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
