The 2015 Gorkha, Nepal, Earthquake and Himalayan Studies: First Results

Edited by: Hiroe Miyake, Soma Nath Sapkota, Bishal Nath Upreti, Laurent Bollinger, Tomokazu Kobayashi, Hiroshi Takenaka

A devastating earthquake with a moment magnitude of 7.9 struck Nepal on 25 April 2015, resulting in more than 8,000 fatalities. This earthquake has a remarkable seismological feature in that the interplate earthquake occurred just below the inland area, which can offer an invaluable opportunity to deepen our understanding of earthquakes in the collision zone and related disasters. This special issue focuses on multidisciplinary geoscientific research regarding the 2015 Gorkha, Nepal, earthquake and the relevant tectonics along the Indian-Eurasian plate collision zone.
