Trench axis bathymetry. The dashed black line marks the deformation front based on seismic and bathymetric interpretations. White and black circles mark the deformation front located above a graben or horst, respectively, whereas a gray dot marks a half-graben. Seismic line numbers (e.g., D02, D03) are plotted near respective circles. Blue box marks location of inlet to the right. White and black solid lines are normal faults dipping seaward and landward, respectively. The trench axis is marked by a red dashed line. The green lines are the location of the seismic lines. The white dashed line is an anticline. The deformation front is not merely following topographic lows but may be reacting to the incoming structures.
