Ankara: Turkey's seismology centre says an earthquake with a preliminary magnitude of 6.2 has hit an area off Turkey's Aegean coast.
The earthquake was felt in Istanbul and neighbouring regions, but there was no immediate report of any damage.
The Istanbul-based Kandilli Observatory says the quake occurred at 4:16 pm (1416 GMT) on Tuesday off the coast from Turkey's northwestern Canakkale province. Authorities are still assessing possible damage.
The Athens Geodynamic Institute in Greece put the magnitude at 5.9 and said the quake occurred between the Greek islands of Lemnos and Lesvos, near the Turkish coast. The quake was also mildly felt in Athens. The US Geological Survey gave a preliminary magnitude of 5.7.
Earthquakes are common in Turkey and Greece, much of which lie atop fault lines.
