The powerful tremor came approximately 30 minutes after a smaller earthquake measuring 3.9 magnitude had already unsettled the eastern Thrace region, with tremors felt in parts of Istanbul.
The earlier earthquake occurred in the Sea of Marmara, between Istanbul and Tekirdağ, with AFAD reporting a focal depth of 6.9 kilometres. The Kandilli Observatory alternatively measured this preliminary tremor at magnitude 4.0.
No immediate reports of casualties or significant damage were available.
