[S-CG62] Crustal fluids and deformation

Wed. May 23, 2018 5:15 PM - 6:30 PM Poster Hall (International Exhibition Hall7, Makuhari Messe)

convener:Naoji Koizumi(School of Environmental Science,the University of Shiga Prefecture), Koji Umeda(Hirosaki University), Norio Matsumoto(産業技術総合研究所地質調査総合センター地震地下水研究グループ, 共同), Hidemi Tanaka(School of Science, The University of Tokyo)

We will provide an opportunity to discuss about observation and modeling of crustal fluids. Topics of interests include, but not limited to
(1) a field of physics and chemistry of fault fluids, which is related to earthquake occurrences and researches physical and chemical changes of the fluids caused by crustal deformation including earthquakes,
(2) a field of earthquake hydrology, which estimates crustal deformation from level, pressure and chemistry of groundwater using poro.elastic theory, and
(3) a field of chemistry of crustal fluids, which concerns chemical and isotopic features of the crustal fluids and try to estimate the flux of them.
