Simulation of large earthquake synchronization and implications on North Anatolian fault zone Sopacı, E.; Özacar, Atilla Arda (2025-11-25) The North Anatolian Fault (NAF) zone has consistently exhibited a sequence of westward-migrating earthquakes with magnitudes exceeding 7 (Mw>7) during its last three seismic cycles. To investigate the mechanisms underlying...
Modeling Path Effects Due to 3D Velocity Structure for Nonergodic Ground-Motion Models: A Case Study Using Turkish Ground-Motion Data Liu, Chenying; Macedo, Jorge; Abrahamson, Norman; Lacour, Maxime; Gülerce, Zeynep; Kottke, Albert; Özacar, Atilla Arda (2025-04-01) The objective of this study is to assess the performance of different path-effect models for developing nonergodic ground motion models (GMMs) using a Turkish ground-motion database. The cell-specific attenuation approach ...
Intensity Characteristics of Seismograms Recorded During the February 6, 2023, M7.8 TurkiyeKahramanmaras-Pazarcık Earthquake Çetin, Kemal Önder; Elsaid, Alaa; Özacar, Atilla Arda (2025-03-01) The strong ground motion intensity levels recorded during the February 6, 2023, T & uuml;rkiyeKahramanmara & scedil;-Pazarc & imath;k earthquake (M7.8) were compared with the ones predicted by the four ground motion models...
Estimating Systematic Source, Site, and Path Effects in Nonergodic Ground-Motion Models: Insights from the Turkish Ground-Motion Database Liu, Chenying; Macedo, Jorge; Gülerce, Zeynep; Abrahamson, Norman; Kottke, Albert; Akbas, Burak; Onder, Fatih M.; Özacar, Atilla Arda (2024-12-01) The development of ground-motion models (GMMs) is transitioning from ergodic to non-ergodic approaches, which account for spatially varying and systematic source, site, and path effects. This study uses a robust ground-mot...
Implications of Activity Rate Characterization and Fault-Based Partitioning on Probabilistic Seismic Hazard Assessment: A Case Study of Extensional Tectonic Regime in Western Anatolia, Türkiye Shah, Syed Tanvir; Özacar, Atilla Arda; Gülerce, Zeynep (2024-12-01) Complex fault geometries with multiple sets of inclined active faults pose a challenge to the accurate representation of fault-based seismic sources in probabilistic seismic hazard assessment (PSHA). In the absence of slip...
Intensity Characteristics of Seismograms Recorded During the February 6, 2023, M7.8 Türkiye Kahramanmaraş Pazarcik Earthquake * Çetin, Kemal Önder; Elsaid, Alaa; Özacar, Atilla Arda (2024-09-01) The strong ground motion intensity levels recorded during the February 6, 2023, Türkiye- Kahramanmaraş-Pazarcık earthquake (M7.8) were compared with the ones predicted by the four ground motion models of 2014 NGA WEST-2 Gr...
The Seismic Expression and Tectonomagmatic Evolution of Subduction Termination along the Anatolian Margin Delph, Jonathan R.; Reid, Mary; Portner, Daniel E; Beck, Susan L.; Özacar, Atilla Arda; Schleiffarth, ‪W. Kirk; Darin, Mike; Whitney, Donna L.; Cosca, Michael; Teyssier, Christian; KAYMAKCI, NURETDİN; Sandvol, Eric (2024-04-14)
A Novel VS30 Prediction Strategy Taking Fluid Saturation into Account and a New VS30 Model of Türkiye Okay, Hakan Bora; Özacar, Atilla Arda (2024-04-01) The averaged shear-wave velocity of the top 30 m (VS30) is widely used in earthquake engineering as a proxy to represent site responses. However, the spatial availability of measured VS30 is rather limited, and, so far, a ...
