Tonga volcano eruption surpasses nuclear explosion in power, study finds.

The Hunga Tonga-Hunga Haʻapai undersea volcano eruption in 2022 was larger than any natural explosion in the past century or even any U.S. nuclear explosion, according to a study released Friday in Science Advances. It rivals the massive Krakatau volcanic explosion near Indonesia in 1883 that took more than 36,000 lives, though the Tongan volcanic explosion in the southwest Pacific caused four deaths. The study also showed why the tsunami was particularly damaging but how it could have been much worse.
