Fig. 6From: Permeability-control on volcanic hydrothermal system: case study for Mt. Tokachidake, Japan, based on numerical simulation and field observationVolume fraction of liquid phase in the pore space calculated for the uniform permeability structure of Case A and Case B, just before introducing hydrothermal fluid injection at the base of the conduit. Unsaturated regions occur above 900 m elevationBack to article page
