Tongans flee tsunami following powerful volcanic eruption

Nuku'alofa (Tonga) (AFP) – Frightened Tongans fled to higher ground Saturday after a massive volcanic eruption -- heard in neighbouring countries -- triggered the area's second tsunami in as many days.

"A 1.2 metre tsunami wave has been observed at Nukualofa," Australia's Bureau of Meteorology tweeted. The maximum tsunami wave recorded following Friday's explosion was 30 centimetres.

The latest eruption of the Hunga Tonga-Hunga Ha'apai volcano came just a few hours after Friday's tsunami warning was lifted.

Mere Taufa said she was in her house getting ready for dinner when the volcano erupted.

"It was massive, the ground shook, our house was shaking. It came in waves. My younger brother thought bombs were exploding nearby," Taufa told the Stuff news website.

She said water filled their home minutes later and she saw the wall of a neighbouring house collapse.

"We just knew straight away it was a tsunami. Just water gushing into our home.

"You could just hear screams everywhere, people screaming for safety, for everyone to get to higher ground."

Tonga's King Tupou VI was reported to have been evacuated from the Royal Palace in Nuku'alofa and taken by a police convoy to a villa well away from the coastline.

The initial eruption lasted at least eight minutes and sent plumes of gas, ash and smoke several kilometres into the air. Residents in coastal areas were urged to head for higher ground.

The eruption was so intense it was heard as "loud thunder sounds" in Fiji more than 800 kilometres (500 miles) away, officials in Suva said.

There, officials warned residents to cover water collection tanks in case of acidic ash fall.

Victorina Kioa of the Tonga Public Service Commission said Friday that people should "keep away from areas of warning which are low-lying coastal areas, reefs and beaches".

The head of Tonga Geological Services Taaniela Kula urged people to stay indoors, wear a mask if they were outside and cover rainwater reservoirs and rainwater harvesting systems.

The Pacific Tsunami Warning Centre issued a "tsunami advisory" for American Samoa, saying there was a threat of "sea level fluctuations and strong ocean currents that could be a hazard along beaches".

Similar warnings were issued by authorities in New Zealand and Fiji.

Tsunami hits Tonga after volcanic eruption


A tsunami has flooded Tonga's capital after a large eruption from an undersea volcano. Other Pacific islands have issued advisories and have cautioned residents to seek higher ground.



Tongans were urged to get to higher ground after a massive volcanic eruption triggered a tsunami


The Pacific island of Tonga experienced a large volcanic eruption Saturday followed by a tsunami that flooded parts of the capital, Nuku'alofa.

The surge wave reached a height of 2.7 feet (83 centimeters) in Nuku'alofa, according to the US-based Pacific Tsunami Warning Center. There is no information yet on property damage or casualties.




Images posted on social media from Tonga showed the tsunami breach the shoreline, and move into the town.



The Pacific Tsunami Warning Center said tsunami waves measuring 2 feet in height were observed by sea-level gauges in Pago Pago, the capital of the US territory of American Samoa, around 940 kilometers (580 miles) from Tonga.

Officials there initially issued a tsunami warning and told residents to "immediately" evacuate to higher ground. The warning was lifted shortly thereafter.

Fiji also issued a tsunami warning, telling residents to avoid shorelines "due to strong currents and dangerous waves."

New Zealand, more than 2,000 kilometers away from the site of the eruption, has also issued a tsunami advisory.

New Zealand's National Emergency Management Agency said parts of the country could expect "strong and unusual currents and unpredictable surges at the shore."
Undersea volcano erupts

The eruption Saturday was the latest in a series from the undersea Hunga Tonga, Hunga Ha'apai volcano. Saturday's eruption is the second in only two days.


A previous eruption on Friday sent plumes of ash and smoke into the air, with smoke clouds extending up to 20 kilometers (12 miles) into the atmosphere.


The volcano had some intermittent activity through December last year. On Friday, people were advised by officials to stay home and protect drinking water and resources.

WELLINGTON, New Zealand (AP) — An undersea volcano erupted in spectacular fashion near the Pacific nation of Tonga on Saturday, sending large tsunami waves crashing across the shore and people rushing to higher ground. A tsunami advisory was in effect for Hawaii, Alaska and the U.S. Pacific coast.

