Этна: 5 землетрясений, 5 жерл

Between August 7th and August 11th, 2026, five new eruptive vents opened on Mount Etna — at 3,200 meters, 2,750 meters, 2,360 meters, 2,090 meters, and 1,900 meters. Thirteen hundred meters of descent in five days, every vent on the volcano's eastern flank. One of them alone produced an estimated 2.81 million cubic meters of lava and a flow 4.5 kilometers long. By August 13th the leading front had pushed down to 1,340 meters, past Rocca Capra, into the Valle del Bove. Catania Airport has been closed or restricted for most of a week — roughly 630 flights diverted between August 6th and 12th, 36% of 1,974 scheduled flights cancelled, ash carried 220 kilometers south to Malta. And the flank all of this is happening on is the same flank that a seafloor sensor array caught slipping more than four centimeters in eight days in May 2017, with no eruption behind it at all. This video covers: the day-by-day vent sequence recorded by INGV's Etna Observatory; what the "unstable eastern flank" actually is, and the Pernicana and Timpe fault systems that bound it; the 2018 Science Advances seafloor study that overturned what geologists thought was pushing this mountain sideways; the aviation shutdown and the 1669 eruption that buried fourteen towns; why Kīlauea's south flank and its 2018 magnitude 6.9 earthquake are the closest working analog; the Valle del Bove collapse of ~8,000 years ago and the drowned Neolithic village at Atlit-Yam; and what INGV is and is not saying about any of it. Geosphere covers geological events with the numbers attached, the caveats included, and the parts other channels leave out.
