Fig. 6From: InSAR analysis for detecting the route of hydrothermal fluid to the surface during the 2015 phreatic eruption of Hakone Volcano, JapanResult of the single open crack model inversion. a Modeled surface displacements, and b residuals between model and observation for Pair I. c Modeled surface displacements, and d residuals between model and observation for Pair II. B and C indicate displacement areas mentioned in the text. KM and SU show the summits of Kamiyama and Sounzan, respectively. Offset parameters were 2.78 mm for Pair I and –13.70 mm for Pair II. The red rectangle shows the estimated open crack, the parameters of which are listed in Table 2. Pair II was not used as an input dataset during the inversionBack to article page
