辽宁地区1509年4月21日和1552年10月27日地震考证

Verification of Historical Earthquakes in 1509 and 1552 in Liaoning Area

辽宁是历史地震资料比较缺乏的地区,深入研究历史疑难地震,尤其是确认一些破坏性地震,对补充已有的地震目录和开展地震预测及工程场地地震安全性评价有重要作用。在历史地震研究中认真考查,论证已有的地震史料是最主要的手段和方法。但是若能在此基础上,利用现代地震资料,按"地震重复"发生理论反推一些历史上可能存在的破坏性地震,也可以认为是对历史地震研究方法的一种补充。按照这一思路,本文在进一步分析地震史料的基础上,通过与现代地震活动图像和大地震震害现象的对比,确认辽宁地区1509年4月21日的地震是一次破坏性地震,并对1552年10月27日的地震做了讨论。

Liaoning region is short of the historical earthquake data. It is important to study the historical earthquakes, especially to confirm some destructive earthquakes, which played the important role in adding some existing earthquake catalogues and setting up earthquake forecast and earthquake safety evaluation of engineering sites. Based on the theory of earthquake recurrence, it is likely that we can take advantage of the modem earthquake data to trace back some destructive earthquakes which occurred in history without record. In this paper we confirmed that the earthquake occurred in Liaoning district in 1509 was a destructive earthquake, and also made a discussion on the earthquake which occurred in 1552.
