Indeed, seismic energy is accumulated in front of the propagating rupture and is expressed in the forward directivity region as a large velocity pulse. Tabriz is capital of Azerbaijan province and one of the ancient cities in North-West of Iran. This city is surrounded by several active faults which caused many destructive earthquakes in history of Iran. One of the most active faults is in northern part of the city and is in close distance from urban area. Due to presence of several heavy industrial factories, financial centers and historical monuments, seismic hazard analysis of area with considering near field effect, is a national and regional project. This study tries to generate uniform hazard spectrum of Tabriz zone caused considering active faults in vicinity of Tabriz. This paper compares generated seismic spectra for near field with conventional seismic spectra for far field in Tabriz zone. The difference of two spectra reveals the long-period pulses in near fault records are important factor in causing damage of structures.
