Landslide Hazard Zonation along NH 54A from Lunglawn to Zotlang in Lunglei, Mizoram, India

The state of Mizoram in Northeast India is a landslide prone one. It is a landlocked state bordering Myanmar to its east and Banglasesh to its west and south and the Indian state of Assam to the north. In recent years , Lunglei witnessed two devastating landslides in 2018 and 2019 with numerous losses of life and property.The losses incurred from the natural and man made disasters in other areas in the state too have led to tremendous losses of money to the exchequer, particularly landslides. Many of the landslides are result of combination of geology, geomorphology, topography and anthropogenic activities.The seasonal rains several are triggering cause of these landslides on many occasions especially during the monsoons.
Lanslides in general have caused numerous casualities with immense economic losses and they will continue so in the hilly and mountainous region like Mizoram unless sound and scientific decisions and measures are not adopted by the people and the authorities. Identification of landslide hazards of urban areas situated on the top of mountainous ridges like Lunglei, is essential for minimizing the lossess due to landslides and other mass movements. This study comrises an area of 8.86.sq.kms traversing the LUnglei town from Lunglawn to Zotlang localities with the NH 54A being buffered with 500m on both sides in homogenous domains and the obtained results classify the study area into a potential landslide hazard threat, they can cause in future.
