【Abstract】 Using the data of the Ms≥4.7 earthquake catalogues since 1900 the paper systematically analyzed the synchronous fluctuation phenomena of the moderate-strong earthquake in South Huanghai and its coast re-gion,and the border of Shanxi.Hebei and Mongolia which the seismicity rises one after another,and echoseach other at a distance. The phenomena may provide a evidence of the seismic trend prediction for future 2～3years in these regions. The paper gave the prediction version,outlined the applied examples,and discussedrelative problems.更多还原
