[S-VC29] Dynamics of volcanic eruptions and their physical and chemical processes

Thu. May 25, 2023 9:00 AM - 10:15 AM 303 (International Conference Hall, Makuhari Messe)

convener:Naoki Araya(Department of Earth Science, Graduate School of Science, Tohoku University), Atsuko Namiki(Graduate School of Environmental Studies, Nagoya University), Ryo Tanaka(Hokkaido University,Institute of Seismology and Volcanology), Dan Muramatsu(Earthquake Reserch Institute, The University of Tokyo), Chairperson:Naoki Araya(Department of Earth Science, Graduate School of Science, Tohoku University), Dan Muramatsu(Earthquake Reserch Institute, The University of Tokyo)

Multiple processes are involved in volcanic eruptions, including magma accumulation at depth, vesiculation and crystallization during magma ascent in volcanic conduits, and dispersion of volcanic products. A broad range of approaches is required to elucidate these processes and better understand the factors that govern the physics of eruptions. We welcome contributions from geophysical observations of active/quiet volcanoes, petrological/geochemical measurements of eruptive products, theoretical approaches, numerical simulations, laboratory experiments, and interdisciplinary studies that combine the above approaches.
