[S-VC29] Volcanic and igneous activities, and these long-term forecasting

Mon. May 23, 2022 1:45 PM - 3:15 PM International Conference Room (IC) (International Conference Hall, Makuhari Messe)

convener:Takeshi Hasegawa(Department of Earth Sciences, College of Science, Ibaraki University), convener:Shimpei Uesawa(Central Research Institute of Electric Power Industry), Teruki Oikawa(GSJ, National Institute of Advanced Industrial Science and Technology ), convener:Koji Kiyosugi(Organization of Advanced Science and Technology, Kobe University), Chairperson:Akira Baba(Mount Fuji Research Institute), Shohei Shibata(Graduate school of science and technology, Ibarbki University)

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.
