Research on nonlinearR/S method and its application in earthquake prediction

The preliminary result of this work was obtained in 1992. At Consulting Meeting for Seismic Trends of China in Jan. 1993, we handed in a report and predicted that “Until now, the average magnitude curve\(\bar M\) haven’t gotten risen again after a fall, and the value ofH is under 0.4, so no alarm is made by each of these two. We predicted that, seismicity of the Chinese mainland in 1993 may be at the same level as in 1991–1992, or a little higher than it, but mustn’t be very high; this is to say that no earthquake withM s⩾7.2 will occur in the Chinese mainland in 1993.”
