Landslide hazard zones are determined through a combination of factors such as slope steepness, soil type, land cover, and historical landslide events. Geologists and engineers use techniques like field mapping, aerial imagery analysis, and geotechnical investigations to assess the stability of a particular area and identify potential landslide hazard zones. Geographic Information Systems (GIS) are also commonly used to map out and analyze landslide-prone areas based on various factors that contribute to the risk of landslides.
