Fig. 3From: InSAR analysis for detecting the route of hydrothermal fluid to the surface during the 2015 phreatic eruption of Hakone Volcano, JapanTemporal change of local swelling at Owakudani (modified from Doke et al. 2015a). Interferograms are obtained from InSAR pairs in the same orbit with Pair I (Path 18). Color shows wrapped phase difference between 0 and +2π radian. Phase difference of 2π radian corresponds to a slant-range change of 11.9 cm. Contour intervals are 25 m in heightBack to article page
