A new tsunami warning is now in force for all of Tonga following this evening’s violent eruption of the Hunga-Tonga-Hunga-Ha’apai undersea volcano with tidal waves flooding the shoreline of the capital Nuku’alofa.

Parts of New Zealand and Samoa are also under tsunami warning, reports RNZ News.

The eruption came shortly after locals in Tongatapu reported a “deafening” sound of an eruption this afternoon. They also reported stones pouring down on the main island of Tongatapu.

No injuries or deaths have been reported.

Kaniva News correspondent in Tonga Patimiosi Ngūngūtau shared a photo of sea waves flowing inland.

He described the deafening sound as “weird”.

‘Rain of small black stones’
“It was a rain of small black stones and black ash,” he said.

He said they had evacuated to Liahona in the central south.

Ngūngūtau said ash not only covered vehicle screens but their impact sounded like they could break the screens.

Tonga Geological Services said at 1.45pm this afternoon satellite images captured this morning between showed volcanic eruption continuing, with ash emitted and detected at 7.20am this morning.

“This ash plume was due to an eruption that lasted 10 to 15 minutes and was drifting downwind to the east from Hunga. No further eruption has been detected since then,” it said.

“Near shore water turbulence caused by the eruption is expected to have ceased for all shores of Ha’apai and Tongatapu islands. It is advised that the public observe currents before entering the water.

“Owners of rainwater harvesting systems in all Tonga are advised to check for ashfall on your roofs for ash before reconnecting your guttering systems.

“Please clean if ashfall is evident. For locations of residents where the pungent smell of sulphur or ammonia is experienced please use breathing masks if helpful”.

Flooded coastal roads
RNZ News reports tidal waves crossed the shoreline in Nuku’alofa and flooded coastal roads and properties.

There is panic and people are worried and uncertain what to do, RNZ Pacific reporters said.

The advisory for New Zealand’s north and east coast of the North Island and the Chatham Islands came around 8.45pm from NEMA (National Emergency Management Agency).

It said people in those areas might experience strong and unusual currents and unpredictable surges at the shore.

People are being urged to stay away from beaches and shore areas until 4am tomorrow.

There was no need to evacuate other areas unless directly advised by local civil defence authorities.

Coastal inundation (flooding of land areas near the shore) is not expected as a result of this event.

King evacuated from palace
Kaniva News reports that Tonga’s King Tupou VI has been evacuated from the Royal Palace after the tsunami flooding.

“A convoy of police and troops rushed the king to the villa at Mataki’eua as residents headed for higher ground”, reports Fiji-based Islands Business magazine.

“Earlier, a series if explosions were heard as an undersea volcano erupted throwing clouds of ash into the sky.”

TVNZ 1News reports that the second eruption in as many days had sent ash, steam and gas 20 km into the air.

A journalist based in Nukuʻalofa told the channel the situation was “precarious”.

“You’ll forgive the wobble in my voice because we’ve had a very frightening hour,” she said.

The tsunami marine warning issued for all of Tonga waters following the violent eruptions of underwater volcano Hunga-Tonga-Hunga-Ha’apai has been lifted.

Hunga-Tonga-Hunga-Ha’apai erupted on Friday sending ash, steam and gas 20 kilometres into the air.

The volcano had been active from 20 December 2021 but was declared dormant on  January 11.

The head of Tonga Geological Services, Taaniela Kula, told RNZ Pacific that at 4am on Friday, January 15, an eruption was picked up on satellite.

Kula said the eruption on Friday was almost seven times bigger than the one on December 20, bigger in terms of the radius of the plume that was scattered from the volcano, up to 250km away from the volcano radius.

He said his team visited the site on Friday to see up close, 2-3km away from the volcano, and the eruption of ash really shot up to over 1km into the atmosphere.

“That created an ash column of about 5km diameter just elevating ash up to 20kms into the atmosphere, that was really high, and the plume covered that 5km diameter of that island.”

Kula said it appeared to have been sourced from two locations but “we couldn’t identify on Friday because of too much plume and the source was not clear but his team could see multiple shooting … and ash”.

He said it was the biggest eruption he has seen on the site.

Overnight, Kula said they noted that the lack of ash emerging into the atmosphere and the satellite picked up ash was drifting to the east and dispersed after, around 2am. It had gone past ‘Otu Mu’omu’a islands of Ha’apai to the East side.

“This morning, steam and gas plume coming out of the volcano, drifting Eastwards, and so they have lowered the aviation colour code from ‘Red’ to ‘Orange’ this morning because of no sign of ash.”

Kula said a lot of ash was noticed in the Ha’apai group and this morning a navy boat is shipping out drinking water to locals.

The Tonga Geological Services said people were told to disconnect their water supplies on Friday and to ensure that there was no ashfall on their rainwater harvesting system, especially their roof and also their gutter system before they reconnect it.
