2-2-2-2-2-2-2-2-2-2-2-2-2 From: CAUDRON Corentin <corentin.caudron@xxxxxx> Interested in shaping the future of research on phreatic eruptions? Please submit an abstract to this hot topic and discuss past, ongoing and especially future ways to improve forecasting *Gas-driven Eruptions: Characteristics, Processes and a dire need for Forecasting* Recent deaths and/or injuries attributable to gas-driven eruptions from Whakaari, Ontake, Ruapehu, and Raoul volcanoes (and numerous others) point to a compelling need to better understand the physico-chemical processes operating within the magmatic-hydrothermal environments which promote these eruptions. These eruptions are particularly dangerous as they are typically unheralded and non-magmatic, and thereby escape detection by conventional means. Moreover, the chemical and physical processes serving to reduce permeability and increase pore pressures, do so only slowly in the shallow subsurface, most often evading discerning eyes. This session invites multidisciplinary (geochemical, geophysical, experimental and/or numerical) studies of pre- through to post-eruption datasets which seek to characterise the processes operating within active systems. The goal is to foster comparison of time series variations of what authors regard as key parameters within their data. Hopefully, common threads amongst system behaviours will advance the proposition that we will one day be able to forecast these dangerous eruptions. Confirmed speaker: John Stix. Conveners: Bruce Christenson, Felipe Aguilera and Corentin Caudron 2-2-2-2-2-2-2-2-2-2-2-2-2 ------------------------------
