摘要
对2003年北黄海5.1级地震的地震活动背景、地震序列、震中周围中小地震活动图像及地震学参数等进行了详细分析。认为该次地震为前-主-余型,经历了一个活跃-平静-发震的过程;地震前震中附近出现了孕震空区和一些地震活动性参数异常。
It was analyzed that seismicity background, earthquake sequence, seismicity pattern of moderate- small earthquake around epicenter and seismology parameter of Beihuanghai ML5.1 earthquake in 2003. The result shows that the earthquake sequence is mainly foreshock - mainshock -aftershock type and goes through a process of activity -- quiescence - happening earthquake, appears seismogenic gap around the epicenter as well as some seismicity parameter anomalies before this earthquake.
