Landslide Hazard Zonation Mapping Techniques on Himalayan Region in India: A Survey

This review article is focused on the modern mapping techniques for creating a near-accurate landslide hazard zonation (LSZ) map focused on the different parts of the Himalayan Mountain region in India. The necessity of an LSZ map has been discussed by some given examples showing the vulnerability that comes with every landslide. As one of the youngest folded mountain ranges, The Himalayas are very much prone to landslides, with the development of modern technologies, the way of research has also transformed. In this article, the focus is identifying some recent techniques based on GIS and Remote sensing technologies which proves the accuracy and necessity of more research work. There are many areas that are vulnerable to landslides but completely untouched. The focus is to merge different techniques to create an understanding of how the technology can be a useful tool to create more accurate LHZ maps for different locations.
