[S-CG62] Rheology, fracture and friction in Earth and planetary sciences

Thu. May 29, 2025 5:15 PM - 7:15 PM Poster Hall (Exhibition Hall 7&8, Makuhari Messe)

convener:Osamu Kuwano(Japan Agency for Marine-Earth Science and Technology), Hiroaki Katsuragi(Department of Earth and Space Science, Osaka University), Sando Sawa(Deparment of Earth Science, Graduate School of Science, Tohoku Univeristy), Dan Muramatsu(Earthquake Reserch Institute, The University of Tokyo)

This session aims to join people from various research areas in the earth and planetary sciences and to stimulate discussion beyond the boundaries of each research area. Our goal is to deepen our understanding of dynamics in geosciences by looking over whole areas in the earth and planetary sciences from the viewpoint of PHYSICS OF DEFORMATION, FLOW, AND FRACTURE. We welcome any field (e.g., earthquake, volcano, earth surface, crust, mantle and the core, and other planets and satellites) and any approach (e.g., laboratory experiments, numerical simulations, field observations, and theories).
