Abstract
A new method of calculation of theoretical seismograms is proposed, which is based on space-time Gaussian beams. The method permits one to overcome the difficulties of calculation of the wave field near caustics and does not contain any calculations of Fourier transforms. Numerical experiments confirm the efficiency of the method for the calculation of theoretical seismograms.
