Volkswacht Bodensee - Quake kills over 1,400 in Turkey, Syria

The 7.8-magnitude night-time tremor, followed hours later by a slightly smaller one, wiped out entire sections of major Turkish cities in a region filled with millions of people who have fled the civil war in Syria and other conflicts.

The head of Syria's National Earthquake Centre, Raed Ahmed, called it "the biggest earthquake recorded in the history of the centre".

At least 560 people died in rebel and government-controlled parts of Syria, state media and medical sources said.

Another 912 people died in Turkey, according to President Recep Tayyip Erdogan, whose handling of one of the biggest disasters of his two decades in power could prove consequential to his re-election chances in polls due in May.

The initial quake was followed by more than 50 aftershocks, including a 7.5-magnitude tremor that jolted the region in the middle of search and rescue work on Monday afternoon.

AFP reporters and witnesses felt the second jolt as far apart as the Turkish capital Ankara and the Iraqi Kurdistan city of Irbil.

Shocked survivors in Turkey rushed out into the snow-covered streets in their pyjamas, watching rescuers dig through the debris of damaged homes with their hands.

"Seven members of my family are under the debris," Muhittin Orakci, a stunned survivor in Turkey's mostly Kurdish city of Diyarbakir, told AFP.

"My sister and her three children are there. And also her husband, her father-in-law and her mother-in-law."

The rescue was being hampered by a winter blizzard that covered major roads in ice and snow. Officials said the quake made three major airports in the area inoperable, further complicating deliveries of vital aid.

Erdogan conveyed his sympathies and urged national unity, saying "We hope that we will get through this disaster together as soon as possible and with the least damage."

- Collapsed homes in Syria -

The first quake struck at 04:17 am (0117 GMT) at a depth of about 17.9 kilometres (11 miles) near the Turkish city of Gaziantep, which is home to around two million people, the US Geological Survey said.

The Danish geological institute said the quake tremors were felt as far away as Greenland.

Osama Abdel Hamid, a quake survivor Syria, said his family was sleeping the when shaking began.

"I woke up my wife and my children and we ran towards the door," he said. "We opened it and suddenly all the building collapsed."

A spokesman for Syria's civil defence said teams were scrambling to rescue trapped people.

"Many buildings in different cities and villages in northwestern Syria collapsed... Even now, many families are under the rubble," said Ismail Alabdallah.

Ukrainian President Volodymyr Zelensky offered to provide "the necessary assistance" to Turkey, whose combat drones are helping Kyiv fight the Russian invasion.

- 'People under rubble' -

Images on Turkish television showed rescuers digging through rubble across city centres and residential neighbourhoods of almost all the big cities running along the border with Syria.

Some of the heaviest devastation occurred near the quake's epicentre between Kahramanmaras and Gaziantep, where entire city blocks lay in ruins under the gathering snow.

Kahramanmaras Governor Omer Faruk Coskun said it was too early to estimate the death toll because so many buildings were destroyed.

"It is not possible to give the number of dead and injured at the moment because so many buildings have been destroyed," Coskun said. "The damage is serious."

A famous mosque dating back to the 13th century partially collapsed in the province of Maltaya, where a 14-story building with 28 apartments housed 92 people also collapsed.

In other cities, social media posts showed a 2,200-year-old hilltop castle built by Roman armies in Gaziantep lying in ruins, its walls partially turned to rubble.

"We hear voices here -- and over there, too," one rescuer was overheard as saying on NTV television in front of a flattened building in the city of Diyarbakir.

"There may be 200 people under the rubble."

- Power outages -

The Syrian health ministry reported damage across the provinces of Aleppo, Latakia, Hama and Tartus, where Russia is leasing a naval facility.

AFP correspondents in northern Syria said terrified residents ran out of their homes after the ground shook.

Even before the tragedy, buildings in Aleppo, Syria's pre-war commercial hub, often collapsed due to the dilapidated infrastructure, which has suffered from lack of war-time oversight.

Naci Gorur, an earthquake expert with Turkey's Academy of Sciences, urged local officials to immediately check the region's dams for cracks to avert potentially catastrophic flooding.

Officials cut off natural gas and power supplies across the region as a precaution, also closing shools for two weeks.

"The size of the aftershocks, which may continue for days although mostly decreasing in energy, brings a risk of collapse of structures already weakened by the earlier events," David Rothery, an earthquake expert at the Open University in Britain.

"This makes search and rescue efforts dangerous."

Turkey is in one of the world's most active earthquake zones.

Experts have long warned a large quake could devastate Istanbul, a megalopolis of 16 million people filled with rickety homes.

The last 7.8-magnitude tremor shook Turkey in 1939, when 33,000 died in the eastern Erzincan province.
