Scientists say a volcanic eruption could happen any moment near the evacuated town of Grindavik.

    …and they’re gonna make the volcanoe pay for it.

    Something about volcanoes not sending their best. Look at ehat happened to Pompeii

    I’m very interested in the engineering of this. Lava is heavy (3000kg/ cubic meter). Its anywhere from wet tooth paste to thick bread dough when it flows (depending).

      This isn’t even close to my wheelhouse, but I’m curious to know what kind of resistance is really required here. Yes, the density is very high, but are we expecting more than a stream coming in? If it builds up, how long does it take for the older bottom layer to cool down, rendering it harmless? Am I even thinking of the right metrics here?

      And say a wall could be built out of sandbags like they do for floods. Would that make a layer of glass on the surface? Or beyond and just knock it over?

        Would it just smoosh up and like ‘crawl’ over?

          A large dyke is being constructed to divert potential lava flows around the plant

          Lava, like water, prefers to go the easy route. You do not build a wall to stop it face to face, but offer a more easy route right and left of your “wall”, so the force of the lava is halved AND it will likely take the more easy routes and not bother to try and crawl over your construct.

          A wall directly in its path only makes sense when you are already somewhat far away from the volcano, so the lava is very slow and not as hot as in the beginning anymore and then it is rather a pile of earth piled against a smaller part of the stream of lava for days again and again and not a real static wall. A video for that: https://www.youtube.com/watch?v=xWbQOqaOxjg The scale of this … kudos to people who can live near a volcano, I am way to scared for that.

    They should built a giant ice wall to protect the power plant and the rest of the island from lava.

    They probably need a group people to watch if they lava is coming though, since the night can last a very long time they can call this group something like the Night’s Watch.

    I’m just sending random ideas.
