Abstract: A direct dynamic problem of the theory of elasticity is considered, which models the formation of seismic wave fields from earthquakes that occur during tectonic processes in the lower layers of Earth’s crust. The numerical solution to the stated problem is based on the method of complexing the analytical Laguerre transform and the finite difference method. A series of numerical calculations for a test model of media has been carried out.

Keywords: elastic medium, longitudinal wave, earthquakes, direct problem, Laguerre transform, difference scheme
