Aftershock distribution and moment tensor solutions along the Narlı fault and Pazarcık segment. (a) The aftershocks are represented by black circles and scaled by their magnitudes. The green circles indicate the seismic activity during the interseismic period. The blue solid lines represent the active faults in the study region (Emre et al., 2013). The colored squares indicate the surface offset of the 2023 Mw 7.8 Kahramanmaraş earthquake (Karabulut et al., 2023). The earthquakes are projected onto the profiles indicated by the corresponding black solid lines. The red focal mechanism plots represent the moment tensor inversions of the earthquakes with Mw 3.5+. ID number of each solution is near the focal mechanism plot, and the source parameters are presented in Table S1. The source mechanisms of the 9 September 2012 Mw 5.1 earthquake is demonstrated by green focal mechanism plot (Karabulut et al., 2023). The green and yellow stars show the epicenters of the 2023 and 2012 earthquakes, respectively. The highlighted pink curves indicate the surface offsets obtained at the field (MTA, 2023).

(a) Fault map with surface ruptures of the 2023 Turkey earthquake sequence. Focal mechanisms are from the U.S. Geological Survey (USGS; Goldberg et al., 2023). Shaded areas show the inferred extent of historic surface ruptures labeled by year and magnitude (Duman and Emre, 2013). Red and blue numbers correspond to fault segments modeled in this study named following Duman and Emre (2013). The first earthquake is modeled using six segments of the EAF: 1 and 2, Amanos segment; 3, Pazarcık segment; 4, Nurdağı‐Pazarcık fault (NPF); 5, unnamed Erkenek splay; 6, Erkenek segment. The second earthquake ruptures four segments of the SCSF: 7, Çardak fault; 8, Göksun bend segment; 9, Malatya fault; and 10, unnamed Göksun splay. The Sürgü fault (segment 11) is shown in Figure 5. Inset shows regional tectonic map modified from Barbot and Weiss (2021). Yellow circles show earthquakes of Mw>3.0 before 2021 (European‐Mediterranean Seismological Centre [EMSC] catalog).

(b) Bottom: zoomed view of East Anatolian fault zone principal strain rate directions in purple (first component) and pink (second component) from Weiss et al. (2020). In dark and light gray, we show the seismologically inferred maximum and minimum principal horizontal stress components from Güvercin et al. (2022), as well as in dark and light blue, the maximum and minimum principal horizontal stress orientations used in this study. (c) Initial conditions for 3D dynamic rupture modeling of both large earthquakes. SHmax[°] is the orientation of the maximum horizontal compressive stress from a new stress inversion we perform (based on Güvercin et al., 2022, Fig. S5), Dc is the critical slip‐weakening distance in the linear slip‐weakening friction law, R0 is the maximum relative prestress ratio, and R<R0 is the fault‐local relative prestress ratio modulated by varying fault geometry and orientation. Although the assumed SHmax is the same in distinction to the dynamic rupture models in Jia et al. (2023), no additional smaller scale initial prestress or fault strength heterogeneity is prescribed.
