[S-VC34] Volcanic and igneous activities, and these long-term forecasting

Tue. May 27, 2025 3:30 PM - 5:00 PM Convention Hall (CH-B) (International Conference Hall, Makuhari Messe)

convener:Takeshi Hasegawa(Department of Earth Sciences, College of Science, Ibaraki University), Shimpei Uesawa(Central Research Institute of Electric Power Industry), Koji Kiyosugi(Department of Planetology, Graduate School of Science, Kobe University), Teruki Oikawa(GSJ, National Institute of Advanced Industrial Science and Technology ), Chairperson:Koji Kiyosugi(Department of Planetology, Graduate School of Science, Kobe University), Shota Watanabe(Mount Fuji Research Institute)

This session focuses on generation and accumulation processes of magma, magma-crust interaction and degassing, and modes of eruption, long-term forecast of eruption, dispersal and emplacement of the volcanic products. The discussion spans petrological, geochemical, geophysical, and geological processes related with volcanic activity and products in the past, the present and the future.
