Numerical Analysis of Buildings in Golbasi During the 2023 Turkey-Syria Earthquake
(International Association for Earthquake Engineering, 2024) Tobita, T.; Kunisawa, M.; Sendir Torisu, S.; Kiyota, T.; Tönük, G.; Çinicioğlu, O.; Shiga, M.
On February 6, 2023, earthquakes of Mw 7.8 and Mw 7.5 occurred in south-eastern Turkey. In Golbasi, located on the East Anatolian Fault, severe damages such as building subsidence and tilting due to liquefaction were observed. In this study, settlement and tilting behavior due to liquefaction of relatively large structures in Golbasi, when adjacent to each other, were reproduced using effective stress analysis. The research results demonstrates that the differential subsidence behavior of adjacent buildings can be replicated. Furthermore, the interference of stresses within the soil beneath adjacent structures resulted in behaviors such as inward collapsing or conversely an outward leaning differential subsidence. This study also discusses the subsidence trends associated with varying distances between structures and varying in the embedment depth of shallow foundations. © 2024, International Association for Earthquake Engineering.

Reconnaissance and Discussion on Ground Motion Induced by the 2023 Türkiye-Syria Earthquake
(Taylor and Francis Ltd., 2025) Towhata, I.; Çağlayan, P.Ö.; Tönük, G.; Erginağ, U.C.; Sendir Torisu, S.
This paper discusses the output from the damage reconnaissance conducted after the 2023 Türkiye-Syria earthquake. First, a large landslide occurred in a limestone gentle slope without much ground water. Second, the ground subsidence in the coastal area does not comply the the local soil conditions and other observed post-seismic situations. Third, the acceleration records exhibit stronger motion with longer period and shorter duration towards the western end of the causative fault and suggest supershear rupture. To understand these features of the ground motion, this paper proposes a hypothetical model that can reproduce these observations to a good extent. © 2025 Taylor & Francis Group, LLC.
