An earthquake with a magnitude of 5.1 struck near the town of Çanakkale on the western coast of Turkey on Wednesday, the US Geological Survey (USGS) said.
The quake struck some 20 kilometers (about 12 miles) south of Çanakkale near Ayvacık, the USGS said. There were no reports of casualties or material damage.
The tremor was felt all across the country’s west, including in Turkey’s most populous city of İstanbul and the third largest, İzmir.
Çanakkale Mayor Ülgür Gökhan said the earthquake lasted about 45 seconds.
Turkish authorities warned residents in the region not to spend the night indoors if their buildings are damaged or poorly constructed on fears that they could be destroyed by possible aftershocks.
Earthquakes are common in Turkey, which sits on top of active fault lines.
