Landslide Atlas of India

The National Remote Sensing Centre (NRSC), Indian Space Research Organization (ISRO), Department of Space has also published the Landslide Risk Exposure Ranking of different districts of Himachal Pradesh as a part of the Landslide Atlas of India (2023). These databases are made available for use by National and State Disaster Management Authorities for planning and taking appropriate action to tackle various extreme weather events.

About the Report

This Atlas provides the details of landslide present in Landslide provinces of India including damage assessment of specific landslide locations. Geospatial landslide inventory database consisting of ~80,000 landslides in India mapped by NRSC/ISRO under its DMS programme during the 1998-2022 period is reported here. The database covers landslide vulnerable regions in 17 states and 02 UTs of India in the Himalayas and Western Ghats. The database includes three types of landslide inventory - seasonal, event-based and route-wise for the 1998-2022 period. Seasonal inventory contains pan-India landslide database corresponding to the 2014 and 2017 rainy season in India. Event-based inventory contains details of some of the major triggering events such as Kedarnath and Kerala disasters, and Sikkim earthquake as well as few large valley blocking landslides. Routewise inventory contains details of landslides along selected routes of tourist and pilgrimage importance.Satellite data of high to very high resolution such as IRS-1D PAN+LISS-III, Resourcesat-1, 2 and 2A LISS-IV Mx, Cartosat-1 and 2S, data from International satellites (Sentinel-1&2, Pleiades and WorldView) and Aerial images were used in the mapping of landslides. Some of the mapped landslides were validated in the field using mobile App and news reports. The database were used to rank 147 districts in 17 states and 02 UTs of India for their exposure to landslides in terms of key socio-economic parameters. Lastly advanced techniques in landslide detection, modeling and prediction are also explained.
