It is the second largest reservoir in India, which is built on Rihand river in the failed rift region of central India. Most of the earthquakes occurred during the high water stand in the reservoir with a time lag of about 1 month. We use the concept of coulomb stress change and use Green's function based approach to estimate stresses and pore pressure due to the reservoir load. We find that the reservoir increases coulomb stress on the nearby faults of the region that are favourably oriented for failure in predominantly reverse slip manner under the NNE–SSW compression and thus promotes failure. The above two factors make it an obvious, yet so far unreported case of reservoir triggered seismicity. date: 2007-07-20 date_type: published publication: Tectonophysics volume: 439 number: 1-4 publisher: Elsevier pagerange: 171-178 id_number: doi:10.1016/j.tecto.2007.04.003 refereed: TRUE issn: 0040-1951 official_url: http://dx.doi.org/10.1016/j.tecto.2007.04.003 access_IS-EPOS: limited owner: Publisher citation: Gahalaut, Kalpna and Gahalaut, Vineet K. and Pandey, M.R.
