摘要：For landslide susceptibility mapping, this study applied frequency ratio to Aghnashini river catchment ofUttara Kannada district of Karnataka, India using Geographic Information System (GIS). Landslide locationswere located in the study area by intensive field surveys; and a spatial database was constructed fromtopographic maps, soil type, forest cover, geology and land cover. The frequency ratio factor’s rating forlandslide susceptibility mapping was evaluated. Then the landslide susceptibility map was verified andcompared with known landslide locations. The method can be used to reduce hazards associated withlandslides and to landuse change planning.
