[S-VC31] Active Volcanism

Wed. May 25, 2022 3:30 PM - 5:00 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:Kenta Yoshida(Japan Agency for Marine-Earth Science and Technology), Fukashi Maeno(Earthquake Research Institute, University of Tokyo)

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.
