Fig. 5From: Seismic structure of rifting in the Okinawa Trough, an active backarc basin of the Ryukyu (Nansei-Shoto) island arc–trench systemP wave velocity models for the survey lines perpendicular to the trough axes. The contour interval is 0.25 km/s. These Vp models were arranged from north to south and along the slope between the ECS shelf and the OT. The vertical dashed blue line shows the position of the northwestern edge of the OT. Upward arrows on ECr8 and ECr9 indicate ascending high Vp materials in the top sedimentary layers.
