Attempt of estimation of phase velocity by microtremor records using an array with reference point in Wakasa Bay area


Abstract
A seismic interferometric processing was carried out using simultaneous observation data of microtremors at Hi-net observation stations and strong motion observation stations in the Wakasa bay area. In a seismic interferometric processing, Hi-net observation data was used as reference data. The Phase velocity of Rayleigh waves was estimated from semblance analysis using cross correration waves. The estimated phase velocity was consistent with that of estimated by Oba et al.(2010).
