Abstract

Summary

In order to derive 1D Vs profile, inversions have been done only on specific part of microtremor H/V curve. This part which is between first peak and first trough, here called as Rayleigh wave energy rich of H/V curve. Inversions were done based on the neighborhood algorithm. Some available data of site such as downhole seismic, geotechnical information, surface geology and soil texture, were used for building a robust model parameter. 1D extracted velocity profiles show good agreement with traditional geophysics and inversion of the ellipticity curve results.
