Figure 6. (a) The fits of the standard model (lines) to the data (dotted lines and *).
The data consist of the average spectral amplitudes for the frequency band
1–5 Hz plotted for each of the 43 events. The vertical axes are spectral
amplitudes and the horizontal axes are station numbers.

station 18 is to the south at Seal Beach. Note that the standard model does not
fit the group of arrivals at = 111–117°. (b) The
