The Tonga Meteorological services says it is unlikely a tsunami will affect Tonga after a 5.4 magnitude earthquake was felt in Tongatapu this morning.
It said the quake was 214 km deep but no further details provided.
However, residents have reported feeling the rattles on Facebook.
It came after a number of quakes reported after the January eruption of Hunga-Tonga Hunga-Ha’apai and the subsequent tidal wave which caused devastation in Tonga and killed people as far away as South America.
The atmospheric shockwave caused by the eruption was felt as far away as the UK.
The caldera of Hunga-Tonga Hunga-Ha’apai is four kilometres wide and drops to a base 850m below sea level. Before the catastrophic eruption, the base was at a depth of about 150m.
The eruption ejected an enormous amount of material, estimated to be at least 6.5 cubic kilometres.
“If all of Tongatapu, the main island of Tonga, was scraped to sea level, it would fill only two-thirds of the caldera,” Professor Shane Cronin from the University of Auckland said.
