- A fundamental theory of evolutionary stochastic waves is developed and a technique for digitally generating samples of such waves is introduced as an extension of the spectral representation method. This is done primarily for the purpose of developing an analytical model of seismic waves that can account for their stochastic characteristics in the time and space domain. From this model, the corresponding sample seismic waves can be digitally generated. The efficacy of this new technique is demonstrated with the aid of a numerical example in which a sample of a specially two-dimensional stochastic wave consistent with the Lotung, Taiwan dense array data is digitally generated.
