Abstract

We review recent progress in the theory on free oscillations of an aspherical Earth. Effects of asphericity (rotation, hydrostatic ellipticity, lateral heterogeneity and anisotropy) are treated in terms of the perturbation theory. For large angular order, free oscillations are related to surface waves.
