The Friday earthquake, strongest Myanmar has recorded in a century, has killed over 1,600 people and left hundreds injured and missing.

Rescuers race against time to find any survivors in ravaged Myanmar after the March 28 powerful 7.7 magnitude earthquake and multiple aftershocks, described as force equivalent to more than "300 atomic bombs".

A 5.1 magnitude earthquake hit near Myanmar's second-largest city on Sunday as well, the USGS said, the latest in a string of aftershocks following Friday's temblor.

The earthquake, strongest Myanmar has recorded in a century, has killed over 1,600 people and left hundreds injured and missing. The earthquake also led to casualties in neighbouring Thailand, where 17 people have died in Bangkok, as per city authorities. A 30-storey under-construction skyscraper in Bangkok collapsed after the Friday earthquake. The Myanmar earthquake, whose epicentre was near Mandalay, was followed by over a dozen aftershocks, according to the US Geological Survey (USGS). USGS data showed that a total 15 earthquakes were recorded in Myanmar within 10 hours on Friday, starting with the massive 7,7 magnitude trembler that struck the country at 06:20:54 (UTC).

The most powerful aftershock was measured at Magnitude 6.7, occurring at 06:32:04 (UTC), according to USGS. On Saturday, March 29, also, Myanmar was hit by at least two earthquakes, with one measuring 5.1 in magnitude, other 4.2, as per USGS.

The earthquake in Myanmar unleashed energy equivalent to “334 atomic bombs,” according to a geologist cited in a CNN report. “The force that a quake like this releases is about 334 atomic bombs,” the report quoted geologist Jess Phoenix...Bottom of Form

While the death toll currently stands at over 1,600 people, the USGS said the highest probability is that more than 10,000 people may have died, according to a Bloomberg report.

USGS warned that estimated economic losses may exceed Myanmar’s gross domestic product.

An initial assessment by Myanmar's opposition NUG cited in a Reuters report said at least 2,900 buildings, 30 roads and seven bridges had been damaged by the earthquake. "Due to significant damage, Naypyitaw and Mandalay international airports are temporarily closed," the report quoted the NUG.

The control tower at the airport in Naypyitaw, Myanmar's purpose-built capital city, also collapsed in the earthquake, making it inoperable, a person with knowledge of the situation told Reuters.
