摘要
介绍了光学与雷达遥感在地震形变监测中的研究现状及实际应用,基于Landsat-8 OLI影像提取了2013年Mw7.7巴基斯坦阿瓦兰地震的同震形变图,基于Sentinel-1A SAR影像提取了2017年Mw7.4伊拉克-伊朗地震的三维形变场,分析了各自特点与局限性,讨论了联合提取地震形变信息的可行性。光学遥感可为Mw>7 InSAR形变监测提供可靠的辅助观测数据,在联合提取同震三维形变方面具有应用潜力。
Firstly,we introduced the application and research progress of optical remote sensing and radar remote sensing technology in seismic deformation monitoring in this paper.Then we respectively obtained horizontal coseismic deformation field of the Mw7.7 Pakistan Awaran earthquake in 2013 with use Landsat-8 OLI images and three-dimensional deformation field of the Mw7.4 Iraq-Iran earthquake in 2017 with Sentinel-1A SAR images.Finally,the applicability of optical remote sensing images and SAR images for coseismic deformation monitoring,was analyzed,which shows that optical remote sensing can provide reliable auxiliary observation data for the Mw>7 coseismic deformation monitoring.The combination of optical remote sensing and SAR data has great potential in three-dimensional coseismic deformation monitoring.
