    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.

        The picture is dumb as hell. The lava would just flow out of the big gaping vertical hole in the front.

      I think we can still work with the spirit of the solution. The main issue is that the lava will break the concrete. The solution is pretty simple. If we take some buckets of water we can pour it into the volcano creating a layer of obsidian. Obsidian is much harder and will easily contain the magma.

      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.

          Concrete does explode upon contact with molten metal…I can’t imagine how this doesn’t end up in an explosion

      Or as the guy at bike shop put it “no you can’t put duct tape on your pierced tyre. If a nail got through rubber, its probably gonna also get through tape.”

        Not that I want to defend using duct tape for this, but fixing a tyre isn’t about keeping nails out but closing the hole after the last one.
