天山地区断层垂直形变与现今活动特征研究
|
摘要
利用天山地区跨断层定点垂直形变测量资料 ,对断层现今活动的动态过程及空间分布进行了初步研究。结果表明 ,天山地区断层现今活动具有时空不均一性。时间上具有准同步转折及阶段性特点 ,各阶段的活动速率和方式不同。空间上 ,断层活动具有区域差异性。秋立塔格断层活动速率最高 ,北轮台 -辛格尔断层活动速率最低。讨论了断层活动与地震的关系 ,认为 2 0 0 0年底准同步转折与 2 0 0 1年 11月喀拉昆仑山口西 8.1级地震有关。
In this paper,fixed cross-fault vertical defomation data in Tianshan are analysed preliminarily and the time process and space distribution of current fault activity in Tianshan area are studied. The results indicate that the nowadays fault activity in Tianshan region manifests itself with space-time unhomogeneity. In the time domain, the activity of faults has features of a synchro turn in the course of events, and staged, which in every stage the activity speed and mode are different.In the space domain,the activities are unlike in different areas,{e.g.}in Qiulitage fault it is the highest, in Beiluntai-Xinger fault the lowest. The relationship between the fault activity and the earthquakes is discuussed. It is considered that the synchro turn is related to the earthquake {%M%s8.1} in November, 2001 in the west of Kunlun mountain pass.
