A seismic refraction survey was conducted along a profile from Fujihashi, Gifu Prefecture, to Kamigori, Hyogo Prefecture, on November 9, 1989. The total length of the Fujihashi-Kamigori Profile was about 220 km, and four shot points and 137 temporary observation sites were arranged along it. Charge sizes of the shots were 800 kg and 500 kg. Recorded signals were of good quality, except those of distant sites for a shot in Kamigori due to unexpectedly bad weather conditions. Travel times of first arrival with an apparent velocity of about 6 km/s were rather smooth, and very clear reflected waves from the deeper part of the crust or the upper mantle were recognized on the record sections. Analysis of the high-quality data set might reveal a fine image of the crust in this area from the shallower part to the deeper part.
