Subducted structures parallel to the trench. The southern portion of seismic strike line S13 (Figure 1). Red region shows chaotic reflectors and accreted sediments. Blue region contains more continuous reflectors and appears less deformed. The boundary between red and blue is the décollement (black dashed line). Green region is the upper part of the igneous crust offset by basement-cutting normal faults (red lines). Solid black lines show intersections of seismic dip lines (Figure 1).
