As the terrain “Laipuitlang Slide” is a great example of human induced is of rugged nature composed of several unconsolidated factor (Verma, 2014). Still the area is lacking proper sedimentary formations, it is prone to frequent slope failures comprehensive studies at micro-level to understand the main causing massive landslides thereby disruption to traffic, damage cause in order to reduce the risk of this particular hazard at to property and loss of lives occurred at many sections in and places. GIS based landslide susceptibility mapping by around Aizawl city. An attempt has been made in this study to identify the areas of slope failure causing high magnitude heuristic and bivariate methods is useful to identify the areas landslides between Aizawl city and Lengpui airport by numerical prone to landslides more precisely (Prabhin Kayastha et al., rating scheme of landslide hazard evaluation factors (LHEF) 2013). Spatial probabilistic modeling for generation of slope with the help of the advanced tools of ArcGIS software. Five failure probability hazard map using geographical information zones of landslide hazards such as very high, high, moderate, low systems is much useful to identify the areas of slope failure at and very low have been identified along this road section.
