The Extraordinary and Disastrous Eruption of the Hunga Tonga-Hunga Ha’apai Volcano

The eruption of the Hunga Tonga-Hunga Ha’apai Volcano in January 2022 was the largest our planet has seen in decades, wreaking destruction on the island nation of Tonga in which the volcano resides. Studies of this volcano can help us understand the causes and effects of such massive eruptions, and may even give insight into the geological processes that have shaped the landscape of Mars.

The blast released a massive amount of energy, equivalent to between 4 and 18 megatons of TNT, which is hundreds of times more powerful than the nuclear bomb dropped on Hiroshima. The explosion created a low-frequency pressure wave that circled the Earth, causing the entire atmosphere to oscillate. Ash has coated the islands, causing a serious shortage of clean drinking water, and a tsunami caused by the eruption wrought widespread damage. The effect on...
