The Tokachi Basin, the second largest sedimentary basin on the Japanese islands, is located in the hinterland of the Hidaka Collision zone, Hokkaido. The eastern part of the basin is bounded by the NS trending Tokachi active fault system, which is an east-dipping reverse fault system. In 1999, an extensive seismic reflection survey was undertaken across this basin, from which inportant information on the shallow part of the basin structure was obtained. This paper presents the seismological structure from the refraction analysis with its preliminary geological interpretation.
