Contributions to the spectral theory of seismic sources and determination of the parameters of earthquake foci

  • Dumitru Enescu
  • Anca Georgescu


A spectral theory of seismic sources is developed which treats earthquake foci as band-pass filters. This concept is applied to focal mechanisms of the type double-couple with moment, and the obtained spectral function of the source is compared with those obtained by other authors. Finally some formulae for the determination of geometric and dynamic source parameters from the ‘bandpass’ parameters are presented.
