| 摘 要： | 利用单台数字地震波形资料,开展地震波谱分析。首先选择研究区中2001年以来信噪比较高的68个地震(4.0≥Ms≥3.0),测定地震波谱特征量和应力降,然后讨论这些量随时间的变化特征及其与中强震的对应关系,以此作为监视研究区内应力状态变化的测震学指标。

| Abstract: | The seismic spectrum in south of Kelamayi is analyzed by the single digital seismic wave data. The seismic spectrum characteristic quantity and stress drop are determined by high signal noise ratio （S/N） of 68 earthquakes since 2001 in south of Kelamayi, and the relationship between the characteristics with the time and the middle - strong earthquakes is discussed, which are regarded as seismometry index of stress for eaithquake prediction. |
