The eruption of the Hunga Tonga-Hunga Ha'apai volcano in Tonga has allowed scientists to better study how the atmosphere works, enabling them to predict how the changing climate will affect future weather.

The underwater volcano became active in December 2021 and eventually erupted on January 15, 2022. In the weeks leading up to the eruption, the volcano began to spew a dense plume of black ash, sulfur dioxide and steam. When the volcano erupted in one of the biggest volcanic events in modern history, it destroyed many homes on nearby islands with 100,000 times more energy than the Hiroshima nuclear bomb, sent out a pressure wave that circled the globe multiple times, and produced a cloud of ejecta that towered over 30 miles high.
