[S-VC30] Volcanic and igneous activities, and these long-term forecasting

Thu. Jun 3, 2021 3:30 PM - 5:00 PM Ch.25 (Zoom Room 25)

convener:Takeshi Hasegawa(Department of Earth Sciences, College of Science, Ibaraki University), Teruki Oikawa(GSJ, National Institute of Advanced Industrial Science and Technology), Daisuke MIURA(Department of Physical Science, Graduate School of Science, Osaka Prefecture University), Nobuo Geshi(Geological Survey of Japan, The National Institute of Advanced Industrial Science and Technology), Chairperson:Takeshi Hasegawa(Department of Earth Sciences, College of Science, Ibaraki University), Yuki Yasuda(Institute of Seismology and Volcanology, Faculty of Science, Hokkaido University)

This session focuses on generation and accumulation processes of magmas, 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.
