Abstract


North Toraja Regency is an area that is prone to landslides with a potential zone of medium to high ground movement, which has resulted in damage to land transportation routes between districts being cut off, damage to buildings, and loss of lives. The focus of this research is to determine the level of vulnerability and map the class of landslide hazards in the North Toraja Regency. This type of research is descriptive qualitative with Geographical Information Systems (GIS) approach and then analyzed by overlay and scoring (weighting). Based on data processing, the study produced a landslide hazard map in North Toraja Regency with five classes of vulnerability, namely: very low area of 58,049 km2 (50%), low area of 118,087 km2 (11.18%), medium area of 256,057 km2 (22.07%), rather high area of 195,872 km2 (16.07%), very high area of 11,972 km2 (1.03 %).
