摘要
基于DORIS软件和欧空局提供的ENVISAT数据,结合美国NASA的高精度SRTM数字高程模型DEM,以二轨差分方法获取了意大利拉奎拉地震同震形变场的差分干涉图。结果表明,该区域在往西南方向上的弧后扩张是此次地震发生的主要驱动力,地震造成了该地区在卫星雷达视线方向上隆起了25.2cm。
According to the principles of D-InSAR, by using Doris and ENVISAT SAR data, two-pass method of D-InSAR is utilized to acquire eoseismic surface deformation images caused by L＇Aquila （Italy） earthquake. Preliminary quantitative cognition was completed based on the D-InSAR interferogram. The results show that the main driving force of the earthquake is the southwest wards and up back-arc spreading of the area and the earth- quake makes the area uplift 25.2 cm in the sight line direction of SAR.
