M ≥ 7 earthquakes have showed an obvious commensurability and orderliness in China's Xinjiang and its adjacent regions since 1800,with the main orderly values being(30 a)×k(k=1,2,3),11-12 a,41-43 a,18-19 a,and 5-6 a.In the guidance of the information forecasting theory of Weng Wenbo,and by combining ordered network structure analysis with complex network technology,we focus on the prediction summary of M ≥ 7 earthquakes in Xinjiang and its adjacent regions by using the ordered network structure,and add new information to further optimize the network,hence construct the 2D-and 3D-ordered network structure of M ≥ 7 earthquakes.In this paper,the network structure fully revealed the regularity of seismic activity of M ≥ 7 earthquakes in the study region during the past 210 years.Based on this,four M ≥ 7 earthquakes were predicted successfully in turn in this region,namely the Karakorum M7.1 earthquake in 1996,the M7.9 earthquake in the junction area of Russia,Mongolia,and China in 2003,and the two Yutian M 7.3 earthquakes in 2008 and 2014.At the same time,a new prediction result is presented that the future two M ≥ 7 earthquakes will probably occur around 2019-2020 and 2025-2026 in the research region.The results show that large earthquake occurred in defined region can be predicted.The method of ordered network structure analysis produces satisfactory results for the moderate and long term prediction of M ≥ 7 earthquake.
