4-4-4-4-4-4-4-4-4-4-4-4-4 From: Alessandro Bonforte <alessandro.bonforte@xxxxxxx> Dear colleagues, we kindly invite you to submit your abstracts to the session "1.11: Large- to small-scale instability-to-collapse processes and mass wasting: dynamics, models and hazard implications" of the next Cities on Volcanoes conference that will be held in Heraklion (Crete) from May 23 to 27. The deadline for submitting the abstract is January 25, 2020. Session 1.11: https://pcoconvin.eventsair.com/volcanoes11/session01#S111 Abstract submission: https://pcoconvin.eventsair.com/volcanoes11/abstracts Session description: S1.11 > Large- to small-scale instability-to-collapse processes and mass wasting: dynamics, models and hazard implications Conveners: Rosanna Bonasia, Alessandro Bonforte, Federico Di Traglia, Felix Gross, Matteo Roverato Mass-wasting in volcanic environments, both on-shore and subaqueous, comprises a wide spectrum of phenomena, from large lateral collapse to shallow debris remobilization that represent a major threaten for societies. Slope stability ranges from slow and continuous to sudden and catastrophic and the interpretation of such events is challenged by the complex and evolving interactions between tectonic, magmatic, fluid, and gravitational processes. The moving masses can behave in different ways depending on water content and flow rheology and can demonstrate different modes from flank spreading or collapse to granular or viscous flow. Water plays an important role in the transport and emplacement mechanisms of the flows, enhancing their run-out and destructive power. Many volcanoes worldwide are located in tropical, high-precipitation environments or are covered by snow or glaciers, which exacerbates the potential for landslides, lahars, and debris avalanches. In most cases, volcano 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. This session encourages multidisciplinary contributions from both earth and social scientists that critique, explain and discuss how high-resolution vulnerability and risk analysis and volcanic mass flow studies are necessary to reduce disaster risk within vulnerable populations. We expect contributions that integrate field-based geological and geochemical studies, geomorphological mapping, geophysical investigations, remote sensing and analytical, numerical and analogical modelling. 4-4-4-4-4-4-4-4-4-4-4-4-4 ============================================================== Volcano Listserv is a collaborative venture among Arizona State University (ASU), Portland State University (PSU), the Global Volcanism Program (GVP) of the Smithsonian Institution's National Museum of Natural History, and the International Association for Volcanology and Chemistry of the Earth's Interior (IAVCEI).
