| 摘 要： | 强震活动状态分析与研究是地震形势跟踪分析的重要基础,以频次的角度分析和探讨青藏块体的强震状态特征,研究表明,青藏块体存在强震平静与活跃交替活动的状态特征,已经历5个平静与活跃交替活动的状态过程.2008年3月21日于田7.3级地震、5月12日汶川8.0级地震和2010年4月14日玉树7.1级地震的发生表明青藏块体强震活动已处于活跃状态.

| Abstract: | It＇s important basic for seismic trend analysis and judgment that earthquake state of strong seismicity analyzed and researched. State of strong seismicity of Qinghai-Tibet block have analyzed and discussed by the large earthquake frequency. The result shows five seismic activity state and calm state periods of Qinghai-Tibet block. The new seismic activity state came for Qinghai-Tibet block with the Wenchuan M 8.0 earthquake on May 12, 2008 and the Yushu M 7.1 earthquake on April 14, 2010. |
