitoring systems and numerical and analogical modelling of volcano spreading, slope stability and runout volcaniclastic flows. *Conveners: A.
