Fig. 1From: Shallow hydrothermal reservoir inferred from post-eruptive deflation at Ontake Volcano as revealed by PALSAR-2 InSARMap of the study area. The inset is a close view of the summit area and corresponds to the area of interferograms (Figs. 3, 4) and modeling (Fig. 5). Most of the hydrothermal activity at the Ontake Volcano occurs around the Jigokudani Valley (indicated with the dashed line). The black diamonds indicate GNSS stations deployed around the edifice of the Ontake Volcano. Eruptive vents are also markedBack to article page
