The earthquake rocked the Mediterranean shortly after 12.45pm (3.45pm local time) and was centred south of the coastal resort town of Antalya. According to the Kandilli Observatory, the quake reached a depth of 58 miles (93.3km) and was felt across neighbouring provinces.
A number of terrified residents in the town of Mahmutlar in Antalya said they felt their homes shaking from the tremors.
Mahmutlar is located 35 miles from the epicentre of the quake and home to around 15,000 people.
At this stage there are no immediate reports of casualties or damage to any buildings.
In a testimony post on the European-Mediterranean Seismological Centre, one resident said: “Just felt it moving sideways in Alanya, Turkey.”
Another said: “Alanya we felt the whole house shaking.”
A third wrote: “The whole building was shaking ...for about 10 sec.”
A fourth added: “The shake was quite noticeable, the chair was slightly shaking under me, as well as the door and furniture and the glassware on the shelf.”
Reports of “medium shakes” were also felt in Morphou bay which is located to the north-western side of the island of Cyprus.
