In the terrace area with a steep basement inclination, geophysical exploration methods on the basis of one-dimensional horizontally stratified model using microtremor phase velocity might have brought undesirable results. As the reason of the experimental results, it could be interpreted that microtremor array measurements are likely to be less ‘robust’ than microtremor H/V spectra measurements in a long period range. Therefore, the highly-accurate inversion analysis using microtremor H/V spectra was proposed as a tool for the modeling of the shape of basin-bedrock interface of basin structure based on numerical experiments.
