Estimation of deep ground S-wave velocity structure using the horizontal array earthquake records


Abstract
An array measurement of earthquakes are conducted in the Wakasa bay area, for estimation deep groud S-wave velocity structure. Array consists of 5 long period seismometers with a station spacing of 2km to 5km. Phase velocities of Rayleigh waves are estimated from semblance analysis. And we estmate the deep ground S-wave velocity structure form surface to about 5km depth.
