    Earthquake Hazard in the Tehran Region based on the Characteristic Earthquake Model

    Tehran is the most vulnerable urban area in Iran. Here, the characteristic earthquake model for the major earthquakes was integrated with the background seismicity to conduct the PSHA. For a 2475-year return period earthquake, a maximum PGA of 725 cm/s2 and a maximum PGV of 60 cm/s were estimated. In next step, the simulated ground motions of the North Tehran Fault (NTF) were applied directly into the PSHA. Due to the fault rupture directivity effect considered through the simulations, the maximum PGA and PGV were estimated 845 cm/s2 and 100 cm/s respectively for a 2475 year return period. If we change location of hypocenter in our simulations, the distribution of highest hazard region will also change.
