Background and Purpose: In this research, seismic hazard maps of district 8, region 1 of Tehran Municipality with central coordinates of 51.459839 (longitude) and 35.793794 (latitude) has been estimated and analyzed.
Method: This research is a sort of practical study using analytical estimation. In fact, the main issue of this work is to evaluate and find a relationship between what is current status and what should be the status using a case study. As a first step, data collections based on the existing evidence and documents gas been done and then, as the second step using literature review and documents and analyzing the obtained data, the results were determined.
Results: The seismic catalog of the study area (within a radius of 150 km from the center of the study site) was collected according to the seismic data bases. Consequently,  seism genetic sources were determined using the map of active faults in Iran and the history of the occurred earthquakes. In the follow, using Zmap software, seismic parameters of the region and seismic sources (B-value and Rate) were determined.
Conclusion: The modeling of the study area in EZ-FRISK application software showed that according to the obtained results, the maximum of  peak ground acceleration (without considering any factors of safety) in this area for a return period of 475, 975 and 2475 years was respectively predicted as 0.38g, 0.51g and 0.71g.
 
Keywords: Peak ground acceleration, Probabilistic seismic hazard assessment, Tehran municipality
