000018813 520__ $$2eng$$aStochastic simulation of strong ground motion is commonly based on Brune’s far-field spectrum with point source assumption. The effect of finite fault rupture is considered either by discretizing the large rupture area into smaller subfaults, with each subfault assumed to be a stochastic point source, or by using an equivalent source to site distance. Thus near field effects are not accounted in the currently used stochastic simulation via seismological source model approach. This paper proposes to use weighted combination of Brune’s near field and far-field source spectra in the stochastic simulation method. The application of the proposed simulation method to Mw 6.8 Uttarkashi earthquake of October 20th,1991 and Mw 6.5 Chamoli earthquake of March 28th,1999 in Western Himalayan Region has shown considerably improved results compared to the commonly used point source far field approximation.
