[S-VC28] Active Volcanism

Sat. Jun 5, 2021 10:45 AM - 11:30 AM Ch.25 (Zoom Room 25)

convener:Yuta Maeda(Nagoya University), Takahiro Miwa(National research institute for earth science and disaster prevention), Takeshi Matsushima(Institute of Seismology and Volcanology, Faculty of Science, Kyushu University), Chairperson:Urumu Tsunogai(Graduate School of Environmental Studies, Nagoya University), Takeshi Ohba(Department of chemistry, School of Science, Tokia 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.
