| 摘 要： | 简要介绍了2008年8月30日新疆和静MS5.6地震的基本参数、震源机制解、地震序列特征和局部构造应力场等,分析了地震前震源区周围及相关构造区域出现的中、短期地震活动异常特征。结果显示,该序列为主-余型,余震活动呈间歇式,衰减迅速,震源断错性质为走滑型。震前震源区东侧存在长时间4级地震平静、3级地震围空及多台地震波振幅比的异常等现象,同时在地震发生前1~3个月出现了短期异常,表现为振幅比异常的回返、空区瓦解和地震窗的异常。依据多种异常变化,在震前对该地震做出了三要素准确的短期预报。

| Abstract: | The author introduces briefly the basic parameters,focal mechanism solution,sequence character and local tectonic stress field of Hejing MS5.6 earthquake on August 30,2008 etc.,and analyzes the middle and short term seismic anomaly characteristics in the source region and its surroundings and related tectonic belt before Hejing MS5.6 earthquake.The result shows that MS5.6 earthquake sequence is main-aftershock type,and the aftershock activity is intermittent and attenuates rapidly,and the focal dislocation ... |
