Numerical experiments have been conducted to study the effects of anisotropy for a seismic source in an anisotropic medium. An algorithm has been developed to compute complete seismic waveforms in general anisotropic media [Mandai and Toksoz, 1990]. Using this tool, we have shown that placing the source in an anisotropic medium affects the seismic waveforms significantly. An explosive source in an anisotropic medium produces an azimuthally dependent radiation pattern, for P, SV, and Rayleigh waves, and also generates SH waves. In some cases of anisotropy, the radiation pattern may be similar to those of earthquakes.
