Nakano et al. (2018) et al. reported that tectonic surface deformation appeared along Zogahana Fault, northern part of Aso Caldera, Japan. This study used ascending ALOS-2 data (Path130 Frame650) measured on 25 Feb, 16 Jun, and 20 Oct in 2016 and descending ALOS-2 data (Path23 Frame2950) measured on 7 Mar and 18 Apr in 2016) and performed 2.5-D analysis (Fujiwara et al., 2000) . As a result, it was found that north-dipping and right-lateral deformation was detected along Zogahana Fault, same as Nakano et al. (2018).
