[S-VC26] Active Volcanism

Tue. May 28, 2024 10:45 AM - 12:15 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:Takeshi Tameguri(Sakurajima Volcano Research Center,Disaster Prevention Research Institute, Kyoto University), Ryohei Kawaguchi(Meteorological Research Institute)

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.
