| Abstract: | The change of the focal mechanism solution is the important basis of the earthquake sequence for post-earthquake judgment. The phenomenon of the focal mechanism solution consistent occurs before many devastating earthquake sequences. Rapidly calculating the focal mechanism solution of earthquakes sequence changes is significant in earthquake prediction research. The correlation coefficients of that the sequential seismic body-wave observes zero frequency spectrums reflect the factorial similarity of earthquake focus radiation pattern, that is, the similarity of focal mechanism solution. Therefore, utilizing the related coefficients of body-wave spectrum amplitude of sequential earthquake is the important basis of the seismic sequence for post--earthquake judgment. After the occurrence of seismic sequence, the cal- culator program of the correlation coefficient of body-waee spectrum amplitude reads its data of seismic waveform, rapidly calculates the related coefficients, draws the sequence chart or cluster chart of the related coefficients of slide, judges the degree of consistency of focal mechanism, which provides evidence for post-earthquake judgment of seismic sequence. |
