#AceNewsReport – Jan.17: 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.
#AceDailyNews Media News Report: The explosion triggered a 7.4 magnitude #earthquake and ent tsunami waves crashing into the coast of the Pacific island, and left it covered in ash and cut off from aid: In the US, waves of up to 4.1 feet were recorded in Port San Luis on Saturday, and tsunami-effect waves were recorded along the coast in California, Oregon, Washington, British Columbia, and Alaska By Chris Matthews
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.
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: New Zealand Prime Minister Jacinda Ardern said the eruption was ‘hugely concerning’ and agencies were still trying to establish full communications with 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.

The eruption cut the internet to Tonga, leaving friends and family members around the world on Sunday still anxiously trying to get in touch to figure out if there were any injuries and the extent of the damage. Even government websites and other official sources remained without any updates.
Satellite images showed a huge eruption, with a plume of ash, steam and gas rising above the sea. A sonic boom could be heard as far away as Alaska.
Can volcanoes create new isalands?
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.
They layers build their way up from the sea bed to creat new islands.
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’.
Tonga’s cabinet held a crisis meeting on Sunday and was contacting development partners, a spokeswoman for Zed Seselja, Australia’s minister for international development and the Pacific told Reuters. She said Australia would sent a P8 surveillance aircraft to Tonga on Monday.
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.
Locals took to social media to share dramatic videos of the surging waves making land and crashing through homes and cars (pictured, still images from video filmed in Tonga and posted to social media on Saturday)
‘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.
In Tonga, 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.’
The explosion of the Hunga Tonga Hunga Ha’apai volcano was the latest in a series of dramatic eruptions.
Earth imaging company Planet Labs PBC had watched the island in recent days after a new volcanic vent there began erupting in late December.
Satellite images captured by the company show how drastically the volcano had shaped the area, creating a growing island off Tonga.
‘The surface area of the island appears to have expanded by nearly 45 per cent due to ashfall,’ Planet Labs said days before the latest activity.
Following Saturday’s eruption, residents in Hawaii, Alaska and along the U.S. Pacific coast were advised to move away from the coastline to higher ground and to 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,’ Snider said.
He said the waves slamming ashore in Hawaii were just under the criteria for a more serious tsunami warning.
‘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,’ Snider said.
Beaches and piers were closed across Southern California as a precaution. The National Weather Service tweeted there were ‘no significant concerns about inundation.’ Strong rip currents were possible, however, and officials warned people to stay out of the water.
On California’s central coast, the National Weather Service reported tsunami waves up to 4 feet (1.2 meters) and flooding in beach parking lots at Port San Luis. About 200 miles (320 km) down the coast, the waves were much smaller at Southern California’s Seal Beach, according to Michael Pless, the owner of M&M Surf School.
‘The waves are looking pretty flat,’ Pless said. ‘We’re hoping they reopen the beach in a couple hours.’
Crowds gathered at the Santa Cruz Harbor in California to watch the rising and falling water strain boat ties on docks. Law enforcement tried to clear people away when big surges started at around 7:30 a.m.
About an hour later, a surge went over the back lip of the harbor, filling a parking lot and low-lying streets and setting some cars afloat. In 2011 after the Japanese earthquake a series of surges cost $20million of damage in the harbour.
Although experienced surfers would consider the waves reaching the West Coast barely high enough to qualify as swells, the National Weather Service warned that tsunamis cause deceptive water surges powerful enough to pull people out to sea.
Residents of American Samoa were alerted of a tsunami warning by local broadcasters as well as church bells that rang territory-wide Saturday. 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 centre cancelled 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. In New Zealand, officials warned of possible storm surges from the eruption.
New Zealand’s private forecaster, Weather Watch, tweeted that people as far away as Southland, the country’s southernmost region, reported hearing sonic booms from the eruption. Others reported that many boats were damaged by a tsunami that hit a marina in Whangarei, in the Northland region.
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 3-mile-wide plume rising into the air to about 12 miles.
The Hunga Tonga Hunga Ha’apai volcano is located about 40 miles north of the capital, Nuku’alofa. 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.
There is not a significant difference between volcanoes underwater and on land, and underwater volcanoes become bigger as they erupt, at some point usually breaching the surface, said Hans Schwaiger, a research geophysicist with the Alaska Volcano Observatory.
With underwater volcanoes, however, the water can add to the explosivity of the eruption as it hits the lava, Schwaiger added.
Before an explosion, there is generally an increase in small local earthquakes at the volcano, but depending on how far it is from land, that may not be felt by residents along the shoreline, Schwaiger said.
In 2019, Tonga lost internet access for nearly two weeks when a fiber-optic cable was severed. The director of the local cable company said at the time that a large ship may have cut the cable by dragging an anchor. Until limited satellite access was restored people couldn’t even make international calls.
Southern Cross Cable Network’s Veverka said limited satellite connections exist between Tonga and other parts of the world but he did not know if they might be affected by power outages.
