TRANSCRIPT:
These crews are part of a rescue operation in Myanmar, searching for survivors after a 7.7 magnitude earthquake struck the country.
A 30 year old woman identified as Phyu Lay Khaing is one of the people to have been pulled alive out of the rubble of a collapsed building in Mandalay, near the epicentre of the quake.
But the Red Cross says more than 90 people may still be trapped under the debris of the Sky Villa Condominium, 12 storey apartment block.
Dr Tawseen Visanuyothin is among those working to save lives.
"Once we detect vital signs or manage to reach someone trapped in the rubble, then us, the medical team, step in — to either save lives, assess their condition, or arrange a transfer. We have to act fast because every second counts."
Myanmar’s military junta says at least 1,600 [[1644]] have died in the earthquake, and over 3,400 injured.
So the race is on to find those who survived - with rescue operations intensifying over the weekend.
But the damage is extensive.
Footage posted online shows smoke engulfing the University of Mandalay, while temples, homes, and public buildings lie in ruins.
And several buildings have collapsed since the quake hit.
The damage has not been limited to Myanmar.
A 6.7 magnitude aftershock has been felt across the region from Vietnam and China to as far as Pakistan.
In neighbouring Thailand, tremors reached a magnitude 7.1 in Bangkok, over a thousand kilometres from the epicentre.
It caused a 33-storey building still under construction to collapse, killing at least nine people and leaving more than 100 unaccounted for.
Chanpen Kaewnoi is one of many waiting for news of their loved ones.
"My mother and my sister were working on the 5th floor (of collapsed building), my sister ran back to call out for my mum and both of them together with their co-workers ran down. But seems like my mother tripped and fell, my sister tried to help her up and that's when they couldn't make it out."
Dr Kyi Minn is the national director of World Vision Myanmar.
He has told SBS News says it will take some time to get a full understanding of the extent of the damage across the region.
"Relief activities might be hampered firstly, by the transportation. Because the road from Yangon to Mandalay is severely damaged. And also there is no air transportation. So we have to find out alternative way to get into the affected area. The immediate need is the portable water and the food items. And then later we need the shelter for those who lost their accommodation."
International aid is slowly arriving in Myanmar.
China has pledged over $20 million Australian dollars [[US$13 million]] and sent more than 80 emergency personnel, while India’s first relief shipment has landed.
Some aid organisations the assistance is needed not just because of the scale of the disaster - but because of fears the country's healthcare system and emergency response infrastructure are barely functional.
Su Mon Htay, from Plan International Myanmar, says that Myanmar is severely underprepared after four years of civil conflict since the 2021 military coup.
"In Mandalay it's so desperate. Mandalay is just 12 miles from the epicentre and the damaging of infrastructure, the buildings, the roads cracking, airport tower was just falling and the bridge. And especially the building damage was so severe and people are just you know, so shocked. People are just desperate, devastated and when I see the damage of the bridges and the roads it was so huge. I have never seen anything like that in my life before."
Ms Htay says teams continue their work even as the ground continues to shake.
"And aftershocks are still coming in as well. So people are just so afraid right now. And they're just on the streets, living on the streets, sleeping on the streets, panicking and so fearful. Another huge challenge that we're facing here is the communication interruptions. We're not having access to communications: mobile phones and internet are not working under this unstable situation. We don't have any information right now, and it's a main challenge."
Back in Bangkok, traffic has come to a standstill, with rail systems shut down, roads jammed, and emergency services stretched thin.
Yet despite the chaos, there have been moments of joy.
At a Bangkok hospital, 36-year-old Kanthong Saenmuangshin gave birth as tremors rocked the city.
"I was telling my baby, don't come out yet. But the pain kept growing and growing. Then I was put on a hospital bed and was surrounded by a lot of medical staff where I just gave birth right then and there. It was all a shock to me too. Once my baby was born, the ground stopped shaking. I felt great, I saw my child - and the earthquake stopped. I am so impressed and happy with how the hospital took care of me."
