3D interseismic InSAR velocities for the Yushu–Ganzi–Xianshuihe fault system (YGXFS)

These 3D interseismic InSAR velocity results (E.grd, N.grd, and U.grd) are derived from Sentinel-1 data spanning the 2014–2024 period, comprising five ascending and six descending tracks. We estimated the ascending and descending Line-of-Sight (LOS) velocity fields using a phase gradient based Small Baseline Subsets method. The 2-D horizontal and 1-D vertical velocity components were then decomposed from these LOS velocities, incorporating the interpolated velocity azimuth angle as an additional constraint [Ma et al., 2026]. Coupling_3d.gmt is our 3D fault coupling ratio, referenced to a local Cartesian coordinate system with its origin at (99.44°E, 31.79°N). If you used our results, please cite the following references.
