【摘要】 依据震源理论 ,根据我国数字化地震台网目前的实际情况 ,在前人研究成果的基础上 ,提出一种用Pg波初动求中小地震震源参数的实用方法。可以用三个台的Pg波初动 (初动峰值和峰值时间 ) ,较简便地计算出地震的震源参数 ,从而为以震源和介质动态变化为依据的地震预报 ,提供一个用于日常监测预报的方法。更多还原

【Abstract】 On the basis of the source theory and the predecessors’ researches, considering the present conditions of the digital seismograph network in China, a useful met hod to the determination of source parameters of small and moderate earthquakes is given in this paper. These source parameters can be conveniently calculated w ith the peak values and the peak duration of the first motion of Pg wave recorde d by 3 digital seismic stations. Furthermore, These parameters will Surely co ntribute to the earthquake prediction that is based on the dynamic variation of source and medium.更多还原
