Structural controls on fault slip models of the 6 February 2023 Kahramanmaraş, Türkiye earthquake doublet with finite element analyses
Original language description
Two major earthquakes of Mw7.8 and Mw7.5 ruptured the Southern East Anatolian Fault (SEAF) and the Savrun-Çardak-Sürgü fault (SCSF), devastating southeast Türkiye and northwest Syria on 6 February 2023. We adopt innovative nonlinear and linear approaches to analyze the coseismic ground displacements and estimate the complex slip geometry. Unlike conventional analytical solutions that simplify crust heterogeneity, finite-element fault models invert the displacement data and simulate the dual-fault geometry with non-uniformly distributed shallow crustal materials. Our results suggest the west-dipping SEAF and north-dipping SCSF accommodate earthquake slips of >10 m. Their respective slip distributions and proximal aftershocks correlate spatially with local seismic velocity anomalies (i.e., ΔVp and ΔVs), which implies differences in structural control along these two faults and provides insights into assessing the seismic hazard of mixed incipient-mature fault systems.
