Figure 2

Common shot gather obtained by WVSP. A reduction velocity of 4 km/s is used, and no filter is applied. Thin solid black lines mark bins for trace stacking. Trace groups G1, G2, and G3 correspond to down-going direct waves, diving waves through the lower part of the L2 layer, and refracted waves from L3. Clear later arrivals are interpreted as reflection arrivals from the megasplay fault (MSF).
