Fig. 11From: High-density surveys conducted to reveal active deformations of the upper forearc slope along the Ryukyu Trench, western Pacific, JapanSchematic illustration of trench-parallel extension caused by active back-arc rifting that stretches the forearc area. For details of the arc extension, see Kubo and Fukuyama (2003). Note the similar stratigraphy of growth strata (colored in the seismic reflection profiles) in the back-arc side and under the upper forearc slopeBack to article page
