数字化地震数据与震源参数的测定——广东河源地震的震例分析

Digital seismic data analogy and focal parameter estimation, talking Heyuan earthquake, Guangdong as an example.

以发生在广东省河源地区的地震为例 ,展示如何利用数字化地震数据进行波谱分析及震源参数估算 ,并对该区的地震破裂模式作了初步的分析。利用上述结果 ,建立了地震矩M0 与震级ML 的关系式 ,以便利用震级ML

As an example, the digital recordings of earthquakes occurred in Heyuan, Guangdong were done its wave spectrum analogy and focal parameter estimation, and gave preliminary analogy of earthquake fracture mode in the region. Using above result, we establish the relation of seismic moment M 0 and M L, and can estimate moment magnitude M W fromM L.
