In this study, the effects of implementing stochastic finite fault ground motion simulations in earthquake hazard and risk assessment are evaluated. The investigations conducted for city Dehradun (Indian Himalayas). We compare two estimation techniques: a prediction equation–based technique simulation-based technique. comparison focuses on differences techniques imply damage loss estimates. Ground first calibrated against instrumental recordings 1991 M w 6.8 Uttarkashi earthquake. Afterward, number events considered with different magnitude, distance, azimuth to source. Results indicate large between estimates derived by methods, especially direction rupture propagation, which persist 2–2.5 lengths distance. It is therefore strongly recommended consider kinematics orientation test bed when providing near-field studies.
