Behold a photo of a massive lava bubble, taken by the United States Geological Survey in 1969.
It's from the long eruption of the Kīlauea volcano in Hawaii, which began on May 24, 1969 and went on for a remarkable 1,774 days.
That bubble above is about 65 feet high, but apparently other bubbles were as huge as 246 feet!
As Smithsonian, via Live Science, reports:
Lava fountains erupt either from isolated vents in lava lakes, or from lava tubes that are penetrated by water, according to the USGS. The formation and expansion of gas bubbles in molten rock pushes powerful streams of lava into the air—typically in a haphazard fashion, with the fountains spurting every which way. It is rare, the USGS notes, for the fountain to take the shape of a dome, like the one seen at Mauna Ulu.
In a 1979 report, the USGS wrote that the dome fountain appeared frequently during the October event, which “lasted for 74 hours, nearly twice as long as any other fountaining episode of the eruption.” The report also notes that the dome had a mottled surface, caused by solidified crust getting mixed with liquid lava. As part of the dome slid away, experts could see a lava core inside, indicating that the dome was “not simply a large bubble.
By ‘grace of God,’ no one was injured in a massive explosion at the Androscoggin Mill in Jay, Maine, earlier today, reports the Bangor News.
Last week Trump infamously suggested nuking hurricanes. Loopy, of course — but it also put me in mind of a similarly bananas idea from 1965: Using nukes to dig ditches and excavate earth. As Matt Novak notes in the Paleofuture vertical at Gizmodo, Athelstan Spilhaus — a scientist and educator — wrote the comic “Atomic […]
I’ve lived long enough in America to know that… A) “Shelter in place” means “you’ll probably be OK”, and that… B) There is no footage so awesome it can’t be ruined by graphics, chyrons and the inane narration of news presenters.
Right tool for the right job. You probably heard a parent or grandparent say it at least once at some point. And it’s true in so many cases. If you spot a small tear in your living room curtains or near to hem a pair of pants, you can always use the good old fashioned […]
The world is holding its collective breath. As states begin cautiously reopening, no one is sure exactly what to expect. But one thing is clear: most Americans are worried about their bank accounts. By the end of March, the average American household was spending 40 percent less on their credit cards than they were one […]
Over 25 years, eBay has carved out its space as the commerce hub of choice online. With 182 million users worldwide, that works out to about 35 percent of all US mobile users who shop those eBay storefronts. But did you know there are usually around 1.3 billion — with a B — active for-sale […]
