Seismic risk assessments in Turkey

Overview

Geology expert Prof. Dr. Osman Bektaş has provided assessments regarding seismic risks in Turkey, focusing on fault line behavior and mapping limitations.

Initially, Bektaş outlined two potential earthquake scenarios for the Marmara Sea region that could impact Istanbul. The first scenario involves a single large rupture on the North Anatolian Fault capable of generating a magnitude-7 or greater earthquake. The second scenario suggests energy might be released more gradually through multiple magnitude-6-plus events and fault creep.

Subsequently, Bektaş cautioned that active fault maps should not be interpreted as definitive guarantees of safety. He noted that many faults remain undiscovered or underwater, and emphasized that a fault does not need to have produced a major earthquake to be considered active and dangerous. Citing the 1968 Bartın earthquake as an example of activity in overlooked areas, he called for continuous scientific updates to fault maps and increased public awareness of seismic risks, particularly along the Black Sea coast.
