云南历史强震活动图象

摘要
本文讨论了云南历史强震成带性、群发性和中强震的随机性，以及强震类型的地域差异。指出：在地震预测及设防中，应着重考虑主要地震带区；一次５～６级之后，要预防接踵而至的更强地震；全省以高原坝子（盆地）为依托的城镇均应考虑地震设防；滇东。滇西强震类型迥异，前者一般为主震─－余震型，后者多表现为前震─－双主震─－余震型或者震群。
This paper discusses the characteristics of historical strong earthquakes in Yunnan,including earthquake distribution in belts,seismic swarm,random of moderate strong earthquakes and difference of strong earthquake patterns in regions. The authors point out that major seismic belts should be taken into account In earthquake prediction and earthquake resistance and protection; the following strong earthquake should be taken precaution against after a event with M=5-6;earthquake resistance and prediction of the cities and towns of Yunnan lain in plateau basins should be taken into account;the strong earthquake pattern in east Yunnan differed greatly from that in west Yunnan and the former was generally mainshock- aftershock, and the latter,often foreshock-double mainshock -aftershock or earthquake swarm.
