| 摘要: |
| 按照最大化利用有限地震资料的研究思路，充分发掘可利用信息，综合文史记载、人文历史、地震研究成果等资料，对2次江西早期中强地震进行甄别和参数复核，得到结果如下：304年吉水-永丰间地震的震中约为27.3°N、115.2°E，震级5.0级左右；455年余干地震的震中约为28.7°N、116.7°E，震级5 1/2级左右。该结果可为江西早期地震研究和潜在震源区划分提供新的资料。 |

| Abstract: |
| In this paper,we used the extremely limited valuable seismic data,and fully exploited the available information in the concise description of the earthquake,to screen and parameterize two early moderate-strong earthquakes in Jiangxi Province based on comprehensive literature and history records,human history,and earthquake research results. We concluded that the Jishui-Yongfeng earthquake in A.D.304 are located at 27.3°N and 115.3°E with the magnitude of MS5. The Yugan earthquake in A.D.455 are located at 28.7°N and 116.7°E,with the magnitude of MS5 1/2. This work can provide new information for the historical earthquake research and the division of potential source areas in Jiangxi Province. |
