Detailed explanation-1: -Landslide hazard mapping/zonation is a division of terrain into zones that are basically characterized by the spatial and temporal probability of landslide occurrence that includes description of location, volume, and prediction of future landslide occurrence in an area (Fell et al. 2008; Fell et al. 2007; AGS 2000).
Detailed explanation-2: -The main step for landslide hazard mapping is data collection and preparation of a spatial database from which relevant factors can be extracted. The main feature of this method is comparing the possibility of landslide occurrence with observed landslides.
Detailed explanation-3: -But even more important, the information must be perceived as explaining a hazard that may adversely affect life, property, or socioeconomic activities. This can be accomplished by providing three elements-location, likelihood of occurrence (frequency or return period), and severity.
Detailed explanation-4: -A hazard map is a map that highlights areas that are affected by or are vulnerable to a particular hazard. They are typically created for natural hazards, such as earthquakes, volcanoes, landslides, flooding and tsunamis.
