    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.
