摘要: 在对我国西部本世纪第五个地震活跃幕以来地震群体活动时空强演变规律回顾的基础上,研究了近1-2年中强地震的分布特点,结合大地形变的演变状况,对本区地震活动进行了研究,并认为本区处于本活跃幕末的翘尾活动阶段。

Abstract: Based on the time-space intensity evolution of grouping seismieity during the seismieally fifth active period since this century in western China,the distribution characteristies of moderately earthquakes in last 2 years has been studied.Combining with evolutional situation of geodetic deformation,the seismic aetivity is researehed in the area.The conelusion is drawn as follows:the seismieally aetive period is being in lastre-aetivatedstage.

Key words: Seismieally active period, Seismic aetivity, Geodetie deformation, Indianplate, Qinghai-Xizangbloek
