Co-seismic displacements for the 2023 Kahramanmaraş doublet. The Mw 7.6 and Mw 7.8 epicenters are represented with white stars and their associated focal mechanisms³¹. East-West and North-South displacement fields computed with the GDM-OPT-ETQ processing chain applied to Sentinel-2 optical satellite imagery are presented in (a,b). (a) Displays the regional context of the southern part of the EAFZ: the black lines show the database of active faults in the region¹⁵ and the segments of the main and northern strands of the EAFZ are indicated¹⁴. (b) Displays the 48 field measurements (circles) taken in May 2023. The measured offsets along the main fault line are shown in (c), and the regional tectonic context is presented in (d) (active fault of³².
