     abstract = "{Reservoir triggered seismicity (RTS) have been documented at about 700
        locations worldwide, with the Koyna-Warna region in Western
        India hosted the largest triggered earthquake of magnitude 6.3.
        Despite substantial work has been done to understand the genesis
        of triggered earthquakes around Koyna-Warna reservoirs, most of
        the research has been limited to the immediate areas of the
        reservoirs. In this study, we expand the investigation to
        encompass a broader area, aiming to explore the impact of
        geological heterogeneity and groundwater storage anomalies
        derived from GRACE satellite data on earthquake occurrence in
        the region. Utilising 30-m resolution digital elevation model,
        we extracted lineaments and generated lineament density and
        trend maps. Analysis reveals a total of 927 lineaments spanning
        33.73 km, with shorter lineaments comprising 70\% of the total
        count. Lineament density ranges from 0 to 1.8 km/km$^{2}$,
        indicating varying degrees of rock fracturing, with densities of
        0.6-1.20 km/km$^{2}$ and 0.4-0.6 km/km$^{2}$ indicate high and
        moderate levels. Dominant lineament trends are observed in the
        N-S, NNW-SSE and WNW-ESE directions. Good correlation between
        lineament density, and earthquake occurrence is observed which
        is further validated from groundwater anomaly.}",
