Tonga, erutta un vulcano sottomarino: l'istante dell'esplosione dalle immagini dal satellite, la cenere raggiunge 20 km d'altezza

An underwater volcano off Tonga erupted on Saturday, triggering warnings of 1.2-metre tsunami waves and evacuatio norders on the shores of Tonga as well as several South Pacificislands, where footage on social media showed waves crashing into coastal homes. Internet and phone lines went down at about 6.40 p.m. localtime on Saturday, leaving the 105,000 residents on the islands virtually uncontactable. There are no official reports of injuries or deaths in Tongaas yet although communications are limited and contact has notbeen established with outlying coastal areas beyond the capital Nuku'alofa and closer to the volcano, Jacinda Ardern the Prime Minister of New Zealand told a news conference on Sunday.

Tonga, an island nation with around 105,000 residents, lies 2,383 kilometres (1,481 miles) northeast of New Zealand. "Nuku'alofa is covered in thick plumes of volcanic dust but otherwise conditions are calm and stable," Ardern said. "There are parts of Tonga where we just don't know yet... wejust haven't established communication," she said. Satellite images captured the volcanic eruption on Saturdayas the explosion sent plumes of smoke into the air and about 12miles above the sea level. The sky over Tonga was darkened bythe ash. Concerns were growing among the Tongan community in New Zealand, desperate to make contact with their families backhome. Some churches organised community prayers in Auckland andother cities.

"We pray God will help our country at this sad moment. We hope everybody is safe," Maikeli Atiola, the Secretary of theWesleyan Church of Tonga in Auckland said, Radio New Zealandreported. 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 andlocal mobile phones were slowly starting to work, she added.

Official damage assessments were not yet available, she said, but the New Zealand high commission in Nuku'alofa had told her the tsunami has had a significant impact on the foreshore on the northern side of Nuku'alofa, with boats and large boulders washed ashore. "Shops along the coast have been damaged and a significant cleanup will be needed," she said. Australia said it will send a P8 surveillance aircraft toTonga on Monday to assess damage to critical infrastructure suchas roads, ports and power lines, which will determine the nextphase of the response effort. In the United States, Secretary of State Antony Blinken saidthe country stands prepared to provide support. PACIFIC IMPACT The Hunga-Tonga-Hunga-Ha'apai volcano has erupted regularlyover the past few decades but Saturday's eruption was so loudthat residents parts of faraway Fiji and New Zealand said theyheard it. "My entire house was shaking," said Sanya Ruggiero, aConsulting Communications Advisor based in Suva, the capital ofFiji, some 750 kms from Tonga. "My doors, windows were all rattling like hell. And mine wasnot even as bad as others. Hundreds of people ran out of theirhomes," said Ruggiero, who consults for several agenciesincluding the United Nations. Rumblings and eruptions from the volcano continued to beheard through the night, Ruggiero said. Hundreds of people weremoved to evacuation centres in Suva. Fiji Airways had to cancelall its flights due to the ash clouds. "This is the worst disaster Tonga has had in living memoryand the recovery from this is going to take years," Ruggierosaid. Experts said the ash fallout could contaminate drinkingwater and cause respiratory issues.

"Help will be needed to restore drinking water supplies.People of Tonga must also remain vigilant for further eruption sand especially tsunami with short notice and should avoid lowlying areas," said Shane Cronin, professor at the School of Environment, University of Auckland. The eight-minute eruption on Saturday triggered tsunami warnings and evacuations in several countries. The eruption caused flooding across portions of coastal Alaska and California n the United States. Floods from the tidal waves were also reported in Chile,some 10,000 kilometres away, and hundreds of thousands ofJapanese citizens were advised to evacuate as waves of more thana metre hit coastal areas.
