Data underlaying the research on a conjugated structure in eastern Taiwan during 2022 GuangFu earthquake

We processed the coseismic LOS results from Sentinel-1 and ALOS-2 satellites via using DInSAR technique during 2022 Guangfu earthquake event. Based on the geological setting and DInSAR constraining, we provided a 3D simulation of coseismic surface deformation from dislocation model in this earthquake event to explain the interaction between two fault systems in eastern Taiwan via a conjugated structure.

本研究针对2022年光复地震事件，采用差分合成孔径雷达干涉测量（Differential Interferometric Synthetic Aperture Radar，DInSAR）技术，处理了Sentinel-1与ALOS-2卫星获取的同震视线向（line-of-sight, LOS）观测结果。基于区域地质背景与DInSAR观测约束，本研究通过位错模型构建了本次地震的同震地表形变三维模拟，以阐明中国台湾东部双断裂体系通过共轭构造相互作用的动力学机制。
