     abstract = "{Groundwater usage in the Indo-Gangetic plains exceeds replenishment of
        aquifers, leading to substantial reduction in the mass. Such
        anthropogenic crustal unloading may promote long-term fault slip
        or may modulate seismic activity in the adjoining Himalayan
        region. Our simulation using Gravity Recovery and Climate
        Experiment data and hydrological models of such a process
        indicates that the thrust earthquakes on the Main Himalayan
        Thrust (MHT), including the recent 25 April 2015 Mw 7.8 Gorkha,
        Nepal earthquake, are probably influenced by the anthropogenic
        groundwater unloading process in the Gangetic plains. The
        groundwater withdrawal leading to crustal unloading in the
        Gangetic plains causes a significant component of horizontal
        compression which adds to the secular interseimic compression at
        the seismogenic depth (5-20 km) on the MHT beneath the Himalayan
        arc and at hypocentral depth of the 2015 Gorkha, Nepal
        earthquake. This effect enhances the Coulomb stress on the
        locked zone of MHT.}",
