In 1998, a seismic reflection experiment was conducted in the northern part of the Hidaka collision zone, Hokkaido, Japan. The aim of this experiment was to investigate the style of crustal deformation associated with the collision of the Kuril Forearc against the Northern Honshu Arc, which has lasted since the late Miocene. Two profiles with 21- and 10-km lengths were shot using both vibroseis and dynamite sources. In addition, we deployed 44 offline recorders to map the deeper part of the crust. These data are also used to constrain the crustal velocities from a seismic refraction approach. This paper outlines the experiment with some representative seismic wave data obtained.
