Summary

The 25 April 2015 Mw 7.8 Gorkha earthquake and its aftershocks triggered about 25,000 landslides over an area of more than 30,000 km2 in the Greater and Lesser Himalaya of Nepal and China. In order to understand the relation among landslide location, earthquake shaking, topography, tectonic geologic and climatic setting, earthquake-triggered landslides were mapped using high-resolution (<1m pixel resolution) pre- and post-event satellite imagery. Source and runout areas were differentiated and mapped separately. The data accompany an interpretive paper published in the journal Geomorphology. The published products are separate ESRI ArcMap 10.2.2 shapefiles that comprise: (i) mapped landslide source areas, (ii) mapped landslide full [...]

Purpose

The data were collected to document the extent and severity of landslides triggered by the 25 April Mw7.8 Gorkha earthquake and aftershocks in Nepal. Appropriate use of the data include verification of landslide susceptibility models, baseline information informing post-earthquake geomorphic studies, among others.
