Land usage increases along with the rising population growth and development of a region. This leads to a greater potential for natural disasters caused by land degradation, especially on land with relatively steep to steep slopes. The research area is located in Warungkiara District, Sukabumi Regency, West Java Province. Geographically, Warungkiara lies between -6.910833° S --7.000833 o S and 106.712222° E -106.802778 o E. The study was conducted using primary fieldwork data and supporting

This research intends to assess the potential of landslide disaster based on quantitative geomorphology and land use data with hopes that it can be used as a reference for land management policies and for zoning landslide prone areas. Based on the analysis of quantitative geomorphology and land use data, areas with high likelihoods of landslide are found in research area zones 1, 5 and 6 which both have >40% grade. Areas with potential for landslides are found in zones 2 and 3 with grades of 15-25%. From our observations, areas with landslide potential have ineffective land management. It is recommend that land use in landslide prone areas should be reviewed, with a greater emphasis on land use that can reduce landslide potential. Human settlements and vital human activities should avoid areas of potential landslide disaster.
