Landslides cause huge damages, particularly along pilgrim routes. ISRO prepared Landslide Hazard Zonation maps for pilgrim routes in Himachal Pradesh, Uttarakhand and Meghalaya.In addition, ISRO is also preparing seasonal landslide inventory on regular basis.These satellite based inputs are very useful for preparedness.
Experimental Landslide Early Warning System for Rainfall Triggered Landslides is carried out for the following routes namely Rishikesh-Badrinath, Rishikesh-Uttarkashi-Gaumukh,Chamoli-Okhimath Rudraprayag-Kedarnath and Pithoragarh-Malpa in Uttarakhand during specific seasons.
Near real time information on landslides is derived regularly during major landslide events in the country and disseminated through Bhuvan geoportal. Areal extent of landslide is also estimated using satellite data and DSMs. In addition, in case of river blockade due to landslide, necessary inputs are provided to Govt. from time to time.
