十九世纪中、末期,桂东南和粤西交界地域,曾发生过三次破坏性地震。其中:1890年8月29日地震,震级5 3/4级,有感范围遍及两广三十余县、市。《中国地震资料年表》和《中国地震目录》均未收编;而已出版的个人著作及其他资料、文献,对该地震震中定的差距甚大。限于地方志书对震害描述详略不一,且地方志书多为事后追记,县志、府志难免有互相抄袭之弊,笔者认为单从收集的史料圈定震中未必准确。地震总是在断裂带强烈活动下才发生的。构造带的展布、地震序列是圈定历史地震震中的重要条件。
In the middle and late nineteenth century, the southeastern Guangxi and the western Guangdong border areas, there have been three devastating earthquakes. Among them: August 29, 1890 earthquake, magnitude 5 3/4, a sense of area throughout the more than 30 counties and cities in Guangdong and Guangxi. Neither the Chronology of China Earthquake Data nor the Catalog of Earthquakes in China has been compiled yet. The published individual works and other materials and documents have greatly disproportionately missed the epicenter of the earthquake. Due to the fact that the local history books describe the earthquake damage in different ways and the local history books mostly follow the postscripts, the county and government records are inevitably plagiarized. In the author’s opinion, it is not necessarily true that the historical data collected from the epicenter may not be accurate. Earthquakes always occur with intense activity in the fault zone. The distribution of tectonic belts and seismic sequences are the important conditions for delineating the epicenter of historical earthquakes.
