Scope | 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. | |
