[S-VC43] Active Volcanism

Tue. May 26, 2026 3:30 PM - 5:00 PM Convention Hall (CH-A) (International Conference Hall, Makuhari Messe)

Chairperson:Tsunomori Fumiaki(Geochemical Research Center, Graduate School of Science, University of Tokyo), MORI TOSHIYA(The University of Tokyo)

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.
This session is categorized as a J-session; however, slides and posters may be prepared in English, and presentations in English are also welcome.
