Algorithms and methods for the numerical simulation of seismic wave fields in cavernous zones

A developed toolkit (parallel programs and visualization tools) for the numerical simulation of the elastic wave propagation in 3D and 2D nonhomogeneous elastic media, comprising cavernous inclusions applicable to the on-site inspection, is described. According to the results obtained, groups of waves were identified, and synthetic data reflecting the influence of a cavernous inclusion upon the general picture of wave field were interpreted. Application of the cluster supercomputer NKS-30T favored to successful investigations.
