[S-CG67] Crustal fluids and deformation

convener:Yuichi Kitagawa(Tectono-Hydrology Research Group, Geological Survey of Japan, National Institute of Advanced Industrial Science and Technology), Naoji Koizumi(School of Environmental Science,the University of Shiga Prefecture), Koji Umeda(Hirosaki University), Fumiaki Tsunomori(Geochemical Research Center, Graduate School of Science, 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 poroelastic 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.
