A pyroclastic surge, which can top out at 290mph, with a high temperature of 1,830 °F. A pyroclastic surge is a fluidized mass of turbulent gas and rock fragments which is ejected during some volcanic eruptions.


The Indonesian Volcano Sinabung was extremely active last week, sending up several clouds of ash. That ash used to be magma that was in tact in its neck, but gases in that magma fractured it into ash. During the eruption, super-heated gases and ash mix together and rise upwards because the combination of ash and hot gas is still denser than the atmosphere. However, when it zooms in look for the small areas of ash that seem like they’re falling off the side. These are small pyroclastic flows coming off the main ash cloud. They form when part of the ash cloud becomes too dense - either too much ash or becomes too cold. They are still several hundred degrees C and begin moving down the volcano in channels - these are the parts of an eruption like this that can damage and kill.


A hike to the crater lake at Pinatubo, Philippines

A pickup truck flees from the pyroclastic flows spewing from the Mt. Pinatubo volcano in the Philippines, on June 17, 1991.  Behind it, the searing hot, bone-charring ash charges with the speed of a jet engine, preparing to swallow the car whole and burn the occupants alive. As you can see, it is a hot and dense cloud that is literally thousands of times bigger than the car it’s chasing. This was the second largest volcanic eruption of the 20th century.

I know I’ve made a lot of posts about Jack’s Canadian ass visiting The Pyroclastic Hellscape (Madison, Georgia) and basically dying, but I’m going to add another one because it’s summer on my side of the world and I’ve just remembered the tie-your-shirt-up-on-one-side-so-it’s-a-crop-top thing to keep cool and just… Jacques…

Jack: Look what I just saw online! It’s such a simple idea, I can’t believe I didn’t think of it.

Bitty: Jack…

Jack: I might just survive Georgia after all!

Bitty: …

Jack: From now on, all my tops are crop tops.

Bitty: uhhh…

Jack: You okay Bits, you’re all red. Is it the heat?

Bitty: Where did you get… high wasted denim shorts… that short… in your size…? And - not that I’m staring at your thighs at all - but… did you… shave your legs?

Jack: It’s hot

Now, there are one of two ways that Jack could cause a riot in that outfit. The first is by wandering around the Deep South (deep as in geographically and also in the terrifying way that parts of the ocean are deep) looking like the better looking, much chiller younger brother of Frankfurter from the Rocky Horror Picture Show and, when questioned by passers-by, yelling things like “gender divisions are dead!” just so he doesn’t have to give himself heatstroke by putting jeans on.

The second way is that ass in those shorts. I guess it depends on what part of Georgia he’s in. Either way, he’s the gay awakening of at least five people, causes a clique of slightly tipsy grandmothers to reminisce in giggles about the sixties, makes one “cool” pastor consider wearing crop tops if that’s what the Teens are into these days, and sparks a brief but exhilarating fashion trend among a local baseball team.

And eventually Jack learns the main difference between two of his closest friends; Shitty hears about it via twitter and immediately tries to convince him to become a high profile advocate for gender activism, Tater hears about it and immediately buys himself a crop top.


Classic video of Katia Kraft - volcanologist who traveled the world visiting eruptions and eventually was killed in a pyroclastic flow in Japan. This lava flow was at Katla volcano, Iceland.

Don't sell yourself short, you're definitely way more destructive than pyroclastic ash. Personally, I rate you up there with the 'Yellowstone Super-Volcano', which is just below the 'Eventual Meteor of Doom That Will Inevitably Destroy The Planet'.

“With any luck, I will still be around when the caldera explodes. That would be a treat to watch … from afar. From very afar.”

Perfect Pizza Toppings

While having lunch with the gorgon Embers J. Lapilli at her pizzeria, Pyroclastic, we got to talking about the wide variety of clientele that come in through the door — or through the floor, depending on the time of day. Pyroclastic has a subterranean entrance to better serve light-sensitive undead customers.

Vampires: “No garlic, lots of sauce. Extra cheese, as many kinds as we have. Top with unwashed mushrooms! Many apparently enjoy the earthy taste. Occasionally they request coffee grounds, too.”

Mermaids: “Sausage and bell peppers. We make a special dough with sea water for ‘em and they say it makes ‘em feel right at home.”

Earth elementals: “We call it ‘mud pie!’ Bits of gravel sprinkled into a thin mud sauce served on a crust of sod. Dandelions or milkweed are common requests, though some ‘em prefer thistles.”

Dragons: “Oh yeah! Surprising I know, but we get a lot of ‘em. Some shape shift down in size and eat at a table, but the young ‘uns, who haven’t mastered that spell? Well, we have a knoll out in the back behind the shop. They lay ‘round up there. Whatever their size, we ask ‘em for some notice as they tend to eat about a dozen pizzas at a time — each!”

Water Nymphs: “Dragonflies and sea slime. Lotssah sea slime.”

Robots Who Have Become Sentient and Wish to be Social: “They always try to flirt with our pizza oven and I have to shoo them away. We fix ‘em up with some circuit boards and cheese-covered bolts. No one goes hungry at Pyroclastic.”

Watch on

In 2009, the International Space Station flew over the Sarychev Volcano on the Kamchatka Peninsula just as it was erupting and punching a spectacular hole in the clouds. The photos and videos of it are some of the best we’ve ever seen of an erupting volcano from above. Take a look at the pyroclastic flows streaming down the sides of the peak as the station passes (shaking is the camera position adjusting as the ISS moves).

Major volcanic eruptions can be accompanied by pyroclastic flows, a mixture of rock and hot gases capable of burying entire cities, as happened in Pompeii when Mt. Vesuvius erupted in 79 C.E. For even larger eruptions, such as the one at Peach Spring Caldera some 18.8 million years ago, the pyroclastic flow can be powerful enough to move half-meter-sized blocks of rock more than 150 km from the epicenter. Through observations of these deposits, experiments like the one above, and modeling, researchers were able to deduce that the Peach Spring pyroclastic flow must have been quite dense and flowed at speeds between 5 - 20 m/s for 2.5 - 10 hours! Dense, relatively slow-moving pyroclastic flows can pick up large rocks (simulated in the experiment with large metal beads) both through shear and because their speed generates low pressure that lifts the rocks so that they get swept along by the current.

Awesome view of the pyroclastic flow remnants and island, Montserrat volcano.


Filming a pyroclastic flow in Japan, 1991. A pyroclastic flow is a fast-moving current of hot gas and rock which reaches speeds moving away from a volcano of up to 700 km/h (450 mph). The gas can reach temperatures of about 1,000 °C (1,830 °F).

Now this is the real horrors of our world. Imagine being caught in that!

Karymsky (Russian: Карымская) is a stratovolcano and lake on the Kamchatka Peninsula, Russia, here photographed in winter, with the crater lake beyond. Karymsky is the most active volcano in the region and has been erupting continuously since a powerful earthquake struck the region in January 1996. The initial eruptions projected an estimated 30-40 million tons of pyroclastic material, saturated with acidic fluids, into the air, turning the nearby freshwater lake into a toxic chemical soup and decimating its ecosystem. Scientists are monitoring the volcano closely and despite the ecological catastrophe, Karymsky Lake is slowly recovering to pre-1996 conditions.
