Hunga Caldera Collapse: New Data Links Rapid Submersion to Record Tsunami
A new study in Nature Geoscience details how the 2022 Hunga Tonga eruption caused a rapid, piston-style collapse of its submarine caldera, displacing 8.9 cubic kilometers of material. This sudden subsidence, which occurred during the eruption, is linked to the generation of an extreme tsunami and the severing of underwater cables, highlighting the hidden hazards of small underwater volcanoes.
