| 摘 要： | 九江—瑞昌5.7级地震是赣西北少震区百年不遇的一次中强破坏性地震,震中烈度大于Ⅶ度。以现场观测资料为依据,从仪器记录的地震波形特点、震级频度关系、地震活动图像等分析了此次地震序列的时空强活动特征。在此基础上结合地震影响场、震源机制解和地震构造环境等讨论了与地震成因相关的一些问题。

| Abstract: | The Jiujing-Ruichang earthquake with MS 5.7 was a destructive medium-strong shock,which was a rare event in the weak earthquake areas in Central and South China.Based on the field observation data recorded by seismograph,including the magnitude-frequency relation,seismic pattern and seismic-waveform,the characteristics of the seismic sequence were analyzed.Moreover,by combining with the influence field,seismotectonic environment and focal mechanism solution,some problems related to seismogenesis are also discussed in this paper. |
