Abstract
West Sumatra is one province prone to natural disasters, including landslides. Changes in environmental characteristics such as slope geometry conditions, vegetation density, and changes in land use will affect the coefficient of runoff and rainwater filtration, thus triggering landslides. In addition, natural factors such as geological conditions, soil types, rainfall, seismicity, and others significantly affect the potential for landslides. This study aims to analyze the potential for landslides due to changes in the characteristics of the physical environment in the Kuranji Watershed, Padang. Data on the characteristics of the physical environment and its changes were collected from various sources and then analyzed to determine changes in the characteristics of the physical environment in the Kuranji watershed, Padang. Mapping of the physical characteristics of the research area includes soil type, rainfall, geological conditions, seismicity factors, the topography of the area, changes in land use and vegetation density, and their influence on the potential for landslide hazards. The study results are thematic geospatial information on landslide-prone areas in the Kuranji watershed, Padang. This mapping can be used as a reference for disaster mitigation and spatial planning in Padang City, especially in the Kuranji watershed.
