Overview:

ISRO Workshop "Earth Observation Based Mapping, Monitoring, and Modelling of Landslide: Recent trends and support to early warning system".

Landslides are a frequently occurring natural as well as a man-made hazard in the mountainous terrains owing to a wide variety of causative as well as triggering factors like heavy rainstorms, cloudbursts, earthquakes, geo-engineering setting and anthropogenic activities.
In the Himalayan and Sahadri mountainous region, landslides are mostly rainfall triggered and although they are individually small in dimension but occur with a high frequency and cause substantial damage to life and property
Thus the national imperative towards safety due to landslide initiation is increasing in view of the higher rate of human settlement in the mountain slope across the country
Hence, the current techniques include landslide classification, detection, digital elevation model reconstruction, surface deformation monitoring, and volume/mechanism inversion. In addition, landslide susceptibility mapping, hazard assessment, and risk evaluation can be further analyzed using a synergic fusion of multiple remote sensing data and other observations affecting landslides
