a Location map of Kusatsu-Shirane Volcano, Japan. The red triangle represents the Kusatsu-Shirane Volcano. b Simplified geological map of Kusatsu-Shirane Volcano (KSV) (after Uto et al. 1983). The distribution of lava is colored by its eruptive stage. Neogene lava is the oldest. Pyroclastic cone includes volcaniclastic deposits of Motoshirane Pyroclastic Cone, Ainomine Pyroclastic Cone, and Shirane Pyroclastic Cone. Black triangles represent three pyroclastic cone groups. The white square indicates the area shown in Fig. 2. The solid square labeled Boring site indicates the location of the geothermal exploration borehole (Gunma Prefecture 1989)
