利用Sentinel-1A数据、D-InSAR和沿轨干涉技术获取2016年高雄Ms6.7地震三维形变场
3D Displacement Field of 2016 Kaohsiung Ms6.7 Earthquake from D-InSAR and Along-Track Interferometry with Ascending and Descending Sentinel-1A Images
摘要
Abstract
‘Along-track interferometry'method is proposed to obtain along-track displacements from backward and forward interferograms within regions of burst overlap.The azimuth direction displacement component of non-overlap area is measured by interpolation.The experimental results show that the coseismic displacement of the Kaohsiung earthquake is predominantly vertical and east-west direction,and mainly distributes in left and right valves of a blind fault.The left valve uplifts with a maximum vertical displacement of 12 cm,and the right valve drops with a maximum vertical displacement of 8 cm.Meanwhile,they have a displacement westward,to a maximum of up to 6 cm.In addition,the Kaohsiung earthquake has a characteristic of northwest-southeast trend blind fault between the left and right valve.关键词
