| 摘 要： | 探讨汶川地震对湖北地震活动的影响，认为龙门山断裂带与襄樊-广济构造带同属于扬子板块西部和北部边缘，是扬子板块逆冲插入青藏板块和秦岭微板块之下形成的。历史强震统计结果表明，四川中西部及周边强震活动对湖北及周边地区中强地震活动影响明显，且对应率较高。汶川地震后3年内，湖北及周边地区具有发生中等强度地震的可能。同时也指出，近几年湖北及周边的地震活动是汶川地震前期东部地区应力场调整的结果。

| Abstract: | Effect of Wenchuan earthquake on Hubei seismic activity is discussed on the basis of the tectonic evolution,the historical seismic activity and seismic focal mechanism solutions and the conclusion considered that Longmenshan fault and the Xiangfan-Guangji tectonic belt are the western and northern marginal belts of the Yangzi plate which thrusts and intervenes downwards the Tibet and Qinling blocks.The statistics of historical strong earthquakes indicate that the strong earthquakes in western Sichuan region... |
