摘要
总结了中国大陆8级地震活动的基本特征,30年、53年及100年周期性,百年主体活动区及其格局变动,大地震空段填位及迁移,成组性,几十年多阶段强震释放特征及其连发、复发特点。根据当前地震活动图像异常评估认为,未来1～5年中国大陆喜马拉雅山带西段可能发生7 12～8级地震,以及新疆,川、滇4处为注意地段。
The author summarized M8 earthquake activity pattern characteristics in China's Mainland such as the periodicity（30 years,53 years and 100 years）,One hundred year of main active area and its pattern change,strong earthquake empty section filling and migration,group activity,many stage strong earthquake release characteristics of several decades and successive occurrence,recurrence characteristics.According to the current seismicity pattern anomaly,in future 5 years there will be 7.5 to 8.0 earthquake occurring in the western part of the Himalayas belt in China's Mainland and Xinjiang,Sichuan and Yunnan are the noticeable areas.
