2022 Tongan volcanic eruption was largest natural explosion in more than a century, new study finds ScienceAdvances
from Hunga Tonga-Hunga Ha'apai, one of the largest natural explosions in more than a century, generated a mega-tsunami with waves up to 45 meters high along the coast of Tonga's Tofua Island and waves up to 17 meters on Tongatapu, the country's most populated island.
"Despite its size and long duration, the mega-tsumani that resulted from Hunga Tonga-Hunga Ha'apai claimed few lives," said Sam Purkis, professor and chair of the Department of Marine Geosciences at the Rosenstiel School."The main factors that led to this, we suggest, are the quirk of the location, the COVID-19 pandemic, and increased evacuation drills and awareness efforts carried out in Tonga in the years prior to the eruption.
