 The geotectonic information on North India region has been processed using GIS (Geographic Information Systems), GeoProcessor for extracting the spatial seismotectonic properties. According to spatial modeling of the principle seismotectonic parameters the region under study can be divided into four zones as Kangra-Chamba, Garhwal-Kumaon, Punjab reentrant and Delhi-Haridwar. The b-value is low (0.5) for the Kangra-Chamba and Garhwal-Kumaon region, which shows that the regions have less capacity to withstand the developing stress. The elliptical region between Main Central thrust (MCT) and Main Boundary Thrust (MBT) are sensitive to the tidal force.
