| 摘 要： | 本文主要根据云南历史和现代的地震活动情况，总结提出了云南地震活动具有频度高，强度大、震源浅和破坏性大的特征。强震的类型可分为主震型和主震余震型两类，本世纪以亚强震活动具有沿逆时针方向迁移的特征。本文初步对这些地震活动特征的形成原因作了一些分析探讨，最后根据这些地震活动特征提出了云南地区地震预报的一些对策。

| Abstract: | This paper sums up the activities of historical and modern earthquakes in YunnanProvince and suggest that the seismicities in the regbnare characterized by high frequency,large magnitude,shallow source and strong disruption.The strong earthquakes can be dividedinto mainshock and mainshock-aftershock sequences. Since the present century,the activities ofstrong earthquakes tend to migrate in counterclockwise direction. In addition,authors analyzeand discuss prelnninarily the causes of the seismicities,and put forward some earthquakesprediction countermeasures for Yunnan region based on these seismicity characters. |
