[S-VC32] Dynamics of volcanic eruptions and their physical and chemical processes
Thu. May 26, 2022 5:15 PM - 6:45 PM Exhibition Hall 8
A Volcanic eruption is a hazardous phenomenon that results from a sequence of coupled processes, including storage in the subsurface and ascent to the surface. The volcanic gas exsolving from the ascending magma generates bubbles, which influence both the potential energy of the magma (density) and its resistance to flow (viscosity). Bubbles can sometimes deform and/or fragment the surrounding magma, leading up to explosive eruptions that develop volcanic plumes and/or pyroclastic flows. A broad range of approaches is required to tackle these processes and better understand the factors that govern the physics of explosive eruptions. We welcome contributions from interdisciplinary approaches, including, geophysical observations of active/quiet volcanoes, geochemical measurements of eruptive products, theoretical approaches, and numerical simulations, and laboratory experiments designed to explore the fundamental processes underlying explosive volcanism.
