本文使用1970年以来全球较大地震资料,从时空分布和活动频度图象等资料分析研究了1986年全球及中国内陆的地震活动,预计1987年全球无8级以上地震。并指出我国大华北、东北北部,汾渭河谷及东南沿海一带的地震活动比1986年有所增强。
In this paper, we use the larger earthquakes in the world since 1970 to analyze the earthquakes in 1986 and the inland China from the spatial and temporal distributions and the frequency of active images. It is estimated that there are no earthquakes of magnitude 8 or above in the world in 1987. And pointed out that the seismic activity in North China, North China, Fenwei Valley and the southeast coast of our country has been strengthened compared with 1986.
