Linear surface ruptures around Suizenji Park, Kumamoto city center. a A high-pass-filtered up–down displacement map made by three-dimensional (3-D) analysis (Morishita et al. 2016) using ALOS-2 image pairs 3, 8, 9 and 10 in Table 1. Red and blue areas represent up and down, respectively. The contour interval is 1 cm. Red solid lines show the identified linear surface ruptures. Ticks of the red lines show the lower side of each displacement. The area is shown in Fig. 2a. b Red solid lines show the identified linear surface ruptures. Ticks of the red lines show the lower side of each displacement. Topography is drawn using a DEM
