Surface displacement maps from InSAR analysis of ALOS-2/PALSAR-2 images. a 2015/6/18–2015/7/2 pair (Pair I), b 2015/6/7–2015/7/5 pair (Pair II), c 2015/5/15–2015/7/10 pair (Pair III), d 2015/5/28–2015/8/6 pair (Pair IV). Positive (red colored) areas indicate displacement toward the satellite, and negative (blue colored) areas show displacement away from the satellite. A, B, and C show displacement areas mentioned in the text. KM and SU show the summits of Kamiyama and Sounzan, respectively. Parameters details of each pair are shown in Table 1
