..., Turkey was struck by two major earthquakes. The first, with a moment magnitude ( M ) of 7.7, occurred in Pazarcik at 04:17 local time, with a focal depth of 8.6 km. The earthquake’s epicenter was 37.288°N, 37.043°E, which is 40 km northwest of Gaziantep and 33 km southeast of Kahramanmaras. The second...

.... However, in light of advances in remote data and models, the question arises whether field‐based observations of surface rupture remain useful for understanding rupture processes and seismic hazards. We approach this question using a field‐based study of the central 2023 M w 7.8 Pazarcık, Turkey (Türkiye...

... ). A devastating earthquake of M w 7.8 occurred on Turkey-Syria border on 6 February 2023 in the early hours at 4:17 am local time. This is also the largest recorded earthquake in Turkey that claimed more than 43,000 human lives. The epicenter was located at the boundaries of Amanos and Pazarcik segments...

... on the fault in the last century. This relative quiescence was ended on 6 February 2023 by the Pazarcık–Kahramanmaraş earthquake (M w  = 7.7), which resulted in a c . 300 km long multi-segment surface rupture across southeastern Türkey ( Karabacak et al. 2023 ). The Erkenek and Pazarcık segments of the EAF...

Therefore, a better understanding and characterization of pulse properties (e.g. period and amplitude) and their underlying physical factors are crucial for earthquake-resistant design...

As the earthquakes occurred at 04:17 (M w = 7.7, Pazarcık, Kahramanmaraş) and 12:30 (M w = 7.6, Elbistan, Kahramanmaraş) on 6 February 2023, neighbouring active fault systems were broken in succession between the Hatay and Malatya provinces in the region. The first earthquake, one...

Early postseismic deformation within two months exhibits displacement discontinuities in the Amanos and Pazarcık segments and the Çardak fault, suggesting that the afterslip partially compensated the coseismic slip deficit at the shallow depths...

...). We thoroughly investigate the correlation fractal dimension (Dc) formulated upon the scale‐invariant relative clustering in earthquake pattern identification. We provide a comprehensive examination of pre‐ and postseismicity patterns of the M w 7.7 Nurdağı‐Pazarcık, M w 7.6 Ekinözü, and M w 6.7...

Using strong‐motion waveforms recorded during the Kahramanmaraş sequence, we simulate a real‐time playback and calculate how a finite‐source model computed with the Finite‐fault rupture Detector (FinDer) algorithm would evolve for the M w 7.8 Pazarcık, M w 7.6 Elbistan, and M w 6.4 Yayladağı earthquakes...
