摘要: 系统研究了1925年以来云南及邻区5级以上地震的时间分布特征, 分别给出了云南及邻区5级以上地震连发和平静的定义。 分析了中强震连发、 平静的一些基本特征, 研究了5级以上地震连发、 平静事件与该区强震活跃、 平静过程的关系。 这些分析结果对云南及邻区的地震趋势预测有一定实际意义。

关键词: 云南及邻区, 中强震连发, 中强震平静, 强震活跃期, 强震平静期

Abstract: The characteristics of time distribution of M≥5.0 earthquakes occurred in Yunnan and its neighboring region since 1925 are systematically studied. The definitions of successive occurrence and the quietness of M≥5.0 earthquakes occurred in Yunnan and its neighboring region are separately put forward. The basic features of successive occurrence and the quietness of moderately strong earthquakes are analyzed and the relation between the events of successive occurrence and quietness and the active-quiet process of strong earthquake is studied. The analytical results contribute a certain practical significance to the prediction of the earthquake trend.

Key words: Yunnan and its neighboring region, Quietness of moderate earthquake, Active period of strong earthquake, quiet period of strong earthquake
