Seismic interferometry analysis of short-period microtremor observed with a linear array for estimating two-dimensional shallow S-wave velocity structures - An experiment in a ground of Iwate University -

Abstract Microtremors were observed in a linear array with the length of 100 m and with a seismometer interval of 10 m in the ground of Faculty of Science and Engineering, Iwate University, and the Green functions were calculated from stacked three components cross correlation functions. Group velocities were calculated by multiple filter analysis. As a result, obtained group velocities were in good agreement with calculated ones.