There were no immediate reports of injuries or the extent of the damage as communications with the small island nation remained cut off hours after the eruption.

In Hawaii, the Pacific Tsunami Warning Center reported waves slamming ashore from half a meter (a foot) in Nawiliwili, Kauai, to 80 centimeters (2.7 feet) in Hanalei. “We are relieved that there is no reported damage and only minor flooding throughout the islands,” the center said, describing the situation in Hawaii.

On Tonga, video posted to social media showed large waves washing ashore in coastal areas, swirling around homes and buildings.

New Zealand’s military said it was monitoring the situation and remained on standby, ready to assist if asked.

Satellite images showed a huge eruption, a plume of ash, steam and gas rising like a mushroom above the blue Pacific waters.

The Tonga Meteorological Services said a tsunami warning was declared for all of the archipelago, and data from the Pacific tsunami center showed waves of 80 centimeters (2.7 feet) had been detected.

In Hawaii, Alaska and along the U.S. Pacific coast, residents were asked to move away from the coastline to higher ground and pay attention to specific instructions from their local emergency management officials, said Dave Snider, tsunami warning coordinator for the National Tsunami Warning Center in Palmer, Alaska.

“We don’t issue an advisory for this length of coastline as we’ve done — I’m not sure when the last time was — but it really isn’t an everyday experience,” he said. “I hope that elevates the importance and severity for our citizens.”

He said the waves already slamming ashore in Hawaii were just under the criteria for a more serious tsunami warning, with measurements at 80 centimeters (2.7 feet) in Hanalei and Maui. Waves of about 91 centimeters (3 feet) or above would trigger a warning. Snider said they’re currently expecting waves of 30 centimeters (1 foot) to 61 centimeters (2 feet) along the Pacific coast.

Snider said residents in these areas should expect waves and strong and unusual currents for many hours and there could be some low areas that are inundated, such as marinas and harbors.

“The important thing here is the first wave may not be the largest. We could see this play out for several hours,” he added. “It looks like everything will stay below the warning level but it’s difficult to predict because this is a volcanic eruption and we’re set up to measure earthquake or seismic-driven sea waves.”

Residents of American Samoa were alerted of the tsunami warning by local broadcasters as well as church bells that rang territory-wide. An outdoor siren warning system was out of service. Those living along the shoreline quickly moved to higher ground.

As night fell, there were no reports of any damage and the Hawaii-based tsunami center canceled the alert.

Authorities in the nearby island nations of Fiji and Samoa also issued warnings, telling people to avoid the shoreline due to strong currents and dangerous waves. The Japan Meteorological Agency said there may be a slight swelling of the water along the Japanese coasts, but it was not expected to cause any damage.

The Islands Business news site reported that a convoy of police and military troops evacuated Tonga’s King Tupou VI from his palace near the shore. He was among the many residents who headed for higher ground.

The explosion of the Hunga Tonga Hunga Ha’apai volcano was the latest in a series of spectacular eruptions.

A Twitter user identified as Dr. Faka’iloatonga Taumoefolau posted video showing waves crashing ashore.

“Can literally hear the volcano eruption, sounds pretty violent,” he wrote, adding in a later post: “Raining ash and tiny pebbles, darkness blanketing the sky.”

Earlier, the Matangi Tonga news site reported that scientists observed massive explosions, thunder and lightning near the volcano after it started erupting early Friday. Satellite images showed a 5-kilometer (3 mile) -wide plume rising into the air to about 20 kilometers (12 miles).

More than 2,300 kilometers (1,400 miles) away in New Zealand, officials were warning of storm surges from the eruption.

The National Emergency Management Agency said some parts of New Zealand could expect “strong and unusual currents and unpredictable surges at the shore following a large volcanic eruption.”

The volcano is located about 64 kilometers (40 miles) north of the capital, Nuku’alofa. Back in late 2014 and early 2015, a series of eruptions in the area created a small new island and disrupted international air travel to the Pacific archipelago for several days.

Tonga is home to about 105,000 people.
