Fig. 5: Spatial interrelationships between coseismic slip, afterslip, and aftershock.

Coulomb failure stress change (\(\triangle {{{\rm{CFS}}}}\)) on the seismogenic fault plane of the earthquake doublet caused by a coseismic slip and b afterslip. SQR seismically quiescent region, AS Amanos segment, PS Pazarcık segment, ES Erkenek segment, NF Nurdağı fault, SF Sürgü fault, DF Doğanşehir fault, ÇF Çardak fault, YF Yeşilköy fault. White contours represent our preferred afterslip distribution, with values exceeding 0.1 m. Yellow dots are the relocated aftershocks within 5 km of the fault plane²⁹. \(\triangle {{{\rm{CFS}}}}\) on c the Mw 6.6 06/02/2023 aftershock fault plane and d the Mw 6.3 Antakya fault plane due to the Mw 7.8 Nurdağı-Pazarcık earthquake. e Relocated background seismicity with depth²². The yellow bars represent the number of background seismicity. Average f coseismic slip and g afterslip with depth associated with the Mw 7.8 Nurdağı-Pazarcık earthquake (red line) and the Mw 7.7 Ekinözü earthquake (green line). The orange bars represent the number of aftershocks.
