Seismic depth profile (above) and semilogarithmic heat flow plot (below) for the six survey lines in this study. (a) Line KIN_030. (b) Line KIN_038. (c) Line KIN_046. (d) Line KIN_54. (e) Line KIN_062. (f) Line KIN_070. Blue dashed rectangles on (f) correspond to the regions shown in Figs. 5 and 8. The Imbricate Thrust Zone (ITZ) was formed in the middle of the accretionary prisms. The plutonic rock (PR) inferred by Kimura et al. 2022 may be underlain in (e) and (f). Yellow arrowheads denote the BSRs. Red arrows indicate high heat flow anomalies associated with eroded seafloor
