Tonga volcanic eruption: Aid to arrive as airport opens, phone lines partially restored

Aircraft carrying much-needed humanitarian supplies from Australia and New Zealand will arrive in tsunami-hit Tonga on Thursday, as the South Pacific island finally made contact with the rest of the world after being cut off for five days.

Australian Defence Minister Peter Dutton said a Royal Australian Air Force aircraft loaded with humanitarian supplies and a sweeper to help remove ash from the airport runway had left Brisbane and another aircraft would depart later on Thursday.

New Zealand's Foreign Minister said its air force has also sent a C-130 Hercules from Auckland, which will land in the Tongan capital Nuku'alofa at about 4pm New Zealand time.

"The aircraft is carrying humanitarian aid and disaster relief supplies, including water containers, kits for temporary shelters, generators, hygiene and family kits, and communications equipment," Nanaia Mahuta said in a statement.

The delivery of supplies will be contactless and the aircraft is expected to be on the ground for up to 90 minutes before returning to New Zealand, she said. Tonga is Covid-19 free and is concerned that aid personnel may bring the virus.

Japan said on Thursday it would send aid including drinking water and equipment for cleaning volcanic ash through the Japan International Cooperation Agency.

The explosion of the Hunga Tonga-Hunga Ha'apai volcano, which has killed at least three people, sent tsunami waves across the Pacific on Saturday, badly damaging villages, resorts and many buildings in Tonga and knocked out communications for the nation of about 105,000 people.

Telephone links between Tonga and the wider world were being reconnected late on Wednesday, though restoring full internet connectivity is likely to take a month or more, according to the owner of the archipelago's sole subsea communications cable.

Speaking to Reuters from Nuku'alofa, local journalist Marian Kupu said Tongans were in the process of cleaning up all the dust from the volcanic eruption but feared they may run out of drinking water.

"Each home has their own tanks of water supply but most of them are filled with dust so it's not safe for drinking," Kupu said.

A few villages on the Western side of Tonga were very badly hit, she said.

"I won't say we are expecting more deaths but as we are speaking the government is trying to fly to the other islands to check over them."

Asked if there were enough food supplies, she said: "I can say maybe we can survive for the next few weeks but I'm not sure about water."

Meanwhile, Tongans abroad were frantically calling their families back home to ensure their safety.

"Today there's a sigh of relief as we are able to communicate with our loved ones back home," said John Pulu, an Auckland based Tongan, who is a television and radio personality.

"We are breathing and sleeping a little better," he said.

WIDESPREAD IMPACT

The United Nations said that about 84,000 people – more than 80 per cent of the population - has been badly affected by the disaster.

Waves reaching up to 15 metres (49 feet) hit the outer Ha'apai island group, destroying all the houses on the island of Mango, as well as the west coast of Tonga's main island, Tongatapu, where 56 houses were destroyed or seriously damaged, the prime minister's office said.
