The past earthquake events being taken as a random time series, the occurred time of future great earthquakes greater than a given magnitude can be extrapolated "by filtering based on separated magnitude and linear prediction method. For this purposes, the autocorrelation of the historical earthquake time series and the cross correlation function between the historical earthquake time series and great earthquake ’ Signal’ series being calculated, the kernel function of optimal linear filtering and prediction operator are obtained by substitution into an integral equation. Predicting results of some great earthquakes in the North-South Seismic Belt in Central China, Northern China Seismic Belt and the Tienshan Seismic Belt of North-Western China are given in this paper.
