Scope 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.
