Architectural Heritage After the February 6th Kahramanmaraş Earthquakes: Preliminary Observations on Historical Masonry Structures

Abstract

On February 6th, 2023, Kahramanmaraş province in Türkiye experienced a powerful earthquake with a magnitude of 7.7 on the Richter scale, followed by another significant earthquake with a magnitude of 7.6. These seismic events resulted in considerable loss of life, injuries, and extensive damage to the region's historical masonry structures. The seismic vulnerability of these structures, stemming from factors such as low strength, inadequate seismic detailing, and limited ductility, contributed to various forms of damage, including cracking, displacement, and, in some cases, complete collapse under the seismic forces. The objective of this study is to provide comprehensive field research results of masonry historical structures situated in various cities within the region impacted by the Kahramanmaraş earthquakes occurred on February 6, 2023. The paper presents the findings of reconnaissance studies, delving into the failure mechanisms observed in masonry historical structures, with specific attention to walls, domes, and minarets. The insights gained from the earthquake damages will be valuable in reducing the likelihood of future earthquake damage to these structures.
