[S-VC26] Active Volcanism

Tue. May 28, 2024 1:45 PM - 3:15 PM International Conference Room (IC) (International Conference Hall, Makuhari Messe)

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:Nobukazu Seama(Department of Planetology, Graduate School of Science, Kobe University), Akihiko Terada(Volcanic Fluid Research Center, Tokyo Institute of Technology)

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