Temporal 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 height
