      To clarify the characteristics of scale and occurring position of earthquake-induced landslides within pre-existing landslide topography, we investigate landslides induced by the Mid-Niigata Prefecture earthquake and pre-existing landslide topographies. The results show that the scale of earthquake-induced landslides tends to smaller than that of pre-existing landslide topography ; the scale of earthquake-induced landslides were likely to be influenced by basic geology and geological structure of the sites ; the landslides occurred inside pre-existing landslide topography tend to larger than that occurred outside of pre-existing landslide topography ; much of the earthquake-induced landslides occurred as partial area within pre-existing landslide topography, mostly at the lower part of pre-existing landslide topography, due to considerable influence by river erosion.
