Simulation of seismic processes inside the planet using hybrid grid-characteristic method

The problem of the seismic wave's propagation in the Earth is studied. Authors proposed a method for numerical simulation of dynamic processes based on the solution of govern system of elastic equations with grid-characteristic method on structural curvilinear meshes. A set of calculations with the elastic perturbation (local extension area) in layered two-dimensional Earth model was carried out. Comparison of wave patterns and characteristics of wave responses with analytical solutions and published analogous results was done.
