(a) Locations of the landslide (red line) and RSL (blue lines) in Palikir crater; (b) HRSC DEM covering the landslide, with colored lines indicating the locations of the elevation profiles; (c) Elevation profiles derived from the landslide and non-landslide regions on the DEM. (d–f) show numerical modeling of the landslide at the initial, middle, and final stages, respectively, with different displacement d. p is the pore pressure due to a possible fault within the bedrock resulting from uplifting brines. (g) shows the actual profile derived from the HRSC DEM, which matches the profile of the simulated landslide in (f). The software ArcGIS 10.6 (https://www.esri.com/) was used to create the maps in (a,b).
