Two complementary derivations, one in terms of slowness, one in terms of phase velocity, leading to dual forms of parametric equations for the general head wave envelope, occasioned by a point source of loading on an elastic half-space of arbitnry anistropy, are presented.
The two sets of equations are shown to be consistent and the special case of isotropy is used to verify the alternative formulations.
