In the aftermath of the 7.8 Gorkha Earthquake that struck Nepal on 25 April 2015, numerous landslides have occurred in the steep mountains and hills throughout the earthquake impacted zone. The attention of a large number of scientists within Nepal and outside Nepal, namely National Aeronautics and Space Administration (NASA), United States Geological Survey (USGS), Chinese Academy of Sciences (CAS) and Utrecht University has been drawn to the potential secondary risks that might arise in the future. These geohazards include landslide‐dammed rivers, future mass movements (landslides/debris lows), glacial lake moraine failures, and avalanches. On the request of the Office of Prime Minister and Council of Minister, Government of Nepal, ICIMOD provided a preliminary report on Geohazards in the aftermath of 25 April 2015 (12 Baisakh 2072) earthquake. The report was based on the analysis done by ICIMOD and the agencies listed above and highlighted six landslides as potentially risky and recommended continued monitoring. Among them was the landslide in Lower Pisang village in Manang District in Gandaki zone which was considered to be at high risk.
