An underwater volcano that erupted in Tonga was a ‘massive explosion’ that only happens ‘roughly every thousand years’ and was so large it was visible from space.
The explosion triggered a 7.4-magnitude earthquake and sent tsunami waves crashing into the coast of the Pacific island, leaving it covered in ash and cut off from aid.
In the US, waves of more than four feet were recorded on the California coast on Saturday, and tsunami-effect waves were recorded along the coast in Oregon, Washington, British Columbia in Canada, and Alaska.
Satellite images showed the spectacular eruption from space and despite the dire warnings, spectators flocked to the beaches to view the surging tsunami waves, while surfers threw caution to the wind to catch the powerful waves generated by the surge.
Tsunami-hit Tonga remained largely uncontactable on Sunday with telephone and internet links severed, leaving relatives in faraway New Zealand praying for their families on the Pacific islands as casualty reports had yet to come through.
Professor Shane Cronin, from the University of Auckland, is an expert in Tonga eruptions. ‘This is one of the massive explosions the volcano is capable of producing roughly every thousand years,’ he wrote in The Conversation.
Prof Cronin added: ‘We could be in for several weeks or even years of major volcanic unrest from the Hunga-Tonga-Hunga-Ha’apai volcano.’
Two women drowned in northern Peru when two metre waves hit a truck, dragging it into the sea at Naylamp beach, Lambayeque, in the north of the country.
The driver escaped but his wife and another women drowned in the swell. Although Peru did not issue a tsunami warning, its navy are monitoring ‘abnormal waves’ off its coast.
The massive ash cloud covering the tiny island nation of Tonga is preventing surveillance flights from New Zealand to assess the extent of damage.
New Zealand Prime Minister Jacinda Ardern said the eruption was ‘hugely concerning’ and agencies were still trying to establish full communications with Tonga.
One complicating factor to any international aid effort is that Tonga has so far managed to avoid any outbreaks of Covid-19.
Ms Ardern said New Zealand’s military staff were all fully vaccinated and willing to follow any protocols established by Tonga.
The immediate concern in Tonga is for air and water safety due to ash and smoke. The government has asked the public to wear masks and use bottled water for now. .
Tsunami advisories were issued for Hawaii, Alaska and the U.S. Pacific coast. Hundreds of thousands of Japanese citizens were also advised to evacuate as waves of more than a metre hit coastal areas.
The U.S. Geological Survey estimated the eruption caused the equivalent of magnitude 5.8 earthquake. Scientists said tsunamis generated by volcanoes rather than earthquakes are relatively rare.
The powerful waves registered in Japan, New Zealand and Australia, with a thunderous roar heard 6,000 miles away in Alaska.
The eruption has reportedly created a new island in Tonga, the second time such an event has happened in Tonga in ten years.

Can volcanoes create new islands?
Volcanic islands are created by eruptions underwater, usually at the boundaries of two tectonic plates, which are pieces of the earth’s crust.
When the plates ease apart, lava spews out in a volcanic eruption.
When the lava cools, layers of erupted material form the basis of new land mass.
The Tonga Meteorological Services said a tsunami warning was declared for all of the archipelago, and data from the Pacific tsunami center said waves of 2.7 feet were detected.
Rachel Afeaki-Taumoepeau, who chairs the New Zealand Tonga Business Council, said she hoped the relatively low level of the tsunami waves would have allowed most people to get to safety, although she worried about those living on islands closest to the volcano.
She said she hadn’t yet been able to contact her friends and family in Tonga.
Some churches in New Zealand organised community prayers in Auckland and other cities.
‘We pray God will help our country at this sad moment. We hope everybody is safe,’ Maikeli Atiola, the Secretary of the Wesleyan Church of Tonga in Auckland said, Radio New Zealand reported.
Ardern said the main undersea communications cable has been impacted, likely due to loss of power.
Power was being restored in some areas on the islands and local mobile phones were slowly starting to work, she added.
Official damage assessments were not yet available, she said. But Ardern said the New Zealand high commission in Nuku’alofa had said the tsunami has damaged boats, shops and other infrastructure.
Australia said it will send a P8 surveillance aircraft to Tonga on Monday to assess damage to critical infrastructure such as roads, ports and power lines, which will determine the next phase of the response effort.
In the United States, Secretary of State Antony Blinken said the country stands prepared to provide support.
He said he was ‘deeply concerned for the people of Tonga as they recover from the aftermath of a volcanic eruption and tsunami’. Satellites show volcanic eruption that triggered tsunami advisor

