Paleoseismic investigations so far carried out in India are spread over two tectonically distinct areas, viz., the interplate seismic zone of Himalaya and the intraplate Stable Continental Region (SCR). Most of the reported paleoseismicity studies provided geological evidences like soft sediment deformation, paleoliquefaction features (like sand dykes, sand blows etc), small scale folding, faulting with disptacement of beds etc. Though the evaluation of recurrellce period of destructive seismic events is a pre-requisite for paleoseismology, no paleoseismic study in India so far has provided information on the recurrence period, except for the detailed study in the Shillong plateau, which suggested recurrence period of 400-600 yrs for major earthquakes.Keywords

The hard rock aquifers of southern and western India, receive less than 10% precipitation as natural recharge, and are witnessing Over-Exploitation. Consequently measures are being adopted to augment groundwater resources artificially. Percolation ponds or tanks the most popular artificial recharge structures in India, are constructed across monsoon streams for the above purpose. However no detailed study was carried out to evaluate their performance in different hydrogeological environs. This paper reports the efficacy of percolation ponds, situated in different geological terrains evaluated using chloride mass balance method. Depending on the location of the percolation tanks, varied percolation fractions (of impounded water) were obtained, Basalts 0 20-0 30, Granite-Gneisses 0 30-0 45, and Sandstones 0 60, depending on the transimssion properties of rocks. In addition, soil characteristics and ambient hydrogeological regime of the area are important factors controlling the efficacy of a percolation tank.Keywords
