The massive Tonga volcanic eruption in 2022 triggered unprecedentedly fast underwater currents, hitting speeds over 120 km/hr, according to a new study.

According to a new study published on and New Scientist, the Tonga volcanic eruption in 2022 triggered the fastest underwater currents ever recorded, hitting speeds over 120 km/hr. The eruption of the submerged Hunga Tonga–Hunga Ha apai volcano triggered a fast-moving and destructive underwater debris flow. The study also found that the underwater flows reshaped the seafloor. The eruption affected the climate around the world. Scientists are still studying the eruption and making remarkable discoveries about what turned out to be one of the world’s most powerful volcanic eruptions.
