The Application of the H/V Spectral Ratio Technique for Estimating the Site Characterization in the South of Iran
Publication: Soil Dynamics and Earthquake Engineering
Abstract
As microzonatin studies, microtremor measurements were carried out in many cities in Iran and the resonant frequency of each station was estimated from the peak at the spectral ratio between the horizontal and vertical component. For many of these stations the thickness of the sedimentary cover was known by conducting boreholes or geophysical investigations, and a clear correlation between the resonance frequency and sediment thickness was observed. Three of these cities are located in the southern part of Iran near the sea (Persian Gulf). We attempted to derive a formula to correlate the frequency of the H/V peaks to the soil profiles properties such as thickness, materials properties and shear wave velocity. In addition, by using all of these microtremor measurements and applying the derived relationship, we tried to estimate the basin shape for these areas.
