Key events
In Thailand, there were no immediate reports of casualties and Prime Minister Paetongtarn Shinawatra called an emergency meeting to assess the impact of the quake.
Thailand’s Department of Disaster Prevention said the quake was felt in almost all regions of the country.
The greater Bangkok area is home to more than 17 million people, many of whom live in high-rise apartments.
As we mentioned earlier, the epicenter of the earthquake was in central Myanmar, about 30 miles (50km) east of the city of Monywa.
The AP says that in the capital Naypyitaw, the quake damaged religious shrines, sending parts toppling to the ground, and some homes.
Further reports of damage were not immediately available from Myanmar, which is embroiled in a civil war.
Here are some of the latest images from Thailand:
Strong, shallow earthquake strikes Myanmar and neighbouring Thailand
An earthquake of magnitude 7.7 has struck Myanmar, the United States Geological Survey (USGS) said, causing hundreds of people to pour out of swaying buildings in Bangkok, the capital of neighbouring Thailand 1,400km away.
USGS said the quake on Friday was shallow, at a depth of just 10km (six miles) with the epicentre near the central city of Mandalay, about 50km (30 miles) east of the city of Monywa.
There were no immediate reports of damage from the earthquake in Myanmar, which is in a state of chaos after a coup in 2021.
Startled residents in densely populated central Bangkok poured out of high-rise condominiums and hotels. The greater Bangkok area is home to more than 17 million people, many of whom live in high-rise apartments.
The quake was forceful enough to send water sloshing out of pools, some high up in high-rises, as the tremor shook.
“I heard it and I was sleeping in the house, I ran as far as I could in my pyjamas out of the building,” Duangjai, a resident of popular tourist city Chiang Mai, northern Thailand, told AFP.
