The RCFs from lines from A–A′ to E–E′ (Fig. 1). a Each box corresponds to a single OBS, in which the observed RCFs (2–6 Hz) are aligned in the order of BAZ from left to right. Pos1 and Pos2 correspond to Pos waves converted at the top of the basement and oceanic Moho, respectively. Gray-shaded area indicates the bathymetry along line A–A′. Yellow star indicates location where Pos waves tend to be weak toward the trench, also shown in a geographical map (Fig. 1). Orange circle corresponds roughly to the ridge point in the outer-rise region, shown in a geographical map with orange dash line (Fig. 1). b–e The same as Fig. 8a, but for lines B–B′, C–C′, D–D′, and E–E′, respectively
