ESTIMATION OF SEISMIC HAZARD MAP USING PSHA TECHNIQUE

Abstract

The work displayed in this paper indicates the probabilistic seismic peril guide of the Uttarakhand l-limalayas. Probabilistic Seismic hazard estimation from the given areas is peak ground acceleration are computed at cvciy perception point by the assistance of displaying of peaks along every lineament with the utilizing of semi empirical technique .The seismotectonically paramount area of Uttarakhand Himalaya has been considered in my work. Ruptures along the lineamenis in the zone is recognized from tectonic map are demonstrated - probabilistically utilizing semiempirical technique. This methodology makes utilization of lessening connection of peak ground acceleration for reenacting solid ground movement information at any site. The created attenuation is utilized as a part of the semi empiricalapproach to anticipate peak ground acceleration from the demonstrated rupture planes in the region. A set of estimations of peak ground acceleration from conceivable exceedence in the zone at the purpose of examination is further used to register likelihood of exceedence of peak ground acceleration ofvalueslOO gals and 200 gals at 10 % probability of exceedence .Peak ground acceleration of 250 gals at 5 % probability of exceedence
