Spectral slope parameter (above) shows no appar- ent functional relationship to azimuth as predicted by theory (notice that the mean slope Is -1,24, well below , which would correspond to a Markov process). The Intercept parameter (below) clearly shows the effect of seafloor anisotropy and generally conforms to the sinu- soidal model. Model parameters are as follows: mean ampli- tude = m, amplitude of sinusoid = m, azimuth of maximum energy = 115' (perpendicular to observed strike). 92
