We conducted seismic surveys in western Kanagawa prefecture including the Kozu-Matsuda fault zone and Ashigara valley, in February and March 2002. The reflection surveys were carried out using vibrator sources along 2 receiver lines. Line A is 15-km long and extends east to west across the Kozu-Matsuda fault zone and Ashigara valley. Line B is 10-km long and extends north to south in the valley. 1151 receivers were deployed at intervals of 25m for 210 vibration points. 3-D refraction surveys were also conducted with 4-dynamite shots at both sides of the lines A and B and repeated vibroseis sweeps were made at 3 points. In addition to the 1151 reflection receivers, 108 receivers were deployed along the 5 lines between the shot points, and 128 independent receivers were located over a wide area in the Ashigara valley. We overview the surveys and present datasets of seismograms and travel times.
