| 摘 要： | 分析了这次地震的宏观影响场,地质构造及地震序列等特征,结果表明,这次地震的ＶＩ度极震区为ＮＷ走向,范围较大但破坏相对较轻,震源深度达１０ｋｍ左右。这次地震的发生可能和新丰江地区ＮＮＷ向的断裂活动有关。

| Abstract: | The features of marcroseismic influence field,the geologic structure and the earthquake sequence and so on of the M L 4 9 Xinfengjiang earthquake are analyzed.The results show that the area of meizoseismal region with NW strike was bigger,but the damages caused by this event are relative slight.The focus depth of the earthquake was about 10km,and the earthquake occurred have probable a relation with the activity of the faults in NNW strike in Xingfengjiang region. |
