Abstract：The great scale earthquake is meant by that the earthquake has very long geneseismic fault, very large fault plane and very big moment magnitude denoted by Mw 9 and more. Some correlation between the great scale earthquakes and temperature decrease in the northern hemisphere, including China,is indicated. Besides, the great scale earthquakes are in some degree related to the catastrophic flood in China. The great scale earthquake Mw 9.0 in Indonesia in 2004 is an important warning for us.
