review text: We present a spectral element method for studying acoustic wave propagation in complex geological structures. Due to complexity (both lithological and stratigraphical), the use of numerical methods of higher accuracy and flexibility is needed to achieve the correct results. The spectral element method shows accurate results even for rather long wave propagation times, and dispersion errors are essentially eliminated; irregular interfaces between different media can be well described so that numerical artifacts or noises are not introduced. The method is tested against analytical solutions both in the two-dimensional homogeneous and heterogeneous media.
