Abstract
S wave velocity structure plays key roll to estimate seismic around motion. However, we do not have in situ S wave velocity data around Hachinohe city. ln this study, we carry out microtremors exploration around Hachinohe city hall. While we estimate the S wave velocity structure using empirical relation for S wave velocity to SPT N-value and soil type from compiled soil profile. We calculate dispersion curve from the model and compare to 0bserved one. In this case, empirical relation works well within almost 10 % velocity change. We think that we show one example of applicability to estimate the site effect using empirical relation for S wave velocity.
