Seismic Disaster Characteristics of Building of Nepal M8.1 Earthquake on April 25, 2015

Numerous buildings and facilities in Shigatse, southwest of Tibet, were hit by the Nepal M8.1 earthquake on April 25, 2015, with an epicenter intensity of IX degree. The civil structures and stone-wood structure houses are damaged more seriously than masonry structures and frame structure buildings. The damage along the Brahmaputra river is greater than in other districts, because of the deep Quaternary overburden. Seismic geological disasters, such as landslide and rockfall, caused heavier casualties and property losses than the ground motion itself.
