    "abstract": "This data set contains strain, motion magnitude, 3D displacements, and surface slip distributions from the 2023 February Türkiye Earthquakes. COMET presents 0.001 degree (~100 m) resolution 3D displacement fields, with associated uncertainties, jointly inverted from 4 tracks of Sentinel-1 range and azimuth offsets and a set of north and east displacements from Sentinel-2 pixel tracking. From the 3D displacement fields, we calculate 0.001-degree resolution horizontal motion magnitudes, from which we extract surface slip distribution along the two faults ruptured during the Mw7.8 and Mw7.5 earthquakes. Further calculation of a 0.01-degree resolution strain field from the east and north displacement fields highlights the surface ruptures caused by the two earthquakes.",
