Synthetic seismogram for the record section of SP1 (Fig. 3a). The red line indicates the picked traveltime in Fig. 3a. a The synthetic data of the model with a LVZ of 5.7 km/s at about depth 10 km. b The synthetic data of the model without the LVZ. These two seismograms indicate that the model without LVZ cannot generate the strong reflected phases P2P at about offset 60 km shown in Fig. 3a
