Figure 10. (a) Low-frequency (1–5 Hz) S-wave spectral amplitudes plotted
in the format described in
Figure 6. Backazimuths between
120° and 124° (events 17–22) exhibit a spike at station 11. A
caustic (equation 9) is included
in the model for events 17–22. (b) High-frequency (5–10 Hz)
S-wave spectral amplitudes plotted in the format described in
Figure 6. Backazimuths between
120° and 124° (events 17–22) exhibit a spike at station 11. A
caustic (equation 9) is included
