Fig. 8From: InSAR analysis for detecting the route of hydrothermal fluid to the surface during the 2015 phreatic eruption of Hakone Volcano, JapanResult of the inversion estimating the point pressure source beneath the Owakudani. a Subsampled displacement data of Pair I prepared for the inversion. b Modeled surface displacement. Offset parameter was 5.34 mm. RMS of the residual between observation and model was 1.19 cm (RMS of the original dataset was 2.34 cm). Green circles show the steam wells that experienced abnormal blowout during the 2015 unrest. Red and yellow circles show the newly formed craters and fumaroles, respectively. The “X” mark shows the location of the estimated point pressure source, the parameters of which are listed in Table 4Back to article page
