Effect of Seismotectonic And Engineering-Geology on Seismic Danger of Territories In India

Seismic hazard map seen in territory and adjacent areas has been prepared employing a deterministic supported the computation of synthetic seismograms. Data set consists of structural models, seismogenic zones, focal mechanisms and earthquake catalogues, using realistic strong ground motion modelling with the knowledge of the physical process of earthquake generation, the extent of seismicity and wave propagation in anelastic media. Prehistoric on earthquakes are often obtained through the utilization of palaeoseismic techniques. the prevailing procedures for assessing different natural hazards are essentially similar. the primary step is usually the definition of the source model in terms of the source location and therefore the frequency and size of probably damaging events; the second step relates to the propagation of disturbances from the source; and the third step, involves the event of an exposure model for a site or for a neighborhood. it's obvious that accuracy of assessment depends on the number and quality of input file. There are too many samples of an uncritical use of published data for hazard mapping, all of which illustrate the necessity for a careful revision and unification of the input information. Processing heterogeneous data leads only to misleading result.
