     abstract = "{The Gravity Recovery and Climate Experiment (GRACE) measurements of the
        time-variable gravity field and mass change have helped identify
        regions of water reservoirs over land, ice and ocean, as well as
        in locating areas affected by drought and groundwater over-
        extraction. Studies indicate depletion in groundwater resources
        in North West (NW) India in the past 20 years due to over-
        extraction from agricultural activities. The Global Positioning
        System (GPS) measurements in the region show the signature of
        crustal deformation caused by groundwater depletion-induced mass
        change. Here, we report the vertical deformation from four
        continuous GPS sites within NW India, which show uplift rates of
        1.5─4.2 {\ensuremath{\pm}} 0.7 mm/year. We observed a
        significant correspondence between the rainfall pattern, mass
        change derived from GRACE measurements, GPS measurements-derived
        deformation and well-level changes. Despite some marginal
        increase in rainfall in the past 3─4 years, the region is still
        experiencing over-extraction of groundwater due to increased
        demand. Although the tectonic regime of the Delhi Aravalli fold
        belt paleo-structure mainly controls the earthquakes in and
        around the Delhi region, their occurrence appears to be
        influenced by groundwater over-extraction, as the uplift in the
        region implies unclamping of the faults, which promotes failure.}",
