An extensive onshore-offshore seismic refraction/wide-angle reflection experiment was undertaken in 2001. The profile line was extended from the eastern part of the Nankai trough to Central Japan. The land profile line of 261-km length was laid from the Tokai district to the coastal region of the Sea of Japan, crossing an expected fault area of the forthcoming Tokai earthquake, an aseismic slip region north of the fault area, the Median Tectonic Line and the Niigata-Kobe Tectonic line. On this profile, 391 receivers were deployed to observe 6 dynamite shots with 100-500kg charge. Data obtained are of good quality, from which clear first arrivals are traced beyond 120-160km offsets. The most important feature in these data is strong ref...
