Nepal landslide hazard mapping project

November 4, 2015

In response to the earthquakes in Nepal this spring, the Yale Himalaya Initiative began a collaboration with the International Centre for Integrated Mountain Development (ICIMOD), a Himalaya focused research organization based in Kathmandu, to produce a landslide hazard map of Nepal. The 7.8 magnitude earthquake caused numerous landslides throughout the impacted region, leading to loss of life, property, and livelihood. ICIMOD had already mapped landslide risk in the earthquake impacted zone but had not done so for the whole of Nepal. YHI’s Hazard Mapping Team created a nationwide map based on the methodology used by ICIMOD for their regional map. The map draws upon seven factors to model landslide risk by combining the geospatial power of GIS with logistic regression. The map, in ICIMOD’s hands, may be shared with policymakers, decision makers, and other interested parties in order to better inform disaster preparedness efforts. YHI is currently in conversation with ICIMOD about how to support ICIMOD’s participatory mapping goals.
