In this paper a new method is developed for solving the dynamic problems of elastic wave propagation. It is suitable for tayered media and buried point source model. The method is based on a combination of partial separation of variables and finite difference techniques. It has wide zene of computational freqtcency, high accuracy and good stability. For examining the efficiencg of this method,numerical results of a multilayered media model are given.
