A High-Resolution Method for Reconstructing Three-Dimensional Curved Fault Geometry and Coseismic Slip: Application to the 2021 Mw 7.4 Maduo Earthquake

The dataset includes processed Sentinel-1 Synthetic Aperture Radar (SAR) observations from ascending track T099A and descending track T106D, including interferometric line-of-sight (LOS) displacement fields and range-offset measurements; an aftershock catalogue; the triangulated three-dimensional non-planar fault model; and the inverted coseismic slip distribution of the 2021 Mw 7.4 Maduo earthquake, China.The original Sentinel-1 SAR data used to generate the geodetic products were acquired from the European Space Agency (ESA) and accessed through ESA and the Alaska Satellite Facility (ASF). Earthquake focal-mechanism information used in the study was obtained from the U.S. Geological Survey (USGS), the Global Centroid Moment Tensor (Global CMT) catalogue, and the China Earthquake Networks Center (CENC). Some of the figures were generated using Generic Mapping Tools (GMT; Wessel et al., 2019).
