The Earth is a gigantic ball of semi-molten rock, with a heart of iron as hot as the surface of the Sun. Titanic amounts of heat left over from its birth and the radioactive decay of trillions of tons of radioactive elements find no escape but up. Currents of rock spanning thousands of kilometers carry this energy to the surface. Earth’s crust is the only thing in their way. It feels solid to us, but it is only a fragile barrier, an apple skin around a flaming behemoth. True apocalypses can break through and unleash eruptions tens of times more powerful than all of our nuclear weapons combined, subjecting the climate to centuries worth of change in a single year, while drowning continents in toxic ash and gases: supervolcanoes. How big can they get? And will they put an end to humanity?

Being able to freely watch quality content like this is a blessing.
The really interesting thing about Krakatoa, in my opinion, is that the biggest bang wasn't really volcanic. A smaller eruption blew out the side of the volcanic cone, allowing millions of litres of seawater to rush inside. It hit the magma, turned instantly to steam, and the force of that steam expanding is what blew the mountain apart and made a noise so loud it was heard in South Australia.
so the Earth edges itself
My favorite fun fact about Krakatoa is that there’s a fair amount of evidence that it was the main inspiration for Edvard Munch’s “The Scream”. In a journal entry, he described how he was walking with two friends when a sort of “artificial sunset” (caused by the amount of debris kicked into the air) occurred. It was so impactful on him that he made his most famous work because of it.
I don't think I will ever find another educational channel that reaches the peaks of entertainment, fun, informative, and researched as this.
Now that’s a gender reveal party
Yellowstone is it?
Kurzgesagt is like "If this blows up you and your loved ones will die. But that's what they are: LOVED ones. That means that, despite dying horrible deaths, you are loved."
Mount Semeru, Mount Krakatoa, Mount Tambora, and Mount Toba are all in Indonesia. thats amazing
The visual formula of Kurzegesagt is both simplistic and impressive, I love how it makes things I have never had interest in before interesting!
“Big booms on a scale”

As an Indonesian, it's always fascinating how our country sits directly between several tectonic plates so that there are lots of volcanoes waiting to erupt. Also, I appreciate how simple the Kurzgesagt animation always have been and the accuracy of some of the art (the houses, the plants, the general area) that got animated.
Volcanoes: exists
I'm from New Zealand and I swear they never taught me that lake taupo is actually a super volcano crater... Or I wasn't paying attention but that's not likely. Wait what was I talking about again?
This channel is incredible. From the animation, the music, narrating, and of course education. It is perfection at it's peak

VEI 2 : About 10 events per year
You forgot to mention the difference between a high silicate lava volcano and a low silicate lava volcano. The high ratio has higher viscosity, that's the perfect recipe for raising pressure and make it explode (like Krakatoa), in the other hand the low ratio has almost no power for explosion and usually keeps expelling magma for a long time (like Kilauea) 😊
