Australia and New Zealand have sent humanitarian supplies including temporary shelters, generators, hygiene kits, and communications equipment to the tsunami-hit pacific nation.
Aircraft carrying much-needed humanitarian supplies from Australia and New Zealand have begun arriving in tsunami-hit Tonga, 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 on Thursday 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 landed in the Tongan capital Nuku'alofa.
"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.
Tonga running out of drinking water
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.
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.
The United Nations said that about 84,000 people – more than 80 percent of the population - have been badly affected by the disaster.
"They have been affected through loss of houses, loss of communication, what we understand is the issue with the water," UN spokesman Stephane Dujarric told reporters.
The most pressing humanitarian needs are safe water, food and non-food items, he said.
"Water is really the biggest life-saving issue. Water sources have been polluted, water systems are down."
New Zealand said Tonga, one of the few countries to be free of the coronavirus, had agreed to receive two of its ships carrying aid and supply, despite concerns about importing a Covid-19 outbreak that would make matters worse.
Vaccination against the virus is as high as 90 percent among Tongans.
The ships, which were carrying 250,000 litres of water along with other supplies, will arrive on Friday.
The Hunga Tonga-Hunga Ha'apai volcano erupted about 65 km from the Tongan capital with a blast heard 2,300 km away in New Zealand.
Waves reaching up to 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.
