    As a politician I can assure you that if you vote for me I will put into law that volcanoes will be forbidden to erupt in our wonderful country.

      Excellent analogy, but now I want the math. Think we could push this past the gravity well? Fuck space elevator, I got ejecto-volcano cuz.

        I’m pretty certain that it would destroy whichever object was launched. The air friction alone would tear it apart.

        Isn’t a space cannon or whatever it’s called a very old sci-fi idea?

          It’s like the oldest, it’s how Jules Verne sent men to the moon in “From the Earth to the Moon”

            Pretty much as soon as a cannon got invented and shot, some guys were like “…maybe we could shoot ourselves out of that…”

              New idea: build a small town on top of the block that’s placed on top of the vulcano and start exploring space(and colonise other planets).

    Would concrete even hold. I mean lava is molten rock and cement is kind of a rock. So wouldn’t the cement melt before pressure could build up?

      Even if the plug would hold the volcano would just split open another hole in the earth and erupt from there

      Most cements melt at a higher temperature than most lava gets to, so it would be solid chunks of cement getting blasted miles out when the pressure builds high enough to erupt

        It probably wouldn’t melt, but if you heat moist concrete it will spall ans crumble to bits before too long.

    That lava already has to break through literal kilometres of rock to get there. A few hundred (let’s be generous) extra meters of pourable rock ain’t gonna do shit.

      Not to mention the average normal size of an opening you’d have to plug to begin with. Even if it didn’t just drain down the hole or dissolve the moment it got to lava, it would be a ludicrous amount of concrete just to make a layer a few feet thick. Even if you did manage to make a plug a hundred or more feet deep and it didn’t melt or move, an eruption would likely just blow the mountain apart from around it.

        All you’d need is ultra fast drying lava-proof concrete. I’m surprised no one has thought of that yet. Then once the crater vent is fully plugged you would just need to coat the rest of the mountain in the same concrete. Voila, problem solved.
