Mount Ontake in Japan rises 3,067 meters above sea level — a windswept giant standing head and shoulders above densely forested hills. This ancient volcano is a popular trekking site. A trail traverses its ash- and boulder-strewn ridges. There are several huts and a shrine. On September 27, 2014, hikers took advantage of a blue sky and gentle wind. At 11:52 a.m., over a hundred of them stood on the summit, eating snacks and taking photos. Disaster struck with little warning.
The windows and doors of a nearby hut rattled, vibrated by a low-frequency shock wave inaudible to humans.
People glanced around curiously and quickly saw it — half a kilometer down the southwest slope, a gray cloud billowed from the mountain.
The ash cloud swept over the summit with a blast of hot air, leaving people shaken and blinded, but otherwise unhurt. Disoriented in that gray fog, they couldn’t see what arrived soon after.
Thud-thud. Thud. Rocks blasted out of the mountain rained down from the sky. The barren mountaintop offered no shelter to those who desperately sought it in the swirling, gagging dust.
The tempo of hail quickened, as millions of rocks came down — most smaller than baseballs but some as large as beach balls. More and more people fell.
Roughly a million tons of ash and rock spewed from the mountain that day, ejected through several craters that hadn’t existed a moment before. Fifty-eight people died, most killed by falling rocks. Five others were never found.
When scientists investigated the aftermath, they found no new lava flows and no freshly formed ash. What exploded from the mountain wasn’t lava or fire; it was water.

Volcanoes are fascinating and best observed from drone footage.
People who get to close to them stand a higher risk of dying a very un pleasant death.
WUT! I never knew! 🌋🤔🔥
Love how they throw all those numbers around: 600,000, 70,000. Prove it— you can’t.
I remember watching it..................
Geology 101
What happened once will happen again.....................
Could? It will in its own time, and in geology that can be a very long time.
Must be Spring... Yellowstone articles are coming out again...
Oh noes! We’se all goin to die! 🙄
It’s low hanging fruit in the scariness orchard. It’s fairly certain that it will explode sometime in the future and it could actually happen any time. Nobody is going to have to worry about being wrong because you don’t have to specify a date, unlike Covid which was a dud as far as disasters are concerned. When it does happen, no amount of preparation is going to make a difference unless you deliberately move as far away as possible.
I welcome it
Talk about climate control
What ever would people do with the panic punks on the internet these days.
Since the last super eruption, there have been many smaller eruptions there in history. The west thump of the lake is evidence.
Lastly, there isn’t enough eruptable magma in the chamber for a larger super volcanic eruption. How do they know? Becsuse they figured out how to use seismic information for that.
Now, if you panic punks want to see one that would set you off, take a look at Campi Flegrei.
Some of us, like myself, talk to geologists who like to keep up with the latest on certain systems.
BTW, Campi is barely considered a super volcano. Outside of its original eruption 30 to 40 thousand years ago, it hasn’t come close to being within the classification of having such an event.
But, the location, the type of material and that much of the original caldera is within the bay, makes it a difficult system to study. Vesuvius is directly connected to that volcanic system.
As farcas yelloeston? Yup. It will erupt. Thousands of years from now.
This describes a phreatic eruption, not the supervolcano catastrophe people fantasize about. Unless like the unfortunate Japanese hikers you might be standing there by the summit. Then it’s a catastrophe.
