Landslide thickness and lidar change maps. Landslide thickness inversion maps from (a) lidar surface velocity and (b) InSAR surface velocity maps. Orange lines show 5 m thickness contours in (a,b). (c) Vertical elevation change derived from pre- (2016) and post-collapse (2018) lidar point cloud. Orange lines show 10 m contours in (c). Positive values correspond to material deposit after failure. Maps are draped on pre-collapse lidar hillshade. (d–e) Down slope and cross slope ground surface and slip surface elevation profiles. The down slope profile for the slip surface is scaled by 2 × thickness in the vertical direction. Dashed vertical gray lines show where the profile crosses the catastrophic failure scarp. Insets show location of profiles.
