Landslides cause billions of dollars in damages and thousands of deaths and injuries globally each year. Generating landslide inventory, landslide susceptibility and landslide risk maps in landslide prone areas are the essential steps for landslide risk assessment and management.

Landslide susceptibility is a critical step for landslide risk management. The methodology of GIS-based landslide susceptibility study varies from direct mapping, to heuristic, deterministic, stochastic and probability analyses. Despite the different approaches used in these methods, all of them are founded upon a common procedures which include mapping of landslides over a target region; identification and mapping of a set of contributing factors to slope instability; estimation of the relative contribution of these factors in generating slope-failures; classification of the final land surface into zones of different degrees of hazard by different analysis methods; and verification of the landslide susceptibility map. The recently developed Ground-based interferometric radar (GBIR) technique advances the landslide study to a new level. This presentation focuses on landslide susceptibility study by using various GIS-based methods and GBIR technique.