The Hunga-Tonga-Hunga-Ha’apai volcano has erupted regularly over the past few decades but Saturday’s eruption was so loud that residents parts of faraway Fiji and New Zealand said they heard it.
‘My entire house was shaking,’ said Sanya Ruggiero, a Consulting Communications Advisor based in Suva, the capital of Fiji, some 750 kms from Tonga.
‘My doors, windows were all rattling like hell. And mine was not even as bad as others. Hundreds of people ran out of their homes,’ said Ruggiero, who consults for several agencies including the United Nations.
Rumblings and eruptions from the volcano continued to be heard through the night, Ruggiero said. Hundreds of people were moved to evacuation centres in Suva. Fiji Airways had to cancel all its flights due to the ash clouds.
‘This is the worst disaster Tonga has had in living memory and the recovery from this is going to take years,’ Ruggiero said.
Experts said the ash fallout could contaminate drinking water and cause respiratory issues.
‘Help will be needed to restore drinking water supplies. People of Tonga must also remain vigilant for further eruptions and especially tsunami with short notice and should avoid low lying areas,’ said Shane Cronin, professor at the School of Environment, University of Auckland.

‘We are praying that the damage is just to infrastructure and people were able to get to higher land,’ she said.
Tonga gets its internet via an undersea cable from Suva, Fiji, which presumably was damaged.
Southern Cross Cable Network, the company that manages the connection, does not know yet ‘if the cable is cut or just suffering power loss,’ chief technical officer Dean Veverka said.
The Fiji-based 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.
On Tonga, home to about 105,000 people, video posted to social media showed large waves washing ashore in coastal areas, swirling around homes, a church and other buildings.
New Zealand’s military said it was monitoring the situation and remained on standby, ready to assist if asked.
Prime Minister Jacinda Ardern said there had not yet been any official reports of injuries or deaths in Tonga, but cautioned authorities had not yet made contact with some coastal areas and smaller islands.
She said: ‘Communication with Tonga remains very limited. And I know that is causing a huge amount of anxiety for the Tongan community here.’
She said there was significant damage to boats and shops along the Tongan coastline.
The New Zealand Prime Minister added Tonga’s capital of Nuku’alofa was covered in a thick film of volcanic dust that was contaminating water supplies and making fresh water a vital need.
Aid agencies said thick ash and smoke had prompted authorities to ask people to wear masks and drink bottled water.
Ms Ardern said New Zealand was unable to send a military surveillance flight over Tonga on Sunday because the ash cloud was 63,000ft (19,000 metres) high but they hoped to send the flight on Monday, followed by supply planes and navy ships.

Dave Snider, the tsunami warning co-ordinator for the National Tsunami Warning Centre in Palmer, Alaska, said it was very unusual for a volcanic eruption to affect an entire ocean basin, and the spectacle was both ‘humbling and scary’.
In Hawaii, the Pacific Tsunami Warning Center reported waves that measured 1.6 feet in Nawiliwili, Kauai and 2.7 feet in Hanalei. The National Weather Service said there were reports of boats getting pushed up in docks, but the hazard diminished as the morning went on.
‘We are relieved that there is no reported damage and only minor flooding throughout the islands,’ the tsunami center said, describing the situation in Hawaii. The tsunami advisory for the islands was lifted about 11 hours after the eruption more than 3,000 miles away.
