Tonga is cleaning up after it was hit by a tsunami and covered in volcanic ash. The undersea volcano erupted on Saturday. Experts say it was the world's biggest eruption in 30 years. It sent tsunami waves to Japan. It also destroyed large parts of Tonga. Ash is making it difficult for normal life to return. A lot of the work cannot go ahead until the ash has gone. It buried buildings and is blocking many of the country's roads.

Tonga called the disasters a one-of-a-kind event. They have badly affected life on the island. The volcano cut Tonga's underwater Internet cable. Engineers are trying to fix this. It is difficult to fly aid into the country because of damage to the airport. Tonga shut its borders in 2020 to keep COVID-19 out. It was "covid-free" before the tsunami. It now fears international aid workers could bring a "tsunami of COVID-19" into the country.
