[S-CG75] [JJ] Crustal fluids and deformation

Sun. May 21, 2017 1:45 PM - 3:15 PM 106 (International Conference Hall 1F)

convener:Naoji Koizumi(School of Environmental Science,the University of Shiga Prefecture), Koji Umeda(Hirosaki University), Norio Matsumoto(Tectono-Hydrology Research Group, Geological Survey of Japan, National Institute of Advanced Industrial Science and Technology (AIST)), Hidemi Tanaka(School of Science, The University of Tokyo), Chairperson:KOJI UMEDA(Hirosaki University), Chairperson:NAOJI KOIZUMI(School of Environmental Science,the University of Shiga Prefecture)

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 inc luding 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.
