Fig. 6From: High-density surveys conducted to reveal active deformations of the upper forearc slope along the Ryukyu Trench, western Pacific, JapanStacked seismic profile of the upper forearc slope (see Fig. 2 for the track location). The thick area of seismic unit B covering the acoustic basement has a thickness of 2.0 s (TWT). Seismic unit D, which is stratified, unconformably covers seismic Unit B on the island shelfBack to article page
