Soe Lwin, in Yangon, Myanmar's largest city, said he felt the earthquake for a “long time”.

However, he said there doesn’t appear to be widespread damage in the downtown area of the former capital.

He added that residents are worried about the potential for another, bigger earthquake in the coming days.

We can bring you some images now from Naypyidaw, the capital of Myanmar.

As we mentioned in an earlier post, accessing information from Myanmar is difficult - we're working to find out more.

Just 12 minutes after the first earthquake hit Myanmar, another one struck, according to the US Geological Survey.

The second was a magnitude of 6.4, it records, less than the earlier one of 7.7.

The epicentre was 18km (11.1 miles) south of Sagaing.

Forty-three construction workers are missing after the earthquake caused an unfinished 30-storey building in Bangkok to collapse, Thai authorities say.

Fifty people were inside the building near Chatuchak Park, which is hundreds of miles away from the earthquake's epicentre in Myanmar.

Seven escaped while 43 others remain trapped, the National Institute for Emergency Medicine said in a Facebook post.

AFP news agency also reported that 43 people are missing, quoting police.

"When I arrived to inspect the site, I heard people calling for help, saying help me," Worapat Sukthai, deputy police chief of Bang Sue district, told AFP.

The building was intended for government offices.

Tremors from the earthquake in central Myanmar travelled as far as Bangkok in neighbouring Thailand.

In the Thai capital, rescuers are searching the rubble after a large building collapsed.

Myanmar has been ruled by a military junta since a coup in 2021, making access to information difficult. The state controls almost all of local radio, television, print and online media.

Internet use is also restricted.

Communication lines also appear to be down as the BBC has been unable to get through to aid agencies on the ground.

We have monitored unverified video from Mandalay airport in Myanmar, apparently taken shortly after the powerful earthquake struck.

It showed people screaming and crouched on the ground of the tarmac, with a jetliner in the background.

Voices can be heard saying: "Sit down! Don't run!"

The BBC is working to gather information from Myanmar and verify footage shared online.

The earthquake

• A powerful 7.7 magnitude earthquake has struck central Myanmar, according to the US Geological Survey
• The epicentre was 16km (10 miles) north-west of the city of Sagaing, at a depth of 10km, the USGS says
• Strong tremors were felt hundreds of miles away in Thailand and south-west China

The damage

• Buildings have been damaged in Bangkok, and roads have buckled in Myanmar’s capital, Naypyidaw
• Buildings in Bangkok aren’t usually designed to withstand earthquakes, so the damage could be significant

Government response

• The Thai government is holding an emergency meeting

We're working to gather more information from Myanmar, so stay with us for the latest updates.

Bui Thu, a BBC journalist who lives in Bangkok, tells the BBC World Service’s Newsday programme that she was at home cooking when the initial quake happened.

“I was very nervous, I was very panicked,” she says. “I didn’t know what it was because it has been, I think a decade since Bangkok had a really strong or powerful earthquake like this."

“In my apartment I just see some cracking on the walls and water splashed out of swimming pools and people just yelling.”

Following an aftershock, she, along with a lot of other people, ran out into the street.

“We were just trying to wrap our heads around what’s going on," she says.

“Buildings in Bangkok are not engineered for earthquakes, so I think that’s why I think there’s going to be big damage.”

Earthquakes are relatively more common in Myanmar, compared to Thailand.

Between 1930 and 1956, there where six strong quakes of 7.0 magnitude near the Sagaing Fault, which runs through the centre of the country, AFP news agency reports, citing the USGS.

Thailand is not an earthquake zone and nearly all earthquakes that are felt there, which are rare, are in neighbouring Myanmar.

As buildings in Bangkok are not engineered for powerful earthquakes, the structural damage could be significant.

We've just heard from our team on the ground in Bangkok.

They say they felt buildings swaying and saw people evacuating to the streets.

The shaking was dizzying, they say, and from a window they could see water from the top floor of a skyscraper spilling onto the street.

Stay with us as we gather more information.

In the Thai capital of Bangkok, water can be seen splashing out of a rooftop pool, hitting dozens of floors before falling on to the streets below.

The government in Thailand are holding an emergency meeting.

According to USGS, the earthquake's epicentre was located 16km (10miles) northwest of the Burmese city of Sagaing, near the city Mandalay. This is an area about 100km north of the capital Naypyidaw.

AFP journalists in Naypyidaw said roads were buckled by the force of the tremors and chunks fell from ceilings.

A 7.7 magnitude earthquake has struck Myanmar, the United States Geological Survey (USGS) says.

The tremors were felt in China and Thailand, with footage on social media showing people evacuating buildings in Bangkok and gathering in the streets.
