A seismic refraction survey was conducted along a profile from Shonai, Oita Prefecture to Kushima, Miyazaki Prefecture in Kyushu on December 8, 1994. The total length of this Shonai-Kushima Profile was about 195km, and three shots of 500kg each were detonated at both ends and middle of the profile. A total of 195 temporary observation points equipped with analog or digital recorders were arranged on the profile. Recorded seismic signals suffered from high attenuation, and signals traveling more than 100km were very poor. Very clear later arrivals, presumably reflected waves from deeper part of the crust, are recognized in the record sections.
