Synthetic ground motions of the 8 October 2005 Kashmir earthquake (Mw 7.6) were generated in the Kashmir basin, NW Himalaya. This earthquake caused paramount amount of damage to life and property. It resulted in death of 86,000 people and destroyed property amounting to millions of dollars. The stochastic finite fault element method with dynamic corner frequency was used to simulate the ground motions of this earthquake throughout the Kashmir basin. The synthetic ground motions were generated at engineering bed rock and later transmitted to the surface using shear wave velocity (Vs30)NEHRP site classification of the alluvium in the basin. The results are in agreement with the damage trajectory of the earthquake and to the estimates of the ground motion from the field investigations. These results are thus useful in carryout the detailed seismic hazard assessment of the Kashmir basin. Especially when destructive earthquakes like 1555 (Mw 7.6) and 1885 (Mw 6.3) have been reported in the historical archives.
