Abstract
The problem of the propagation of seismic waves in the Earth is studied. The authors propose a method to simulate numerically dynamic processes based on the solution to determine the system of elastic body equations by a grid-characteristic method on structural curvilinear computational meshes. A set of calculations of the propagation of a perturbation (set as a local extension area) in a layered two-dimensional Earth model are carried out. Wave patterns and characteristics of wave responses are compared to analytical solutions and the published analogous results.
