新疆伽师强震群区的InSAR观测研究
|
摘要
利用欧空局提供的ERS1/2SAR数据,结合美国NASA的高精度SRTM数字高程模型DEM,获得了1996~1999年间伽师强震群部分地区的差分干涉图像。结果表明,该地区同期的地震活动及地壳形变主要受东西向和北东东向断层的影响,柯坪断裂带南北两侧块体的差异运动量约为5mm/a(LOS方向),其中1998年8月2日Ms6.0地震和27日Ms6.6地震可能与隐伏断层无关。
On the basis of ERS 1/2 SAR from ESA,the DInSAR interferograms of Jiashi strong earthquake swarm area during 1996-1999 are obtained by combining with high-precision SRTM digital height model-DEM by NASA of America.The results show that the seismic activities and crustal deformation in this area during 1996-1999 were effected by faults of EW and NEE and the motion difference between the southern and northern blocks of the Keping fault was about 5 mm/a(along the LOS trend).However the Jiashi Ms6.0 earthquake on aug.2,1998 and Ms6.6 earthquake on Aug.27 may not be related to buried fault.
