Abstract The 1933 Dexi Mw 7.5 earthquake triggered numerous rock slides within Songpinggou meizoseismal area. To systematically describe the topographic and geological controls on these landslides，208 landslides including 48 large landslides(≥0.1 km2) are recorded by remote sensing，LiDAR，unmanned aerial vehicle(UAV) and field investigations. A series of indicators containing landslide type，frequency and ratio of frequency，area and ratio of area，non-weighted landslide kernel density and area-weighted landslide kernel density are selected to analyze the topographic(slope aspect，elevation，local relief and slope gradient) and geological(slope structure and lithological combination) characteristics of the landslide location. Results show that landslides are concentrated in the terrain with slope gradient of 50°–60°，local relief exceeding 370 m and elevation of 2 000–3 000 m. Notable differences of slope structure exist between left bank(reverse slope：3%) and right bank (reverse slope：41%) in the river valley(Waerbao-Jiaochang section). The proportion of landslides in the left bank is 85%，higher than 15% in the right bank. In the left bank，the proportion of planar and wedge landslides reaches 81% and no topple-type landslides are found，while the proportion of topple-type landslides in the right bank arrives at 38%. Rockfalls and debris slides have the same proportion in the left and right banks，9% and 12% respectively. More than 60% of plane and wedge landslides mainly occur in thick-megathick layered sandstone interlayered with thin layered phyllite such as Zagunao Formation，Zhuwo Formation and C+P (Carboniferous - Permian strata)，while more than 70% of rockfalls and debris slides are mainly distributed in Xinduqiao Formation and Bocigou Formation with geological characteristics of thin slate interlayered phyllite. The largest landslide area in thick-layer lithology is 7.89 km2，and the average area value of this lithological combination is 7 times more than the thin-layer type. It is pointed out that the slope structure and the lithological combination have mainly influences on landslide frequency，type and size. The topography of Songpinggou valley formed by rapid crustal uplift and river erosion，with significant elevation difference，high local relief and steep gradient，provides favorable topographic conditions for landslide distribution extent and concentration. The findings provide a basis for landslide identification and prediction from topographic and geological conditions.
