| | Abstract | | The measurements of microtremors were conducted in the Tsuruga plane, Japan. We calculated the horizontal-to-vertical spectral ratio of microtremors. We applied a grid search method of horizontal-to-vertical spectra of surface wave for estimating of a 1D S-wave velocity structure. The inverted structures of sediments are in good agreement with the results of previous research and S-wave velocities calculated from N-value. |
