چکیده

This study carried out the probabilistic seismic hazard analysis of Iran, using updated earthquake catalog and special attenuation relations considering Iran's major seismic zones, which were developed by the authors with the last earthquake catalog of Iran. The PGA, PGV and spectral acceleration with 5 % damping can evaluate by attenuation relation considering seismic zone and site condition. All the earthquake events until 2010 happened in and near Iran were considered for probabilistic hazard analysis. In this study seismic hazard was evaluated in terms of 10% and 2% exceedance probabilities of occurrence in 50 years. Results of this analysis using probabilistic approach were put in a GIS-based system to be able to show visually site specific design spectra for each part of Iran. We made a mesh net by 0.1*0.1 degree in geographic longitude and latitude. GIS-based seismic hazard assessment system can predict PGA, PGV and acceleration spectrum for any mesh of Iran. The seismic hazard we evaluated can show the high probability along the active fault. Outcomes of this study would contribute for the quick and better estimation of the seismic hazard applicable to the seismic design of structures.

اطلاعات بیشتر در مورد COI

COI مخفف عبارت CIVILICA Object Identifier به معنی شناسه سیویلیکا برای اسناد است. COI کدی است که مطابق محل انتشار، به مقالات کنفرانسها و ژورنالهای داخل کشور به هنگام نمایه سازی بر روی پایگاه استنادی سیویلیکا اختصاص می یابد.

کد COI به مفهوم کد ملی اسناد نمایه شده در سیویلیکا است و کدی یکتا و ثابت است و به همین دلیل همواره قابلیت استناد و پیگیری دارد.
