摘要：利用欧洲航天局最新发射的宽刈幅、高分辨率Sentinel-1A卫星，第一时间获取2016-02-06台湾美浓Mw6．4地震干涉像对，使用D-InSAR技术获取关浓地区的同震形变场。利用震中附近39个同震GPS观测进行对比验证后显示，InSAR获取的同震形变场精度优于1cm（3a）。形变发生在宏观震中30km×30km范围内，主要表现为沿雷达视线向抬升，最大抬升约12cm。从形变场空间分布特征可以看出，空间连续性较好，说明宏观震中附近地表未发生明显破裂。宏观震中并不与震中位置重合，而是位于震中西部约15km处。

英文摘要：

On February 6, 2016, a Mw6.4 earthquake occurred in Meinung district of Kaohsiung city, Taiwan,China. The epicenter area, determined by seismic data, lies in a region bounded by Chaochou and Chishan faults. The co-seismic surface deformation of the region is extracted using Sentinel-lA ra- dar data based on differential interferometry. We get reliable co-seismic displacement fields compared with GPS data. InSAR-derived displacement field shows that there is an uplift zone along line-of-sight of about 30 km diameter, located at about 15 km west of the epicenter with a maximum displacement of about 12 cm. There is no apparent rupture around the macro-epicenter from the spatial distribution of displacement. The InSAR application of determining the macro-epicenter quickly shows the scien- tific significance of relief supplies and rapid assessment after earthquake.
