Fig. 1: Map view of the 2023 Türkiye earthquake doublet.

The stars denote the epicenters. The rectangles and beach balls show the surface projections and mechanisms of the fault segments, respectively (Supplementary Table 1). The green lines represent active faults81, the gray dots represent relocated aftershocks50, and the white diamonds represent surface rupture locations82. Blue to red background shows the coseismic offsets measured from the descending track D21 of the Sentinel-1 satellite. The upper-left inset shows the regional tectonics, while the bottom-right inset displays the misfit curve varying with the average rupture velocity in the joint inversions of sub-fault moment tensors. The base map is created using GMT software102.
