赣南地区历史地震补充研究

Supplementary investigation of historical earthquakes in southern Jiangxi

  • 摘要: 通过对赣南地区历史地震资料系统地调查研究,以地域人文背景、史志记载情况等为切入点,综合考证历史地震记载的完整性,并在充分挖掘可用信息的基础上,对公元412年、1603年、1847年和1888年等历史地震事件进行了甄别和参数核定。研究表明,公元1500年之后赣南地区的地震记载相对较连续;区内地震活动呈自东南向西北逐渐减弱的趋势,且地震主要分布在NE或NNE向主干断裂附近,以及主干断裂与NW向断裂的交接复合地区;原地重复发生地震的频率相对较高。该结果可用于修定新版地震目录、开展重大建设项目工程场地的地震安全性评价及历史地震调查等工作中,为区域地震活动性研究、防震减灾规划决策等提供基础依据。

     

    Abstract: Based on the systematic investigation and research on the historical seismic data in the southern Jiangxi, we tackled comprehensively the integrity of historical earthquake record starting from the regional cultural background and historical records. Then on the basis of fully tapping of the available information, we made the discrimination and parameters verification for the historical earthquakes in AD 412, 1603, 1847 and 1888.The results show that the earthquake records in southern Jiangxi were relatively continuous after AD 1500. The seismic activity in the studied area is mainly characterized by gradually weakening from southeast to northwest, and the earthquakes mainly distributed in the vicinity of NE or NNE-trending main faults, as well as the intersection of the main faults and the NW-trending faults. The frequency of in-situ repeated earthquakes is relatively high. The results can be used to revise the new edition of earthquake catalogue, carry out seismic safety evaluation and historical seismic survey of engineering sites of major construction projects, and provide basic foundation for regional seismicity research, planning and decision-making of earthquake prevention and disaster reduction.
