چکیده مقاله
The consequences of recent earthquakes show the importance of site conditions This means that, as well as source and path effects, the recorded data on the ground surface may be affected by site conditions In general, the overall site effect is the site and crustal amplification functions combined with the nearsurfaceattenuation Site amplification is estimated by the H/V ratio Diminishing of the amplitude in the high frequency band may be modeled in terms of the Kappa factor In this study, two datasets areconsidered for determining the H/V ratio and the Kappa factor Using the best available information, recording sites are classified into two main geologic categories: rock VS30>500m/s and soil VS30
