Satellite derived information and ancillary data have been used for demarcating the landslide susceptibility zones along the pilgrimage and tourist routes in Uttarakhand, Himachal Pradesh and North Eastern Region. Using WRF based forecast rainfall and statistical relationship derived between landslide initiation & antecedent, as well as daily rainfall values, an experimental early warning system has been developed for rainfall induced landslides. Semi automated landslide mapping is being carried out seasonally and also after major triggering events.

 The area in and around Kedarnath, Uttarakhand, witnessed a large scale occurrence of flood and landslides between the 16th and 17th of June, 2013 due to incessant rainfalls upstream of Mandakini river and its tributaries. A landslide inventory is being carried out for the affected area using pre and post IRS data.

A total of 2395 landslides have been identified along the river valleys of Mandakini, Basuki Ganga, Mandani, Kali, Madhyamaheshwar, Bhillangana, parts of Alaknanda (including upper Saraswati valley) and its tributaries like Kalpa Ganga, Kalapani Gad, Khirao Ganga and Rishi Ganga from Srinagar to Chamoli (also around Jakhpur, Kalpeshwar, Khiraogarh and Mana) and parts of Bhagirathi around Gangotri. The major towns included in this area are Kedarnath, Sonprayag, Gaurikund, Okhimath, Guptkashi, Mansuna, Phata, Agastmuni, Rudraprayag, Srinagar, Gauchar, Karnaprayag, Nandprayag, Chamoli, Jakhpur, Kalpeshwar, Khiraogarh, Mana, Gangotri, etc.
