Rescue efforts continued in eight buildings in western Turkish city of Izmir on Monday, authorities said, as the death toll from Friday's powerful earthquake in the Aegean Sea region rose to 81.
Turkish authorities said 79 were killed, all in Izmir, while two teenagers died on the Greek island of Samos.
More than 3,500 tents and 13,000 beds have been supplied to provide temporary shelter, according to Turkey's Disaster and Emergency Authority (AFAD), which said 962 people had been injured in Friday's earthquake.
More than 740 victims have so far been discharged from hospitals, AFAD said.
Many in Turkey made homeless by the quake also spent a second night outdoors. The emergency authority provided some 1,500 tents and said 2,000 more were on the way. Containers were also being readied. Izmir Mayor Tunc Soyer said the search was also on for blankets and heaters, as temperatures were expected to tumble.
The magnitude-6.6 quake struck on Friday at a depth of 16.5 kilometres in Izmir's Seferihisar district. Marco Bohnhoff, a seismologist with the Geological Research Centre (GFZ) in Potsdam, Germany, said it was a "normal-faulting" quake, which means that part of the subsoil has moved downwards.
He says the magnitude recorded was at the upper end of what is normally expected for such quakes.
It was felt on Greek islands in the Aegean as well as in nearby Turkish cities, including Turkey's largest city, Istanbul, some 540 kilometres to the north. Several buildings collapsed completely, while hundreds were left damaged by the quake.
According to official figures, rescuers were searching for survivors at eight buildings on Sunday. They urged relief workers and bystanders to be quiet so they could hear voices.
Schools in Izmir, Turkey's third-largest city after Istanbul and Ankara with 4.3 million people, would close for the week. Turkish Vice President Fuat Oktay said 26 buildings in Izmir would have to be demolished because they were no longer inhabitable. Sport centres and club houses were being converted into temporary housing.
Turkey sits on major seismic fault lines. Two deadly quakes in the eastern cities of Elazig and Malatya in January killed more than 40 people.
