00:00A new study has revealed the scale of Hunga Volcano's collapse in Tonga.
00:04The collapse happened during the volcano's catastrophic eruption in January 2022.
00:10Scientists used seafloor mapping to compare the volcano before and after the eruption.
00:15They found the center of the volcano collapsed by more than one kilometer.
00:19Around 8.9 cubic kilometers of material was displaced during the collapse.
00:24Researchers say the collapse occurred during the eruption's most intense phase.
00:29It triggered extreme tsunami hazards across the surrounding ocean.
00:32The eruption also produced a massive plume that reached the stratosphere.
00:37Underwater cables were also broken during the event.
00:40The findings show how submarine volcanic eruptions can create multiple hazards at once.
00:46Scientists say detailed seafloor surveys can help improve understanding of these powerful events.
00:51The research provides new insight into the risks posed by future submarine volcanic eruptions.
