ABSTRACTThe research has been conducted to investigate the seismicity and seismic hazard zoning in Rasht city, the tomb of Mīrzā Kūchak Khān. The purpose of such studies is to ensure existing structures and to estimate acceleration for future structures. The studies of this project are based on the collection of catalog of the historical and instrumental earthquakes in radius of ۱۵۰ km of the given structure. By investigating the seismogenic sources and active faults in the study area, their information was obtained and, via EZ-FRISK software, the hazard analysis of the given structure was analyzed by the Probabilistic Seismic-Hazard Analysis method (PSHA) and using three attenuation relations, (Campbell & Bozorgnia. ۲۰۰۸) [۱], (Abrahamson & Silva. ۲۰۰۸)[۲], (Boore & Atkinson. ۲۰۰۸)[۳], and seismic acceleration for three recurrence intervals of ۴۷۵, ۹۷۵, and ۲۴۷۵ of area was estimated.
