Figure 5From: Co-seismic landslide topographic analysis based on multi-temporal DEM—A case study of the Wenchuan earthquakeCo-seismic topographic changes. Distribution of Pre-earthquake and post-earthquake hillslope (a), roughness (b) and slope aspect (c). The medium topography are roughened and steepened, however the steepest and roughest topography are smoothed by the Wenchuan earthquake. The slope aspect is almost unchanged.Back to article page
