Figure 4From: Q P structure of the accretionary wedge in the Kumano Basin, Nankai Trough, Japan, revealed by long-offset walk-away VSP Stacked seismic traces. Traces in G2 are exaggerated by a factor of 10, and the G3 and MSF traces are exaggerated by a factor of 40. Red trace indicates the reference waveform (R) used for the calculation of spectral ratios. Vertical line indicates the picked arrival time of the first arrivals from refracted waves and the reflection arrival times from the reflected arrivals from the megasplay fault.Back to article page
