BANGKOK — The death toll from a powerful 7.7 magnitude earthquake in Myanmar jumped to more than 1,000 on Saturday as more bodies were pulled from the rubble of the scores of buildings that collapsed when it struck near the country’s second-largest city.

The country’s military-led government said in a statement that 1,002 people have now been found dead and another 2,376 injured, with 30 others missing. The statement suggested the numbers could still rise, saying “detailed figures are still being collected.”

Myanmar is in the throes of a prolonged and bloody civil war, which is already responsible for a massive humanitarian crisis. It makes movement around the country both difficult and dangerous, complicating relief efforts and raising fears that the death toll could still rise precipitously.

The earthquake struck midday Friday with an epicenter not far from Mandalay, followed by several aftershocks including one measuring a strong 6.4 magnitude. It sent buildings in many areas toppling to the ground, buckled roads, caused bridges to collapse and burst a dam.

In neighboring Thailand, the quake rocked the greater Bangkok area, home to some 17 million people — many of whom live in high-rise buildings — and other parts of the country.

Bangkok city authorities said so far six people have been found dead, 26 injured and 47 are still missing, most from a construction site near the capital’s popular Chatuchak market.

When the quake hit, the 33-story high-rise being built by a Chinese firm for the Thai government wobbled, then came crashing to the ground in a massive plume of dust that sent people screaming and fleeing from the scene.

On Saturday, more heavy equipment was brought in to move the tons of rubble, but hope was fading among friends and family members of the missing that they would be found alive.

“I was praying that that they had survived but when I got here and saw the ruin — where could they be? In which corner? Are they still alive? I am still praying that all six are alive,” said 45-year-old Naruemol Thonglek, sobbing as she awaited news about her partner, who is from Myanmar, and five friends who worked at the site.

“I cannot accept this. When I see this I can’t accept this. A close friend of mine is in there, too,” she said.

Waenphet Panta said she hadn’t heard from her daughter Kanlayanee since a phone call about an hour before the quake. A friend told her Kanlayanee had been working high on the building on Friday.

“I am praying my daughter is safe, that she has survived and that she’s at the hospital,” she said, Kanlayanee’s father sitting beside her.

Myanmar sits on a major fault line

Earthquakes are rare in Bangkok, but relatively common in Myanmar. The country sits on the Sagaing Fault, a major north-south fault that separates the India plate and the Sunda plate.

Brian Baptie, a seismologist with the British Geological Survey, said it appears a 200 kilometer (125 mile) section of the fault ruptured for just over a minute, with a slip of up to 5 meters (16.4 feet) in places, causing intense ground shaking in an area where most of the population lives in buildings constructed of timber and unreinforced brick masonry.

“When you have a large earthquake in an area where there are over a million people, many of them living in vulnerable buildings, the consequences can often be disastrous,” he said in a statement.

“From initial reports, that seems likely to be the case here.”

A natural disaster on top of a civil war

Myanmar’s government said blood was in high demand in the hardest-hit areas. In a country where prior governments sometimes have been slow to accept foreign aid, Min Aung Hlaing said Myanmar was ready to accept outside assistance.

Myanmar’s military seized power from the elected government of Aung San Suu Kyi in February 2021, and is now involved in a bloody civil war with long-established militias and newly formed pro-democracy ones.

Government forces have lost control of much of Myanmar, and many places are incredibly dangerous or simply impossible for aid groups to reach. More than 3 million people have been displaced by the fighting and nearly 20 million are in need, according to the United Nations.

“Although a full picture of the damage is still emerging, most of us have never seen such destruction,” said Haider Yaqub, Myanmar country director for the NGO Plan International, from Yangon.

“Without a doubt, the humanitarian needs will be significant.”

Rescue groups head to Myanmar

China and Russia are the largest suppliers of weapons to Myanmar’s military, and were among the first to step in with humanitarian aid.

A 37-member team from the Chinese province of Yunnan reached the city of Yangon early Saturday with earthquake detectors, drones and other supplies, the official Xinhua news agency reported.

Russia’s emergencies ministry dispatched two planes carrying 120 rescuers and supplies, according to a report from the Russian state news agency Tass.

India sent a search and rescue team and a medical team as well as provisions, while Malaysia’s foreign ministry said the country will send 50 people on Sunday to help identify and provide aid to the worst-hit areas.

South Korea announced it would provide $2 million worth of humanitarian aid to Myanmar through international organizations to support recovery efforts. The Foreign Ministry added that Seoul would closely monitor the situation and consider additional support if needed.

The United Nations allocated $5 million to start relief efforts. President Donald Trump said Friday that the U.S. was going to help with the response, but some experts were concerned about this effort given his administration’s deep cuts in foreign assistance.

The Trump administration’s cuts to the United States Agency for International Development have already forced the United Nations and non-governmental organization to cut many programs in Myanmar.
