【摘要】 对 1910年以来缅甸转换构造区、滇西南旋转构造域等区域的 7级地震与青藏块体 7级地震的相互关系进行研究 .结果显示 ,青藏块体 7级地震之间具有明显的时空关联性 ;地震活动的主要特点表现为时间上的成丛性、空间上的迁移性及丛内迁移的有序性 ;大部分地震丛以缅甸转换构造区或滇西南地区 7级以上地震为牵头地震 ,沿两条路线向南北带及西藏地区迁移 ,具有较为完整的活动图像 .更多还原

【Abstract】 The correlation of earthquakes with M S≥7.0 in interior Tibet plateau and Burma transform tectonic region,southwestern of Yongnan region is studied. The results show that the spatio temporal correlation is among earthquake very obvious in Tibet plateau and its adjacent regions.The main features of seismicity are cluster in temporal , migration in space and order in migratory route. In each cluster,usually the events first occurred in Burma transform tectonic region and southwestern of Yongnan,then migrate to the Southnorthern Seismic Belt and interior Tibet along two routes,with complete pattern.更多还原
