Preparations for future great earthquakes seen in levelling observations along two lines across the outer Himalaya

Abstract

An important set of levelling observations across Central Nepal have been reported in the literature recently. We infer from these observations that recoverable elastic strains are accumulating in the upper crust of the region and will lead to a great earthquake in course of time. Limited levelling data from the Dehradun region in northwestern Himalaya show remarkable similarities to the Nepalese data and require a similar interpretation regarding preparation for the next great earthquake in the region.
