Estimation of S-Wave velocity structure in Hachinohe using the observation of microtremor.

Abstract Array measurements of the long-period microtremors were carried out,and it was estimate ed the S-wave velocity structure using SPAC method and inversion technique based on GA. As a results, depth of soil deposit layer at each site, where S-wave velocity is less than 700m/s, were estimated to be from 70 to 220m
