The South Pacific island nation of Tonga, its volcanic island only 65 kilometers from the capital erupted at 2 degrees on the 14th and 15th, followed by a tsunami that hit the country, New Zealand, Japan, the United States and Canada, resulting in the country's disconnection from the outside world for up to 5 days, trees and buildings were razed to the ground, the airport runway was covered with volcanic ash, and acid rain caused by chemical gases was likely to harm crops.
Comprehensive foreign media reports, the undersea volcanic eruption caused 3 deaths in Tonga, the Royal Tonga Consulate released a social platform photos showing that the subsequent tsunami more seriously destroyed Tonga's villages, resorts and many buildings, resulting in the country of 105,000 people once interrupted foreign communications, the capital was covered with volcanic ash, the international airport runway was also covered with a thick layer of volcanic ash.
The photos were released after the Kingdom of Tonga restored some of its external cables, but the country's only telecommunications operator said it would probably take another month or more to restore all cable and network services.
Journalists from the capital revealed to the media that the local residents of Tonga are doing their best to clean up the volcanic ash and all kinds of dust left behind after the eruption, but the depletion of drinking water is probably a major problem in the future, although each family has its own water supply tank, but it has long been buried by various dusts, it is not very safe to drink, food may allow us to survive in the next few weeks, but I am not sure whether the water is enough.
Journalists said some villages in the western part of the Kingdom of Tonga have been hit hard and that authorities are now trying to send people to other islands for inspection.
The Australian Defence Minister said that a Royal Air Force aircraft full of humanitarian relief supplies and a sweeper to help clear the airport runway had flown from Brisbane to Tonga; the New Zealand Foreign Minister said in a statement that the New Zealand Air Force had sent C-130 transport aircraft to the Kingdom of Tonga, carrying various relief supplies including water containers, temporary shelter supplies, generators, hygiene supplies, household supplies, communication equipment and other relief supplies.
The Japanese government said on the 20th that it would provide drinking water and equipment to clean up volcanic ash through the Japan International Cooperation Agency.
The U.N. said the undersea eruption had severely affected at least 84,000 people in the Kingdom of Tonga, which makes up more than 80 percent of the country's population.
Scholars at the University of Auckland warned that the large amount of volcanic ash from the submarine volcano is likely to cause damage to coral reefs for a long time, eroding the coastline and damaging the development of fisheries; and after the volcanic eruption, sulfur dioxide and nitric oxide are continuously released, and acid rain will occur when the two gases interact with water and oxygen in the atmosphere, which will cause a wide range of crop losses, affecting the staple food of the Tongan people, including taro, corn, bananas and garden vegetables, and food security may be seriously affected.
In addition, once the coral reef is destroyed and eroded, it will lead to sea level rise in Dongjia and will not be able to stop the storm caused by the typhoon.
The WHO believes that the scattering of volcanic ash and various dusts in the air is a major concern for Tonga at present, and calls on local residents to wear masks at any time and drink bottled water outdoors instead of inhaling too many suspended particles.
