Abstract
We studied the dynamic rupture propagation of the February 6th, 2023 (Mw7.8, 01:17 UTC) Pazarcık (Kahramanmaraş), Turkey, earthquake by incorporating the non-planar fault structure, the regional stress field, and a data-driven friction parameterization into numerical simulations. To explain the rupture extent of 200 km and the average speed, a regional non-uniform load is necessary and was determined from the orientation and intensity of the principal stresses. Careful analysis of near-fault strong motions suggests that the critical slip-weakening distance (D_c) varies smoothly along the fault strike (between 0.6 - 1.2 m) with mean val... more
