Rescuers operating in sub-zero temperatures used drills, mechanical diggers and their bare hands to continue the search for survivors at three sites in Elazig province, where the magnitude 6.8 quake struck on Friday evening.
It killed 31 people there and four in the neighboring province of Malatya, and was followed by more than 700 aftershocks, Disaster and Emergency Authority AFAD said on Sunday. More than 1,600 sustained injuries.
Broadcast footage showed a 35-year-old woman and her infant daughter emerging from rubble in the Mustafa Pasa district of Elazig, some 550 km (340 miles) east of the capital Ankara.
Rescuers who heard their screams took several hours to reach them in temperatures as low as -4 degrees Celsius (24.8°F), state media said. The woman’s husband was among those who died.
AFAD said search and rescue operations were still underway at three different sites in Elazig.
Other provinces sent thousands of emergency workers to support rescue efforts, which were also supplemented by hundreds of volunteers, officials said. Tents, beds and blankets were provided to shelter those displaced by the quake.
AFAD urged residents not to return to damaged buildings because of the potential risk of collapse. It said officials had identified 645 heavily damaged and 76 collapsed buildings in the two provinces.
President Tayyip Erdogan said steel-framed houses would be rapidly built in the region to provide housing for displaced residents. Speaking on Saturday during a visit to Elazig and Malatya, he called the quake a test for Turkey.
The country has a history of powerful earthquakes. More than 17,000 people were killed in August 1999 when a 7.6 magnitude quake struck Izmit, a city southeast of Istanbul.
In 2011 a quake in the eastern city of Van killed more than 500.
The death toll from Friday's powerful earthquake in eastern Turkey rose to 31, the country's disaster relief agency said, AzVision.az reports citing Anadolu Agency.
So far, 1,547 people have been reported injured as rescue workers continue recovering victims buried under the rubble, according to the Disaster and Emergency Management Authority (AFAD).
A total of 45 people have been rescued including a woman, 17 hours after her house collapsed.
AFAD said rescue work continues with more than 3,433 personnel with hundreds of vehicles and 17 sniffer dogs in the region.
A team of surveyors is assessing the damage caused by the earthquake, with initial reports suggesting 76 buildings were demolished while 42 damaged and 425 with minor damages.
The 6.8-magnitude quake shook Turkey's Elazig province late Friday. Tremors were also felt in neighboring countries including Syria and Georgia.
More than 530 aftershocks were felt in the region with nine above a 4.0-magnitude.
Earlier Saturday, President Recep Tayyip Erdogan visited the region and attended the funeral of two victims.
"We have borne many earthquakes but the nation has risen above them patiently," said Erdogan, asking citizens to exercise strength in their weakest hour.
Condolences poured in from world over, including from the U.S., Russia, Germany, France, Malaysia and Pakistan.
