【摘要】 依据随州三里岗ML4.7地震序列的地震监测和宏观调查所获得的基础资料,对此次地震序列的时空强特征及地震成因机理进行了分析。为使地震资料准确可靠,对混淆在序列中的爆破波形与地震波形进行了鉴别和剔除。结合这些基础资料和震源机制解结果。分析认为随州地震序列在成因上与该地区存在的北东和北西向两组断裂构造有关,但主发震构造是北西向断裂。更多还原

【Abstract】 On the basis of the monitoring and macroexamination,the spacetime-intensity characteristics and the genetic mechanics of the Suizhou ML4.7 earthquake are analysed and discussed.At the same time,the seismic waves are compared with the blasting vibration recorded at the seismostation in Suizhou.From the result of analyzing the basic data and focal mechanism,main seismogenic tectonic of the seismic sequence is the NW fault zone in this area,meanwhile it is also related to a group NE faults.更多还原
