Abstract:Most the major earthquakes occur in subduction zones. However, there are few studies on earthquakeinduced landslides in subduction zones. On Apr. 25, 2015, an earthquake (Mw=7.8) hit Gorkha district, Nepal,which was the first strong earthquake in the Himalayan subduction zone in nearly 70 years. Focal mechanism solution shows that it is a lowangle thrusting subduction zone earthquake and induced a large number of secondary disasters such as landslides and collapses. 2072 sets of seismic landslide information were obtained by remote sensing interpretation and field investigation. Seismic landslides are mainly distributed between 1000 and 3000 m above sea level, in the transitional areas of the Higher Himalayas and the Lower Himalayas, spreading and distributing along the MCT, with large slopes in terrain. Paleozoic sedimentary rocks which are transformed from the mediumand highgrade metamorphic rocks, combine a small amount of magmatic rocks to form thrust sheets, and therefore the rock strata are liable to trigger geological?disasters such as landslides and collapses. The predominance range of slope values of the landslides in this earthquake is between 35°~40°, which is the same as the western region of China. The aspect values prominent distribution is between 120°~200°. In the light of the comprehensive GPS deformation field data, it reveals that the landslide aspect is closely related to the horizontal deformation field. Taking Nepal earthquake landslide as an example, the characteristics of earthquake landslide in subduction zone are discussed.The landslide points are apparently planar distribution and closely related to the deep low dip fault rupture plane. Earthquaketriggered landslides in the subduction zone are affected by the inertia effect of the plate movement. It is more likely to trigger seismic landslides on the slope which is in the same direction as the thrust direction on the hanging wall side.
