Abstract : This is a preliminary report of results obtained in an investigation of elastic ground waves initiated by a point load (having a Heaviside time variation) acting on the surface of, in particular, an elastic half-space. The results consist of 1. Integral expressions for displacements and associated potentials everywhere in the halfspace for the separate contributions from the P, S, M and Rayleigh surface wave systems. 2. Explicit expressions and curves for the surface displacements for each type of wave. The total surface displacements (evaluated for nu = 1/4) reduce to known expressions obtained by Pekeris. The term 'preliminary report' is intended to imply that the completeness of the solution and the physical interpretation of results will be discussed in subsequent papers. (Author)
