摘要

    摘要
  • 摘要: 基于P波和S波的谱震级特征对汶川地震进行了定量研究,可以看出P波和S波的最大谱震级出现在不同的周期上。对这一现象的构造物理意义进行了讨论,推测相对于P波而言,地震发生期间辐射的S波能量来自异常大的震源体积。选择部分全球地震的谱特征为背景,对汶川地震的体波谱震级特征进行了分析,结论是汶川地震的特征与其所处的周边环境是一致的。
    Abstract: The Sichuan earthquake is quantified on the basis of its spectral magnitudes of the P-and of the S-waves.The maximum spectral magnitudes of the two waves are seen to occur at different periods.The tectonophysical significance of the finding is discussed, and it is deduced from it that the S-wave energy radiated during the earthquake was drawn from unusually large volume, if compared to the volume corresponding to the P-waves.The spectral features of the body waves of the Sichuan earthquake are analysed on the background of the spectral features of a selection of worldwide earthquakes.As a result it is concluded that the Sichuan earthquake fits well into the features of the earthquakes in the surrounding regions.
