Abstract: In 1585,an earthquake with MS53/4 happened in the south of Chaoxian of Anhui Province,and the parameters of this earthquake listed in earthquake catalogues of varied versions are different.According to the detail textual research of the historical earthquake records,the epicenter location of this earthquake is further confirmed by means of field seismo-geological investigation in the Chaohu-Tongling region of the western Changjiang valley.Shallow seismic prospecting and drilling methods are applied to study the buried fault,the possibility of existence of seismogenic fault and fault activity in the western Changjiang valley area are analyzed in depth,and the causative tectonic background of the 1585 MS53/4 south Chaoxian earthquake is studied.The result of this study indicates that the Yanjiaqiao-Fengshahu Fault,which was active in early Pleistocene to mid-Pleistocene,is possibly the causative structure of this earthquake.To identify the seismogenic structure of the 1585 south Chaoxian earthquake is helpful to deeply know the tectonic background of the moderate and small earthquake activities in eastern China.

Key words: historical earthquake verification, seismogenic structure, Chaoxian of Anhui

摘要: 1585年安徽巢县南53/4级地震,各版本地震目录中给出的地震参数不尽一致。文中对该次地震的历史资料进行了考证,进一步核实了该次地震的参数。通过对该地区的野外地质调查,结合在隐伏区的浅层地震勘探与钻探验证等工作,探讨了1585年巢县南地震的构造背景,认为早、中更新世活动的严家桥-枫沙湖断裂可能是该次地震的发震构造。该研究成果有助于加深对中国东部中等和弱地震活动区发震构造背景的认识。
