Micro-Zonation of Landslide Hazards Between Aizawl City and Lengpui Airport, Mizoram, India, Using Geoinformatics

Mizoram has highly undulating terrain with steep slopes and deep valleys in its topographical set-up. As the terrain is of rugged nature composed of several unconsolidated sedimentary formations, it is prone to frequent slope failures causing massive landslides thereby disruption to traffic, damage to property and loss of lives occurred at many sections in and around Aizawl city. An attempt has been made in this study to identify the areas of slope failure causing high magnitude landslides between Aizawl city and Lengpui airport by numerical rating scheme of landslide hazard evaluation factors (LHEF) with the help of the advanced tools of ArcGIS software. Five zones of landslide hazards such as very high, high, moderate, low and very low have been identified along this road section.
