| 摘 要： | 采用谱分析方法，利用山东数字地震台网的观测资料，计算了2004～2007年期间山东地区44次3级以上地震的波谱，估算了地震矩、拐角频率、应力降、震源破裂半径，讨论了各震源参数之间的相互关系以及拐角频率的时间分布特征。分析结果表明，地震矩与震级、地震矩与拐角频率、地震矩与震源破裂半径有明显的依赖关系。

| Abstract: | Using the observational data of the Shandong regional digital seismographic network, the seismic waveform spectra are calculated by use of the data records of 44 earthquakes with magnitude equal to or greater than 3 in Shandong region in the period from 2004 to 2007. The seismic moment, corner frequency, stress drop, source radius of each earthquake are roughly estimated. The relations between the source parameters are discussed and the characters of the corner frequency distribution with time are analyzed. The results show the marked dependence of the seismic moment on the magnitude, the seismic moment on the corner frequency and the seismic moment on the source radius. |
