Example of forward modeling for ECr6. From top to bottom, observed record sections, synthetic seismograms, and travel time fitting with ray diagrams for OBS040 (left) and OBS053 (right), respectively. The colors of the calculated travel times on the record sections correspond to the ray paths in the ray diagrams. The ray paths are generated at equal distance. The positions of the OBS040 and OBS053 are indicated by blue inverse triangles in Fig. 2. DM Daiichi–Miyako Knoll, MS Miyako Seamount
