This book describes the source parameters, faulting mechanism, slip distribution, rupture pattern, and aftershock behaviour of the Nepal Earthquake of 2015. This book sheds light on the damage pattern and the geodetic deformation and past seismicity and geology of the region. It also discusses empirical relations useful for assessing future earthquakes and the possible extent of damages caused by the different intensities, magnitude, and duration of aftershocks. Arguments discussed in the book are applicable not only to the Himalayan region but also for similar geological settings worldwide, helping improve disaster management and mitigation planning. This book is of interest to students, researchers, administrators, and planners engaged in earthquake risk reduction. .
