摘要
利用广东省数字地震台网记录的 1999年台湾集集 7 6级地震的波形资料 ,通过频谱分析 ,得出此次地震的震相动力学特征 ,计算出P波和S波的应力降、地震矩、震源尺度等震源参数和介质品质因子Q值 。
The spectral analysis of seismic displacement of the M S7 6 JiJi earthquake is made with the digital seismic data recorded by Guangdong Digital Telemetry Seismograph Network and the dynamic feature of this earthquake phrase is obtained. The seismic moment M 0,stress drop Δσ,source radius a and quality factor Q of P-and S-wave are calculated through the frequency curve. The momental magnitude M W is also given.
