This is the terrifying moment an apartment block collapsed during the earthquake in Myanmar.

Footage shows the 12-storey Sky Villa Condominium crumbling as the magnitude 7.7 quake shook Mandalay on March 28.

Onlookers screamed as windows gave way and fell the ground. The building's foundation soon gave way, blanketing the street in a cloud of dust and the rubble plunged to earth.

The condo was built in 2017, and was seen as a sign of Mandalay's rapid urbanisation despite the ongoing civil war in the country.

The US Geological Survey said the 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 2,700 people in the country have been killed and some 4,500 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.

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 in Bangkok.
