[SCG60-04] Estimate of hydraulic properties of the crust - An example from water discharge by Naganoken-Hokubu earthquake
Keywords:Naganoken-Hokubu earthquake, Kamishiro Fault, Fluid discharge, Fracture zone, Hydroraulic property
Post-seismic fluid discharge was observed from the fracture zone of the Kamishiro Fault. Our team has been observed and monitored the flow amount and chemical characteristics of the fluid for about 5 months from one week after the earthquake.
In this presentation, we describe the occurence of earthquakes and its relation to the hydraulic propertes and discuss about the governing equations of fluid flow in fracture zone ofthe Kamishiro Fault.
