[S-GL29] Mud Volcano and Geochemical, Geological, Geomorphological, and Biological-related phenomena

Thu. May 24, 2018 3:30 PM - 5:00 PM A03 (Tokyo Bay Makuhari Hall)

convener:Miho Asada(Japan Agency for Marine-Earth Science and Technology), Tomohiro Toki(Faculty of Science, University of the Ryukyus), Akira Ijiri(国立研究開発法人海洋研究開発機構, 共同), Takeshi Tsuji(Department of Earth Resources Engineering, Kyushu University), Chairperson:Toki Tomohiro, Tsuji Takeshi

Mud Volcano (MV) is one of geological feature that observed over the world. The MV brings fluid and sediment from several km below the ground. A complete understanding of MVs are desired due to a point of carbon cycle from earth's depth to surface, migration of deep subsurface biosphere, impact on greenhouse warming, social disaster, civil engineering, and so on for examples. However, MVs are still not understood enough because of its diverseness.
We propose this MV session to concern MV studies from various methods, fields, and time scale, and to discuss on MVs from a multilateral perspective. We welcome scopes of discussion include their relationships to earthquakes, possible utilization for resources, as well as scientific studies on mechanisms of MVs, to understand the MV phenomena.
