| 摘 要： | 2008年8月5日靖宇-抚松发生Ms4．6级地震。本文对这次地震的区域地质构造、震源机制、地震序列特征等进行了分析。结果表明，此次地震的发震构造是浑江断裂带；震前地震活动呈现“稀疏-密集-平静”特征，余震衰减正常；序列空间位置变化不大，相对集中在北东向条状分布，走向与浑江断裂带一致。

| Abstract: | The Ms4.6 earthquake was occurred between Jingyu and Fusong on Aug.5,2009. The regional geological structure,the focal mechanism,seismic Sequence Characteristics and so on were analylsed in this paper.The results show that the Hunjiang fault zone was the seismotectionnies of this event. Seismic activity emerged＇sparsity-intensiveness-equilibrium＇characteristies. The aftershocks attenuated normally and variation in space of theseearthquakes was not large.The zone fomed by the whole sequence was mainly distributed in NE direction and itsdirectoin was the same as the Hunjiang fault. |
