Tonga Volcano

Tonga volcano: Eruption more powerful than atomic bomb, Nasa says

The eruption "obliterated" a volcanic island north of the Tongan capital Nuku'alofa, the agency said.

Tonga says more than four-fifths of the population has been affected by the tsunami and falling ash.

Three people were confirmed killed in the tsunami last week.

Before the eruption, the Hunga Tonga-Hunga Ha'apai volcanic island was two separate islands joined by new land formed in 2015.

Nasa says the eruption was so powerful all the new land is gone, along with "large chunks" of the two older islands.

Pacific volcano: New Zealand sends flight to assess Tonga damage

The eruption has covered the Pacific islands in ash, cut power and severed communications.

Up to 80,000 people there could be affected, the International Federation of Red Cross and Red Crescent Societies (IFRC) told the BBC.

New Zealand Prime Minister Jacinda Ardern said the tsunami had wreaked "significant damage".

No deaths have been reported so far.

Information remains scarce, however, and New Zealand and Australia are sending surveillance flights to assess the extent of the damage.

Tonga eruption likely the world's largest in 30 years – scientist

The eruption of the underwater Hunga Tonga-Hunga Haʻapai volcano, about 65km north of Nuku'alofa, on Saturday shot thick ash and steam 20km skywards.

University of Auckland volcanologist Professor Shane Cronin said scenes on the ground would have appeared apocalyptic after the eruption: ash clouds blotting out the sun, thunderclaps of booming shockwaves and thousands of lightening strikes.

Get away from shore - US and Japan warn after Tonga tsunami

The US warned of strong currents and waves, and coastal flooding.

The huge underwater volcanic eruption caused waves of more than a metre to crash into Tonga.

The eruption of the Hunga Tonga-Hunga Haʻapai volcano was heard across the South Pacific, and eventually as far away as the US.

A tsunami warning has been issued for parts of Australia's east coast and Tasmania, and the north and east coast areas of New Zealand's North Island.

Tonga volcano eruption and tsunami: No power, communications still down

A tsunami hit the Kingdom after the volcano erupted for eight minutes, throwing clouds of ash into the sky.

Waves flooded the capital, Nuku'alofa, where video footage has shown water engulfing buildings.

Communications with Tonga has been down since 6.30pm yesterday, with reports that power had been cut in the capital.

Tongan authorities should have a clearer picture this morning of the scale of the damage from Saturday's volcanic eruption and tsunami.

Eruption not affecting Fiji air

The Department of Environment has analysed sulphur dioxide concentration levels over Fiji, and has confirmed that they are below the World Health Organisation's air quality guidelines.

The Department will continue to closely monitor the situation and work with the Fiji National Disaster Management Office and Fiji Meteorological Service.
