Along-trench distribution of the dip direction and throw magnitude of the normal faults. a Average number of normal faults along a 30 km-long seismic line. The average number of the faults with eastward or westward dips along the seismic lines was estimated over every 0.5° of latitude. b The average cumulative throw along a 30 km-long seismic line. The average cumulative throw of eastward or westward dipping faults along the seismic lines was estimated over every 0.5° of latitude. c Average throw of a single fault. The average throw of eastward or westward dipping faults was estimated over every 0.5° of latitude. In all cases, normal faults with a vertical throw of > 50 ms were counted. Red and blue bars indicate eastward and westward dipping normal faults, respectively. Gray lines with arrowheads indicate the three segments inferred in this study. “s-segment,” “c-segment,” and “n-segment” denotes southern, central, and northern segment, respectively
