The propagation of elastic waves in a multilayered geological environment is analyzed based on the theory of generalized-rays and the method of Lamb-Cagniard-Pekeris. The waves are generated by an underground explosion which is approximated by a point source. Velocity responses at receivers at ranges about one to three times the thickness of the source layer are calculated with a new computer code. The results are exact within the framework of the theory of elastic waves. Comparisons of the calculated results with the observations made at the Nevada Test Site in 1966 show considerable discrepencies. Author
