Abstract

Iso-acceleration and seismic hazard maps of Iran were prepared based on the results of deterministic and probabilistic evaluation of the ground shaking hazard. The seismic source model used in this analysis was based on the results of seismotectonic and seismological studies to identify active faults and seismic source zones and to characterize them in terms of location, maximum earthquake magnitude, and earthquake recurrence. Taking into account probable ground motion attenuation effects, isoacceleration contours of peak ground acceleration were computed for three return periods (500, 1000, and 2000 years). Finally, 1:1,000,000 scale seismic zonation map was prepared for the country. The maps are based on average site conditions.
