    If you put concrete over the volcano, how are you going to throw virgins in as a sacrifice to the volcano god? Just asking for trouble here.

    This is literally what happens when a volcano erupts. Magma solidifes at the top and creates a plug, which builds pressure until it explodes.

    Oh I get it! If you stack rock on the hot rock, you can stop the hot rock from moving the rock with more rock!

    … Unironically, this DOES work … sorta’. Though it’d be dumb to do by man, because a ‘rock plug’ is exactly what forms at the top of many volcanos after the magma cools. It’s why many volcanos have flank eruptions where magma pushes through some side crack, or build and build until the rock plug pops catastrophically.

    Of course some volcanos don’t have the right mix to form rock plugs, and any non-dormant volcano can pop them, but the point is it does have an effect that can delay and redirect eruptions.

    If humanity doesn’t kill itself off soon (bad news on that front), I wouldn’t be surprised if one day we’re building megastructures around volcanos specifically to manage them instead of being subject to them.

        Absolutely TONS of info, though I’m not a geologist, nor have I studied much, so I sadly do not know of any solid references I could simply point at. I’ve just picked up a few details over the years watching random geology videos on YouTube.

        GeologyHub makes frequent short videos on current activity, and he always comments on the mechanisms at play, and even makes and explains his educated guesses on what will happen. A plug forming comes up quite often when eruptions slow, even in eruptions that are destined to continue erupting.

      This has the vibe of “Grifting a bunch people who have no sense and a way too much money on their hands”. I’m in.

      Edit: Missed a word

    I just realised, that I first learned about pressure as a kid, when watching cartoon characters trying too stop a leak using body parts.

    Prevent harmful eruptions with one simple trick. Frees up more time for your other hobbies, like making pipe bombs.

      More like a champagne bottle than a cannon really. The concrete/asphalt cork will just go flying and barely slow down the eruption. Might make the initial part of the eruption a bit more “spurty,” since there’s bound to be a ton of kinetic energy behind that cork being ejected.

    If pressure builds up we won’t risk anything because the cement would just be propoulsed in the outter space and not hurt anyone.

      Damn straight! Gotta teach those space bugs a lesson about messing with Buenos Aries.
