| Session Description | Changes in groundwater levels, stream flow, water chemistry, and temperatures have been observed before and after earthquakes in seismically active areas. The processes of groundwater’s response for the observed anomalies are complex, involving interactions among crustal deformation, seismic shaking, permeability change, flow system changes causing chemicals and heat transfer, even inducing hazards related. Understanding these coupled processes is of great interest and importance to continuing efforts in recognizing earthquake precursors, earthquake hazards and lessening devastating consequences of earthquakes. This session involves the interdisciplinary researches among hydrology, geochemistry and seismology, and aims at providing a forum to exchange research ideas and results related to physical and chemical processes and related hazards of fluid flow in seismically active areas in either the near field or distant field from the epicenter. Sharing information and field observations at the forum will greatly promote the interdisciplinary research and help to efficiently utilize existing data from many different regions. Topics of interests include, but not limited to, (1) Reviews for earthquake hydrology and chemistry (2) Field observations and site-specific studies (3) Experiments and theoretical or numerical modeling of the coupled processes (4) Hydrological and geochemical changes before and after earthquakes (5) Chemical processes from faulting to observations of rocks in fault systems |
