Landslide is a rapid movement of rocks, soils and vegetations down the slope under the influence of gravity. Landslides are by far the most common natural disaster and pervasive natural problems in the Himalayan region of Darjeeling. Every year, people have to face this natural vengeance without any effective preventive measures and management system thus leading to huge loss of life and property. Darjeeling district with a geographical area of 3,149 sq km lying within the Lesser and Sub - Himalayan belts of Eastern Himalayas is one of the most vulnerable regions for the landslides and over the year frequency has greatly increased. Within Darjeeling, notably Pagla Jhora region is one of the worst affected, where such landslides occurs with the onset of monsoon cutting off National Highway 55 which connects the Himalayan region with rest of the state of West Bengal. Over the decade various preventive measures has been taken up but yet the result has not been achieved. As such, an in depth study and analysis is required regarding its causes and possible measures to stabilize it.
