This is the dramatic moment Myanmar earthquake rescuers battled to save a pregnant woman trapped for three days in a collapsed hotel.

Video shows firefighters and Chinese rescue teams carrying the injured mother out of the ruins of the Great Wall Hotel in Mandalay on March 31.

Authorities said the woman was trapped for nearly 60 hours but was found with stable vital signs. She was reported to be in safe condition following the rescue.

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. More than 2,000 people in the country have been killed and some 4,000, with rescue efforts ongoing.

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. At least 20 people were killed.
