Seismic Interferometry Analysis on microtremors records observed by a linear array with broadband seismometers in Fukushima Prefecture, Part 1

Abstract Microtrermors were observed with a linear array which consists of 10 broadband seismometers in Fikushima Prefecture. Group velocities were calculated from stacking cross correlation functions of microtremors by multiple filter analysis. Two-dimensional distribution of group velocities were obtained by averaging the group velocities along the array observation line.
