This repo contains notebooks for the 3D co-seismic deformation of the 2021 Mw 7.4 Maduo earthquake in Qinghai, China (USGS) from Sentinel-1 SAR data. It's used in the following paper:

  • Xu, L., Yunjun, Z., Ji, C., Meng, L., Fielding, E. J., Zinke, R., & Bao, H. (2023). Understanding the rupture kinematics and slip model of the 2021 Mw 7.4 Maduo earthquake: A bilateral event on bifurcating faults. Journal of Geophysical Research: Solid Earth, 128(4), e2022JB025936, doi:10.1029/2022JB025936.

Data (Zenodo)

Two pairs of Sentinel-1 SLCs (from ascending track 99 and descending track 106; both acquired at 20 - 26 May 2021) are used to derive the deformation in range and azimuth directions, using both InSAR and SAR speckle tracking techniques.
