1 . Tonga is an island nation in the South Pacific Ocean. On January 14th, 2022, an underwater volcano erupted near Tonga.
The volcano is located off the coast of Tonga. It first began to erupt on Friday. Even though the volcano was underwater, it sent a column of gas, ash, and stones 20 kilometers into the sky.
Saturday’s eruption was far larger. It’s believed to be the largest in over 20 years. The eruption caused a loud “sonic boom”, which could be heard even in Alaska, 10,000 kilometers away. The eruption caused a 5.8 magnitude earthquake, as well as tsunami (海啸) waves that traveled far and wide.
In Japan, Chile and Australia, people moved away from low-lying areas along the coast. The waves sunk boats in New Zealand and caused two deaths in Peru.
The event knocked out Internet services in the area. Like most island nations, Tonga gets its Internet through a cable that runs deep under the sea. The reports of injuries and deaths in Tonga related to the eruption couldn’t be known in time because of problems with communication.
In the following days, the smoke and ash from the volcano covered much of Tonga. ________ That was the biggest danger which might last for a long time.
New Zealand and Australia sent teams to Tonga to help out. Some of the teams used airplanes to get a better idea of the damage across the island nation. But at that time, the large cloud of ash high above Tonga was making it impossible to get a good picture of what was happening in the area from high in the air. The United States and the World Health Organization also sent help to Tonga.
