Geotechnical damages observed in the 2023 Turkey-Syria Earthquake

抄録

Geotechnical damage resulting from the 2023 Turkey-Syria earthquake reported here is summarized as follows: A landslide dam was formed in Islahiye because of the earthquake. In Tepehan, a landslide occurred on a relatively gentle limestone slope, possibly linked to fault movements in the area. Iskenderun experienced building collapses on soft ground, along with building tilts and ground subsidence. These phenomena were caused by the liquefaction of reclaimed coastal land. Golbasi witnessed significant damage due to liquefaction in structures with shallow foundations on soft ground. This damage involved the tilting and settling of buildings. Further investigation is necessary to accurately map the extent of liquefied soil layers in this region. These geotechnical damages underscore the diverse and complex impacts of the earthquake on various soil types and geological conditions across different areas. Comprehensive investigations are crucial for understanding the specific mechanisms and vulnerabilities that led to these damages, as well as for developing strategies to mitigate similar risks in the future.
