Fig. 10From: Seismic structure of rifting in the Okinawa Trough, an active backarc basin of the Ryukyu (Nansei-Shoto) island arc–trench systemExample of forward modeling for ECr5. a Observed record section of OBS038. Red arrows and blue arrows indicate PmP signals and refraction waves propagating through the Yaeyama Knoll, respectively. The position of the OBS038 is indicated by a red inverse triangle in Fig. 2. b Synthetic seismograms. c Calculated travel times on the synthetic seismograms. d Ray diagram. The ray paths are generated at equal distanceBack to article page
