A historical and procedural outline is presented of several methods of solving problems of elastic wave propagation from impulsive sources. The methods include a summary of the formalism of the geometrical theory of diffraction, eigenvalue methods, and many others, all of which are used to solve the boundary value problems of elastic wave propagation. The mediums considered are homogeneous or inhomogenous in composition; the geometries are plane‐parallel and multilayered, or spherical (cylindrical) in analogy with the earth.
