Book Part Citation - WoS: 1Citation - Scopus: 1Learning from Damaged Historic Constructions: Recent Earthquakes in Turkey(Springer Science and Business Media B.V., 2026) Kishalı, Emre; Balcı, Esra; Almaç, Umut; Semiz, Nisa; Türer, Ahmet; Kambek, Erkan; Koç, SüheylaIn February 2023, the southeastern region of Turkiye was struck by significant earthquakes along the Eastern Anatolian Fault Zone, resulting in widespread destruction and substantial loss of life. The intense ground movements caused severe damage to the area's architectural heritage, impacting numerous historic buildings that represent a range of periods, functions, scales, construction techniques, and materials. The regions affected by these earthquakes presented a unique opportunity for analysing the damage to cultural assets, a chance that may not present itself again for some time. It is crucial to collect data on the damage sustained by these structures and to leverage this knowledge for their future preservation. The quality of masonry walls in damaged buildings raises important concerns, particularly regarding the bond patterns and the quality of the binding mortar. Damage has also been observed in vaulted monuments. Many of these structures lack tie systems capable of withstanding lateral forces, which would enhance the structural behaviour during earthquakes. Additionally, past restoration efforts warrant attention, particularly in repair interventions such as reintegration; it has been noted that traditional construction practices were often overlooked. The structural relationship between old and new materials was not fully established, and insufficient measures were taken to reinforce this connection, rendering the repairs less effective. The text highlights the evaluation of earthquake damage at the scale of individual structures, with a particular emphasis on damage types associated with restoration practices implemented in the past. This methodology enables the development of appropriate recommendations to address conservation issues. The data used in this study were derived from various projects, particularly those focused on assessing architectural heritage affected by the February 2023 earthquakes, in which the authors were actively engaged.Article Citation - Scopus: 1Düzce Kent Merkezi Zeminlerinin Sıvılaşma Potansiyelinin Değerlendirilmesi(TMMOB - Jeoloji Muhendisleri Odasi jmo@jmo.org.tr, 2019-06-15) Akin, Muge K.Soil liquefaction is one of the ground deformations occurred during an earthquake which may cause serious damages such as settlement and tilting of structures due to loss of bearing capacity of foundations. Düzce and its surrounding settle on a plain which consists of silty and sandy layers with shallow groundwater level. Besides, the North Anatolian Fault Zone is a major seismic source which is capable of producing large magnitude earthquakes. All these data point out that the ground deformations like liquefaction and lateral spreading may occur during a probable large earthquake around Düzce and its close vicinity. In this study, the geotechnical data of 40 boreholes drilled to determine the local ground conditions and the groundwater level in Düzce were considered. Based on the field studies, it was aimed to evaluate the liquefaction potential considering the fact that the groundwater level is shallow as well as the subsurface soil is composed of loose alluvium. Liquefaction Potential Index (LPI) and Liquefaction Severity Index (LSI) methods were taken into account and the liquefaction potential of Düzce province was determined and mapped with respect to various earthquake scenarios in GIS environment. These maps are compared on the basis of different scenarios. Accordingly, it is concluded that the liquefaction potential is high-very high in the south and south-eastern sections of the study area where the construction of new residential buildings progressively continues. © 2019 Elsevier B.V., All rights reserved.
