According to the statistical analysis,a total of 23 M≥8 earthquakes occurred in mainland China from 1303 to 2012.The seismic activity of M≥8 earthquakes has showed an obvious self-organized orderliness.It should be remarked especially that,there were three ordered pairs of M≥8 earthquakes occurred in west China during 1902-2001,of which,the time interval of two earthquakes in each pair was four years.This is a unique and rare earthquake example in earthquake history of China and the whole world.In the guidance of the information forecasting theory of WENG Wenbo,based on previous research results,combining ordered analysis with complex network technology,we focus on the summary of the ordered network structure of M≥8 earthquakes,and add new information to further optimize network,hence construct the 2D-and 3D-ordered network structure of M≥8 earthquakes and make prediction research.At last,a new prediction opinion is presented that the future ordered pair of M≥8 earthquakes will probably occur around 2022 and 2026 in west China.
