Small Undersea Volcanoes Could Trigger Surprisingly Large Tsunamis, Hunga Study Finds
New research into the devastating 2022 Hunga volcanic eruption in Tonga suggests that even relatively small underwater volcanoes may be capable of generating dangerous tsunamis when their calderas collapse rapidly. Detailed mapping of the seafloor has given scientists a clearer picture of how Hunga’s roughly 2.5-mile-wide caldera sank nearly two-thirds of a mile during the [...]
Scientists reconstruct one of this century's most explosive volcanic eruptions to explore its role in a tsunami
In 2022, the eruption and collapse of an underwater volcano in Tonga caused a devastating tsunami that killed four people, disrupted seafloor ecosystems and damaged critical seafloor telecommunications cables. It was one of the most powerful volcanic events this century.
The eruption of the Hunga volcano in 2022 caused the soil of its lower sea caldera to fall from about 150 to about 850 meters of water depth. New high-resolution maps show that 8.9 cubic kilometers of material were displaced. According to the researchers, the rapid, piston-like burglary has probably increased the enormous strength of the accompanying tsunami. Southampton (England).
