摘要/Abstract

摘要： 帕米尔构造结断裂发育,强震频繁,一直是大陆动力学研究关注的重点区域。位于帕米尔内部的公格尔拉张系是中、东帕米尔内部最重要的张性断层之一,对其现今构造形变进行研究,对于探讨帕米尔内部的现今变形状态、动力学机制、强震活动及灾害防御都具有重要意义。本文处理了2018—2022年2个轨道的Sentinel-1 SAR数据,获取了研究区高密度三维形变速率场,并结合库伦应力讨论了研究区地震危险性。结果表明,在东西方向上,公格尔拉张系的木吉断裂存在约10 mm/a的右旋走滑,昆盖山南麓断裂和公格尔山断裂的拉张速率分别约为11和5 mm/a,慕士塔格断裂几乎不作拉张运动;垂直方向上,木吉断层南盘抬升7 mm/a,北盘抬升3 mm/a,昆盖山南麓断裂、公格尔山断裂和慕士塔格断裂的两侧均存在一定程度的抬升,约为3 mm/a;静态库伦应力表示,公格尔拉张系北段为未来强震的危险区。

Abstract: The Pamir Syntaxis is characterized by frequent strong earthquakes and has been a key area of interest in continental dynamics research. The Kongur tension system located within the Pamir is one of the most important tensional faults within the central and eastern Pamir. Studying its current tectonic deformation is of great significance for exploring the current deformation state,dynamic mechanism, strong earthquake activity and disaster prevention in the Pamir. This paper processed Sentinel-1 SAR data from two orbits during the period from 2018 to 2022, obtained a high-density 3D deformation rate field in the study area, and discussed the seismic hazard in the study area in combination with Coulomb stress. The results show that in the east-west direction, the Muji Fault had a dextral strike-slip of 10 and the Kungai Shan South Fault and the Kongur Shan Fault had a tensile rate of 11 mm/a and 5 mm/a, respectively. The Mushtag Fault almost did not undergo tensile movement; vertically, the south wall of the Muji fault rose by 7 mm/a and the north wall rose by 3 mm/a. Both sides of the Kungai Shan South Fault, the Kongur Shan Fault, and the Mushtag Fault had a certain degree of uplift, about 3 mm/a; static Coulomb stress indicated that the northern section of the Kongur tension system is a dangerous area for future strong earthquakes.
