SUMMARY Surface waves on the Earth propagate nearly on the great circle, if the anisotropy and the lateral heterogeneity are weak. Path and amplitude anomalies are approximately expressed as the intergral along the great circle. the integrand includes derivatives of the phase velocity with respect to colatitude, longitude and azimuth.
