This is the heartwarming moment a family-of-four were rescued after spending six nights trapped in the rubble of their earthquake-ravaged home.

The mother and her three children were buried by the mass of concrete when the quake struck Mandalay, Myanmar, on March 28.

They survived on the meagre supplies they could find in the debris while calling for help. Rescue teams finally cut through the twisted mass of concrete and steel before helping them to safety on April 3.

Volunteer Ang Ko said: 'The relatives were all taken to a hospital. They were relieved they were finally found. It is a miracle they survived.'

The US Geological Survey said the magnitude 7.7 tremor struck at a depth of 10 kilometres (six miles), and was centred in Myanmar, around 50 kilometres (30 miles) east of Monywa, along the Sagaing fault.

Residents ran from their homes when they felt the tremors shortly after 1:20 pm local time on March 28. More than 3,145 people in the country have been killed and some 4,589 injured, with the figures expected to rise.

The quake destroyed buildings, bridges, and dams, leaving many areas in ruins. Communication remains difficult as mobile networks are down, and access to electricity and the internet is limited.

Rescue teams from Communist China - a close ally of the Burmese junta - have been working alongside locals in Myanmar, or Burma, to provide relief from the disaster.

American teams have been delayed by issues with sanctions on the war-torn country and problems obtaining visas.

US officials are said to have claimed that the American absence shows how President Donald Trump's moves to slash the size of the US government have reduced its ability to act during disasters.

In neighbouring Thailand, high-rise buildings shook and an apartment block under construction collapsed in Bangkok. The Bangkok Metropolitan Administration said at least 22 people were killed.
