Fig. 2: Static slip inversion of the observed GNSS data of the 2023 Mw7.8 Kahramanmaraş, Türkiye, earthquake and slip model for the broadband ground-motion modeling.

a Fit of GNSS horizontal displacements from the slip inversion. Gray line shows the trace of the assumed vertical fault. b Preferred slip model from the GNSS inversion. The approximate assignment to the MPS subsources of Fig. 1 is labeled A–F. Vertical solid line denotes the intersection with the splay fault (excluded from our modeling). Dashed line marks the fault kink (see panel a). c Slip distribution obtained by summing slip contributions from all subsources in the HIC model. The subsources are placed randomly following the probability density function obtained by normalizing the slip distribution in panel b to unit integral (see Methods for more details). The main features of the rupture kinematics are schematically shown by the red arrows at the bottom (bilateral rupture propagation at constant velocity from the splay fault intersection with depicted rupture delay added to rupture time RT).
