[SCG61-06] Observation of co- and post-seismic fluid migration in and around Kamishiro Fault, Naganoken-Hokubu earthquake
Keywords:Naganoken-Hokubu earthquake, Kamishiro Fault, Fluid, Hot spring, Fracture zone, hydrological characteristics
Right before and after the earthquake, pre-, co- and post-seismic fluid migration was observed at around the Kamishiro Fault. Our team has been observing and monitoring the flow amount and chemical characteristics of the fluid from one week after the earthquake to present and still continue observation.
In this presentation, we consider the driving mechanism for fluid flow and hydrological characteristics of the fracture zone of the Kamishiro Fault.
