本文对我国西南及缅甸部分地区7级以上强震的分布及震前中强地震活动进行了分析研究,从而得出:1.强震发生之前中强地震在空间上呈现两种分布形式,一种分布于极震区端点的延长线上,另一种则散乱地分布于震区附近;2.中强地震断层面积出现峰值点的当年及次年将在云南、四川发生7级以上强震;3.云南与缅甸强震的发生在时间上存在着交替性,即缅甸强震的活跃期是云南强震的平静期;4.云南与缅甸中强地震的发震频次与强震的分布具有一定的规律性,当缅甸境内中强震频度高于云南,则未来强震在云南发生;当云南境内中强震频度高于缅甸,则强震将发生在缅甸。
This paper analyzes the distribution of strong earthquakes above the 7th magnitude in some areas of southwest China and Myanmar and the seismic activity before the strong earthquakes, and draws the following conclusions: 1. Before the strong earthquakes, the moderately strong earthquakes have two kinds of spatial distributions, one Species distributed in the extension of the extreme earthquakes endpoint, the other is scattered in the vicinity of the earthquake area; 2. The area of ?? the peak area of ?? the peak of the peak of the current year and the following year will occur in Yunnan, Sichuan earthquake magnitude 7 ; 3. The occurrence of strong earthquakes in Yunnan and Myanmar alternated in time, that is, the active period of the strong earthquakes in Myanmar was the quiet period of the strong earthquakes in Yunnan; 4. The frequency of seismogenic events and the distribution of strong earthquakes in the moderate-strong earthquakes in Yunnan and Myanmar With a certain regularity. When the frequency of moderate-strong earthquakes in Myanmar is higher than that in Yunnan, the future strong earthquakes will occur in Yunnan. When the moderate earthquakes occur more frequently in Myanmar than in Myanmar, the strong earthquakes will occur in Myanmar.
