| 摘 要： | 本文通过对民国时期发生在滇西南地区的1938年5月14日澜沧MS6.0级、1941年5月16日耿马MS7.0级和1941年12月26日澜沧MS7.0级3次地震历史资料的系统收集和整理,并在前人已有研究的基础上,通过现场采访和补充调查获得的新资料,修改和完善了这3次地震的等震线图和极震区范围,并结合该区地形地貌特征和断裂最新活动性研究结果,综合分析评述了其发震构造特征。结果表明,这3次强震发生在腾冲-澜沧新生地震带附近,分别与黑河断裂、南汀河断裂西支及澜沧断裂勐遮段的新活动密切相关。

| Abstract: | Based on the historical earthquake documents of three earthquakes occurred in southwest Yunnan province during the Republican- period of China, i.e. Lancang MS6.0 on May 14th, 1938, Gengma MS7.0 on May. 16th, 1941, and Lancang MS7.0 on Dec. 26th, 1941, and the previous research as well as the site inspection and interview, we got supplementary information about these three historical earthquakes. In this study, we modify the isoseismal line and meizoseismal area distribution. By comprehensive analysis and the study of characteristics of landform and geomorphic features as well as the newest fault activity research, we summarized the characteristics of seismogenic structure for these three earthquakes. Our results show that these three earthquakes occurred near newly born Tengchong-Lancang seismic zone and are closely related to the recent activity of Heihe fault, the west Nanting river brunch fault and the Mengzhe segment of Lancang fault respectively. |
