Fig. 1: Multi-point seismic model of the 2023 Mw7.8 Kahramanmaraş, Türkiye earthquake.

Space-time moment release is shown by beachballs with radii scaled assuming constant stress drop (i.e., seismic moment to power 1/3) and colored by rupture time relative to the origin time (see the color scale). Focal mechanisms were fixed differently for the SW and NE segments. The major episodes (marked A–F) are detailed in Supplementary Table S1. Star and triangles depict the epicenter and used stations, respectively. The grid of trial sources is shown with small black squares along the faults (blue lines) mapped by Reitman et al.²⁶. Aftershocks located by AFAD are shown as red dots (https://deprem.afad.gov.tr/event-catalog). Yellow rectangle depicts the 2020 Mw 6.8 Elazığ earthquake rupture from the dynamic inversion of Gallovič et al.¹⁷. For a stability assessment of this model, see Supplementary Figs. S2–S4. Inset is the moment-rate function of this 6-subevent model.
