The rainfall-induced landslides in the Nepal Himalaya extend tremendous damage to lives, property, infrastructure, and environment, particularly in the monsoon season. This paper particularly discusses the issues related to the rainfall-induced landslides in the Nepal Himalaya. All geological zones of Nepal were evaluated from the landslide occurrence perspective. To evaluate the landslide processes and associated hazards in Nepal, the rainfall-induced landslides were assessed from three perspectives: hydrological and slope stability modelling, rainfall threshold of landslides, and landslide hazard. This paper is an outcome of these evaluations and exclusively covers the major issues of rainfall-induced landslides in the Nepal Himalaya.
