克拉玛依南地震波谱变化初探
|
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。
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 earthquake prediction.
