【摘要】 历史地震核查就是核查地震的宏观震中,而宏观震中应是地震能量的辐射中心。由于过去在认识上的误区,在历史地震的确定中,往往把破坏最大的地区定为震中,这样就有可能把地震诱发的地质灾害定为震中。1558年,在广东省的西部与广西省交界处发生了一次中强地震,在1995年出版的"中国历史强震目录"中,将其震中定位于封川。本文通过查阅有关的县志和府志,阐述了地震发生时的人文环境,包括行政建制、政治局势、经济与文化、地质条件以及各地间的关系等,同时还结合地震破坏的地基条件和单边地震记载点的分析,认为以上所确定的地震震中,仅是地震所诱发的地质灾害,而不是地震的辐射中心——释放能量最大的地区。同时,通过1558年地震记载点与1584年肇庆2个地震记载点的比较,说明了这些地震的震中相近。最后,根据地震影响范围(地震记载点)确定了1558年地震的参数。更多还原

【Abstract】 The main task of historical earthquake investigation is to locate the macro-epicenter, which is the center of energy radiation. In the past, false recognition of the epicenter often occurred when we treated the most destructive area as the earthquake center, which may be the results of geological hazard induced by earthquake. Based on the historical record, a moderate earthquake occurred in 1558 in Fengkai, Guangdong province, in which the epicenter was believed to be located in Fengkai in "The catalogue of Historical Earthquakes of China" published in 1995. Our recent results from the comprehensive investigation suggest that such so-called "epicenter" is merely the place where great geological hazard induced by earthquake occurred, rather than the earthquake radiant center from which largest energy released. Finally, according the earthquake affected area (recorded points), the parameters of the earthquake in 1558 was determined in this paper.更多还原
