Dear Members: Wish to give you a phenomenon associated with two types of study of Science. One is hydo geology dealing with ground with water resources and other bio- assets on terrestrial surface. 2nd one is seiesmology which deals with study of earth quakes and tremors and their effects. Wish to introduce "the sponge effect"  in sub- soil strata with greens and water resource on ground and under ground in aquifers. When there is water resource in aquifers and land surface, with greens this layer of soil behaves like "a sponge" in absorbing the shocks and tremors in the times of earth quakes and prevents it being conveyed upper to surface zones.  It is propable in dense urbans, these areas are heavily populated with high-rise buildings too. One shudders to consider the repurcusions when shocks and tremors if left un absorbed and  are transmitted to surface regions. When aquifer is contained with ample water then we consider that the soil is moist, soft and spongy. The corollary occurs when water is deficient and water has gone to levels very deep in aquifers, soil has no moisture, ie hard or very hard like rocks.  This sponge present in sub -soil, therefore is more than beneficial for neo - urbans, as it absorbs seismic shocks. The sub - strata sponge also absorbs the flow of water as it flows through the water-shed, thus keeping water stored in their aquifers. Therefore the WR, is required as mandatory requiremnt for good quality of urban- living.  Pl consider the point as given and take safe guard on the same. Well wishes. Prof Ajit  Seshadri. INDIA.
