"a team of scientists was on a #ResearchVessel near Tonga to study the #animals that live around #HydrothermalVents. But when they lowered a remotely operated vehicle down to a vent to search for the critters, they found the seafloor, normally a hard basalt surface, blanketed in sediment... they now had a rare opportunity to document the effects of a volcanic eruption on marine ecosystems"

The Tonga Eruption Left Deep-Sea Life Buried in Ash

When Hunga erupted in 2022, ash “decimated” slow-moving species living on the seafloor. More mobile species were able to hoof it out of harm’s way.

I watched "Hidden Volcano Abyss" on SBS last night an it was both good and terrible. It bought some nice detail about the Hunga Tonga-Hunga Ha’apai eruption but they kept saying "why did X occur, scientists have no idea". In each case I was correctly able to state the reason immediately the question was posed just from my general knowledge of geological and volcanic processes. Eventually they worked around to those same answers while trying to make them out as theories of their pet volcanologist rather than standard knowledge. And while it is true that there is no orthodox way of telling whether any particular eruption will result in a caldera collapse the fact of caldera collapses and phreatic eruptions are both well established. And what even does a "drained magma chamber" mean in the context of 5 kilometers of overlaid rock strata? It certainly isn't the empty cavern that the narrator seemed to be envisaging.
Interestingly they went straight from this eruption back to Santorini. All the eyewitness accounts and records of the 1883 Krakatoa eruption seem to have eluded them. And the two eruptions are hugely similar in the way they progressed.
Could have been either far shorter or could have been vastly more interesting by comparing the timeline and phases with the Krakatoa event. C-

On Monday the media reported that the Tongan volcanic eruption was the largest in history. I can believe that, here at the top of the South Island all these many months later we are still getting these stunning 'afterglow' sunsets through the volcanic particles that were thrown up in the eruption and dispersed thousands of miles away. They happen after the sun sets. These are some we've had in recent weeks and months. #volcano #tongavolcano #tongaeruption #sunsets #afterglow
