A shear wave with arbitrary polarization from a distant earthquake and approaching the surface through an anisotropic layer will split into two orthogonally polarized quasi-shear waves that propagate with slightly different speeds. In the earth, the faster of these typically will arrive before the slower by 1 s or less, but in rare cases by 2 s (or more). The difference in arrival times depends on both the degree to which the material is anisotropic to propagation in the vertical direction and the thickness of anisotropic layer.

47. Stern et al. (11) reported P-wave residuals from three earthquakes lying northwest of New Zealand and recorded by a subset of stations along two lines across New Zealand (Fig. 3), used to determine the crustal structure (30). They present details of the analysis summarized here.
