摘要: 通过应用最大精谱法、有序聚类法和地震活动过程、地震相关性的分析,论证了华东地区正处于1971年以来的地震活动幕后期,具有发生6级以上地震的可能。1996年11月9日南黄海6.1级地震的发生与这一分析基本相符.作者还就地震大形势分析的有关科学问题进行了讨论。

Abstract: By using the maximum entropy spectrum method ,ordered clustering procedure ,seis­micity process and earthquake correlatability method, the author proposed that East China is now situated in the late period of the seismically active episode, which began from 1971, and there is a possibility of occurring M > 6 The occurrence of South Yellow Sea earth­quake with M = 6. 1 on November 9, 1996 ,is according to the above-mentioned analysis. In this paper, the relevant scientific problems concerning earthquake trend analysis have been discussed as well.

Key words: Seismic activity, Maximum entropy spectrum analysis, Correlatabillty, East China
