Key Concepts and Principles

Landslide Hazard Zonation involves the identification and assessment of landslide hazards, considering various factors that influence their occurrence. These factors include geological conditions, slope steepness, soil properties, rainfall patterns, and human activities. By analyzing these factors, areas with a high susceptibility to landslides can be identified and mapped.

Mapping and zoning of landslide-prone areas is a crucial step in Landslide Hazard Zonation. This process involves the use of remote sensing techniques, geospatial data, and field surveys to create hazard maps. These maps categorize areas into different zones based on the level of landslide risk, ranging from low to high. Zoning helps in prioritizing areas for mitigation measures and land-use planning.

Various techniques and methodologies are used in Landslide Hazard Zonation, including Geographic Information System (GIS) analysis, landslide inventory mapping, slope stability analysis, and statistical modeling. These tools aid in the accurate assessment of landslide hazards and the creation of reliable hazard maps.
