[S-VC44] Magmatism and volcanic dynamics on subduction zone

Thu. May 24, 2018 10:45 AM - 12:15 PM A08 (Tokyo Bay Makuhari Hall)

convener:Yujiro Suzuki(Earthquake Research Institute, The University of Tokyo), Hitomi Nakamura(Department of Solid Earth Geochemistry, Japan Agency for Marine-Earth Science and Technology), Yu Iriyama(国立研究開発法人　防災科学技術研究所), Chairperson:Nakamura Hitomi(Japan Agency for Marine-earth Science and Technology), Iriyama Yu(National Research Institute for Earth Science and Disaster Resilience (NIED))

Subduction zones are characterized by magmatism and volcanism caused by magma generation, magma transportation and storage, and volcanic eruption. These magmatic process and volcanic dynamics have been investigated using laboratory experiments and sophisticated numerical modelings. Recent progress of observation techniques has revealed the structures under volcanoes. Besides, the studies based on seismological observations and geochemical analyses try to determine the spatial and temporal scale of magmatic activity and explain the process of magma generation. This session aims to discuss the latest studies about magmatism and volcanic dynamics from various perspectives and integrate these understandings.
