【摘要】 采用欧洲太空局提供的ERS1/2 SAR影像数据,结合美国NASA提供的免费SRTM DEM,利用两轨法D-InSAR技术获取了1997年11月8日西藏玛尼地震的部分差分干涉图。结果表明,断裂为左旋扭动态势,由地震引起的雷达视线向的形变北盘约为0.7 m,南盘约为0.8 m,认为,利用D-InSAR技术提取地震形变具有一定的潜力和优势。更多还原

【Abstract】 Based on ERS1/2 SAR image data from European Space Agency as well as the free SRTM DEM from NASA,some differential interference maps of the Nov.8,1997 Mani earthquake are worked out by using two-rail D-InSAR technique.The result shows that rupture is left-lateral,the deformations,caused by the earthquake,of the northern side and southern side of the fault being about 0.7 m and 0.8 m respectively along line of sight of radar.This example indicates that D-InSAR is a potential tool in detecting deformation of an earthquake.更多还原
