Single Station Ambient Noise Observations in Tehran

In this study first, we checked particle motion behavior of ambient noise recordings in Tehran. The results show the predominance of Rayleigh waves in ambient noise wave field. Then, we investigated H/V curves of ambient noise recordings. After modeling ellipticity curves of Rayleigh waves, we investigate coincidence of H/V ratio peak with the peak related to fundamental mode of Rayleigh waves. To sum up, in the desired area fundamental mode of Rayleigh wave accounts for the peak observed on the H/V curves, related to site resonance frequency.
