A MAGNITUDE 6.2 earthquake has struck about 136.1 miles northwest of Pangai, Tonga.
The earthquake was at a depth of 14.5 km, the USGS said.
It comes just weeks after tremors destroyed homes – and a tsunami killed a British animal charity worker.
Satellite photographs show once lush green parts of Tonga turned brown and houses flattened.
The government of Tonga described the nation as suffering an “unprecedented disaster”.
New Zealand air force images also show areas blanketed with ash and damaged buildings.
Tongan diplomat Curtis Tu’ihalangingie described the damage as “alarming” and said he feared more deaths.
“Possibly there will be more deaths and we just pray that is not the case,” he said.
Video has also emerged showing the powerful tsunami waves washing ashore, tearing down fences as people flee for their lives.

It comes as the body of the missing British charity worker Angela Glover, 50, was discovered by her husband James.

The volcano which last erupted in 2014, has also caused damage to the islands of Uoleva and Nomuka.
Early data suggests the eruption was the biggest since Mount Pinatubo in the Philippines 30 years ago, New Zealand-based volcanologist Shane Cronin told Radio New Zealand.
DEATH TOLL FEARS
“Further volcanic activity cannot be ruled out,” the U.N. Office for the Coordination of Humanitarian Affairs (OCHA) said in the update today.
It added that the official assessments have not been released yet as the communications have been badly hit.
