This study presents the results of seismic hazard mapping and
ground motion assessment for central Alborz region in Iran. The results have been based on historical seismicity, recurrence statistics and probabilistic ground motion analysis. The seismicity parameters were calculated by Weichert Maximum Likelihood Method. Seismic
hazard was assessed as maps for 10% and 64% probability of exceedance in 50 years. The estimated values for peak ground
acceleration were 0.53g and 0.19g for the above probability levels respectively in the region 48.5E to 54.5E and 34.5N to 37.5N.
Because of low amount of data and uncertainty of location, time and magnitude of the historical events, estimated value also contains uncertainty. The results of this study show importance of estimating slip rate of faults for more accurate studies in the future
