This study was carried out to identifiy topographical feature of mountain areas, where the occured the shallow landslide. In this study, the topographic features were classified as slope type, zero order basin, and micro-topography. The criteria of topography are curvature, upslope contributing area and slope. The study site was Mt.Umyeon, where landslide occurred in 2011, and the shallow landslide site was interpreted using aerial photographs. The interpreted collapsed sites were classified into 5 types. As a result of the study, 70 collapsed sites were identified, the average area was 67.27m2 and the average slope was 29.52°. The slope type can be classified into 9 types based on the plan and profile curvature, and 48.6% of the shallow landslide occurred in the convergence(in plan curvature)-flat type(in profile curvature). The zero order basin was formed at an upslope contributing area of less than 17,000m2 and 67% of the shallow landslide occurred at an upper slope contribution area of less than 500. The micro-topography can be confirmed by turning line of slope, and 81% of shallow landslide occurred on the side slope of slope above 25°..
