| | Abstract | | We conducted P-wave high-resolution shallow seismic reflection survey near the point of Miho peninsula, Shizuoka City, to obtain subsurface structure between 100m and 300m deep. E-W and N-S survey lines were set orthogonally along paved road, unpaved road and baseball sub-ground. They are approximately 600m and 400m long, respectively. The preliminary CMP stacked sections show several continuous reflectors between 60m and 400m in depth. Reflector of 60m in depth is correlated to the boundary depth detected by nearby boring cores. Below 60m, reflectors dip southward with apparent 4 to 13 degree. Dips of shallow reflectors are larger than those of deep reflectors. Onlap structure is perceived between 100m and 200m in depth. |
