Fig. 2: 3D deformation field and surface rupture displacements.

a 3D deformation field derived from Sentinel-1 and Sentinel-2 image pixel offsets. From left to right are the north-south, east-west, and vertical components. Black lines denote the inferred surface rupture traces provided by Reitman et al. 54. Surface rupture displacements, both horizontally perpendicular and parallel to the fault strike, along with their uncertainties, are calculated for the M7.8 event (b) and the M7.5 event (c). Distances along the fault are calculated from the westernmost point.
