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.


Dawn is my little sister. When I was 11 and she was just a tiny baby, I hurt her really badly. I didn’t know what I did was going to cause so much trouble. I just wanted to do something nice. Something that would make us happy.

My parents made me go away for a long time. I didn’t understand why everyone was so angry. I missed my sister terribly. Even worse, I felt betrayed by the people I’d expected to understand me.

After six years of hospitalization, I got to see her again. My parents had passed away in a car accident while I was gone and I went to live with my aunt and uncle. Both were psychologists. Both understood the problem I apparently had. Still, they believed I’d learned to cope with it over the course of my rehabilitation. And they were right. I would never hurt anyone again. The mere thought of it was abhorrent.

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.”


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. 

Okay so being in the UK nothing as crazy as most of the stuff on this blog has ever happened but there’s one moment I’ll never forget as long as I live.

There was this one guy in my class, let’s call him B, who was infamous for asking the dumbest questions ever.

So this one week was the first time we had our new geography teacher and we were in the middle of our unit on tectonics and were specifically looking at volcanos. Mr C, the teacher, brought up pyroclastic flows and how they’re superheated ash and everything’s fine but then B opens his big mouth and asks something that just baffled me.

“So if you were wearing a suit full of liquid nitrogen and you stood in a pyroclastic flow, could you survive?”

And I swear I’ve never heard a dumber question in my whole goddamn life


Nice views of eruptions of Anak Krakatau, the volcanic cone growing between the Indonesian islands of Java and Sumatra.

Why yes, that there is a traced overlay of the Zelda II world map superimposed on the world map of Breath of the Wild. My my, that’s quite a claim: what could have *possibly* made so much sea water disappear?

The game tells us, actually: during the “Leviathan Bones” side quest, Akrah and his colleagues are researching into the great Leviathan (lit. whale) bones scattered about Hyrule, with the great ones being said to rest in Eldin’s Deplian highlands, Hebra’s north slope, and Gerudo’s Dragon’s Exile. Taking photos with your Slate of each of these massive fossils will result in these scientists giving their theories on what caused the deaths of these mysterious giants: death by a volcanic eruption; death by Ice Age; death by drought.

What if I told you, all three happened…in that order?

The quite active volcano beneath the “Valley of Death” in Eastern Hyrule must have erupted quite violently, raising itself up higher from the shallow seas, buckling and breaching the water’s surface to form a grander cone: the heat of this intense eruption—and its likely massive pyroclastic flow—decimated the surrounding regions, killing the first leviathan.

The after effects of this eruption were felt almost immediately: the ash and particulates clogging the skies, dropping the temperature worldwide, and leading into a dip in the climate, with less sunlight breaking through the ash-choked clouds…leading into longer, harsher winters—highlands glaciating under pack ice—leading to the death of the second leviathan.

Now, as the climate is cooling and the air mass is drying, less frequent rains for a period of time leads to a massive drought, culminating in the death of the final leviathan.

These three consecutive changes combined would lower the sea level dramatically, and it is *exactly what we see*! The inland Cliffs of Quince and the upper cliffs of Loshlo Harbor, in southeastern Hyrule, exhibit weathering typical of tidal erosion: yet they’re far above the current sea level. And then there are the numerous *other* bones scattered about Hyrule, seemingly from giant serpents and whales alike—the proverbial sea creatures of the deep. And last but not least, there’s rock salt: a product of the desiccation of the “ancient seas”.

Let’s not even mention how so many of the landforms and locations line up near-perfectly between these two overworlds (Spectacle Rock, Maw/Valley of Death [Mountain], Rauru, the river sources of Saria, swamps and marshlands, Maze Island, etc.)

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.

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).

i hate hate hate hate that post going around of the two dead Pompeii victims that were actually two men in a loving embrace. all i see are comments like “LMAO HE WAS SUCKING DICK RIGHT UNTIL THE END!!!!!” because of the odd position they’re in

that is so fucking disrespectful and disgusting. these two men, and all Pompeian victims, died horrible, awful, nasty deaths. They saw the rushing pyroclastic flow race towards them, with gas so hot, your blood boils and your brain vaporizes. Your bones literally explode. They were scared. They didn’t know what was happening other than imminent death. And in their final, harrowing moments they chose to embrace and comfort each other as they waited for it to end.

And all you see is an opportunity to sexualize them. Shame on you.



If we are not off the ground at least 20 minutes before it hits, the electromagnetic charge and the pyroclastic cloud will shut down the rocket’s avionics, meaning it won’t fly. That gives us 90 minutes to run a six-hour preflight check, retrieve the oxygen generator from the lighthouse, plus turn a cockpit that can carry two into one that can carry eight and load the cargo hold with enough food to keep us from starving in space while we wait for the algae to bloom.
