[S-VC31] Active Volcanism

Wed. May 25, 2022 10:45 AM - 12:15 PM International Conference Room (IC) (International Conference Hall, Makuhari Messe)

convener:Yuta Maeda(Nagoya University), convener:Fukashi Maeno(Earthquake Research Institute, University of Tokyo), Takeshi Matsushima(Institute of Seismology and Volcanology, Faculty of Science, Kyushu University), Chairperson:Kohei Hotta(University of Toyama), Takeshi Matsushima(Institute of Seismology and Volcanology, Faculty of Science, Kyushu University)

This session discusses various aspects of active volcanisms including, but not limited to, rec
ent and historical eruptions, various phenomena associated with the volcanic activities, und
erground structures of the volcanoes, and developments of new instruments based on geop
hysical, geochemical, geological, and multidiscipline approaches. We also welcome studies o
n understanding and predicting the transitions of the eruptive activities from observational,
theoretical, and experimental approaches.
