At https://phys.org/news/2023-09-tonga-volcano-unleashed-fastest-undersea.html … the Hunga Tonga volcano, in 2022, unleashed the fastest underwater currents ever recorded, according to a new study. Fastest ever should come with a qualification. The records don’t go back very far. It is a pretty meaningless thing to say hut it is typical of modern speak where we have oceans boiling because of global warming. Everything is amazing, or out of this world. The adjectives leap off the mouth but many of them are overstatement. In this case it might not be so – although in history there must have been many other examples of submarine volcanoes causing problems. It is just that they have not been recognised by the scientific community. In other  words, we should not be too cynical of the hype  surrounding the report. It says that the submarine volcano sent rocks, ash, and gases racing across the Pacific seafloor – at 76 mph. Many volcanoes lie under the ocean and very few are monitored. They are poorly understood. See https://doi.org/10.1126/science.adk0181 … but did the volcano also contribute to this year’s ocean warming?
