Purpose – The aim of this paper is to present a discussion on prognosis and mitigation of major landslide zones in an attempt to minimize the impact of such disasters in future. A case study on the sequence of sliding events of Varunavat Parvat, Uttarkashi (India), response of masses and administration and causative factors of sliding events has been presented in detail for prognosis and mitigation of large slide zones.
Design/methodology/approach – The prognosis and mitigation strategy discussed is based on the monitoring of mass wasting zones through field investigations and satellite image analysis (of pre- and post-landslide period images) and experiential learning and interaction with village elders in landslide hazard-prone Himalayan terrain.
Findings – The paper finds that Himalayan habitations such as Uttarkashi (which is situated in an area of fragile rocks, complex tectonics, seismic activity and cloud burst-prone unstable hill slopes with colluvium and old slide zones) should have minimum anthropogenic activity in the form of slope cutting for road or building construction.
Research limitations/implications – The paper reflects the author's individual understanding of causative factors and indications of landslides in Varunavat Parvat area in Uttarkashi township of Uttarakhand (India).
Originality/value – The paper calls for amalgamation of experience-based local knowledge of villagers of landslide-prone areas and modern scientific and technical know-how and above all the coordinated efforts of community and authorities for prognosis and mitigation of large-scale landslides in the inhabited areas. It has been further emphasized that sensitization and awareness programs and strict implementation of land-use regulations are vital components of effective mitigation strategy.
