Examples of landslides triggered by the heavy rainfalls of 2012 (black polygons) and the 2016 Kumamoto earthquake (shown in b) on orthorectified images acquired in a March 2016 and b May 2016. c Difference of digital surface models (DSMs) between March and May 2016 (blue represents a decrease in DSM). d Profile of the slope on which the landslide was located in April 2004 (gray dashed line), March 2016 (black line), and May 2016 (blue line), shown by the black profile line (P1–P2). The arrow in d shows the scarp of the rainfall-induced landslide in 2012. The slope profile in April 2004 was derived from lidar-based DSM with a spatial resolution of 2.0 m (Saito et al. 2016)
