| 摘 要： | 在分析 190 0年以来中国大陆西部特大地震 (MS≥ 7 5 )的时空分布特征的基础上 ,进一步研究了大陆西部特大地震与大华北地区强震 (MS≥ 6 0 )活动的相关特征 ,结果表明 :地震构造对西部的强震活动显示出很强的控制力 ;大华北强震与西部特大地震具有同步活动特点 ,但滞后于西部的地震活动 ;西部特大地震第 3活跃时段已经开始 ,但大华北地区出现 6级以上地震的连发还为时尚早

| Abstract: | Based on the analysis of temporal and spatial distribution of great earthquakes ( M S≥7.5) in West China since 1900, the correlation between great earthquake activity in West China and strong earthquake ( M S≥6.0) activity in North China is studied. The result shows that the activity of great earthquakes in West China is controlled by the seismotectonics of the region. Seismic activities in each active period of great earthquake in West China almost occur successively or in cluster within the same s |
