本世纪以来塔里木盆地和准噶尔盆地周缘强震活动的初步探讨

PRELIMINARY STUDY OF THE SEISMIC ACTIVITIES OF STRONG EARTHQUAKES ALONG THE MARGIN OF TARIM AND ZHUNGAER BASIN IN THE CENTURY

对本世纪以来塔里木盆地和准噶尔盆地的地震活动特点进行研究,认为M≥6.0地震活动有环绕盆地周缘分布的特点。可以将该区的强震活动分别分为两个活动阶段和六个活动时段。并对各时段地震活动的时空演变进程和今后几年强震活动的趋势进行了分析。

In this paper, the seismic activities of Tarim and Zhungaer Basin in the century are studied. It is considered that the seismic activity of M≥6 earthquakes has the characteristic of distribution along the margin of the two basins. The seismic activity can be divided into two active stages and six active periods. The temporal and spatial evolution process of seismic activity in each period and the tendency of strong earthquake activity in coming years in Xinjiang area has been studied.
