| The rapid syn-eruptive submarine caldera collapse at Hunga enhanced tsunami hazards, with tsunami wave heights reaching about 40 m at distances up to 100 km and associated volcaniclastic density currents damaging seafloor infrastructure. | CAUSAL | Supported | 0.9526 | 1 of 4 | 118 |
| Repeat seafloor mapping found that the 2022 Hunga eruption deepened the caldera from about 150 m to about 850 m and displaced 8.9 ± 0.1 cubic kilometres, of which 6.85 ± 0.05 cubic kilometres was attributed to caldera collapse. | QUANTITATIVE | Supported | 0.9781 | 1 of 4 | 107 |
