    Lightning is one of those things that makes it easy to see why people invented Gods to explain the phenomena.

    how does lightning work? I’ve seen videos of people being struck like 5 times and they are fine with some scars and minor nerve trauma. What causes that person to be ok, but 300 reindeer just die?

      You get a circular voltage gradient away from the strike spot. A human with their two legs doesn’t spread along that as far as a deer’s four legs do, so they catch more voltage drop across that, which also runs through their body (along their heart etc). It just depends a lot on how and where a body is affected by electricity.

    Electrocuted, basically:

    “Lightning does not strike a point, it strikes an area,” said John Jensenius, a lightning safety specialist with the National Weather Service. “The physical flash you see strikes a point, but that lightning is radiating out as ground current and it’s very deadly.”

      That’s interesting. I have seen lightning split a tree and then follow wires into a house blowing out the wall all long the path of the wires. I have also seen it lift up decking when following underground wires.

      But if lightning hits with no lightning rod and ground is equally everywhere I guess I could imagine this result.

        I read somewhere that the induced electical field shift near a lightning strike is - while orders of magnitude calmer than the strike itself - still powerful enough to burn, maim and kill.

        I think it’s what Wikipedia calls “side splash” in the article on lightning injury?

        and ground is equally everywhere

        You make an interesting point; Lapland is known for being relatively flat, often stony and pretty much treeless. I’m sure that contributed to an increased radius.

        Part of the problem is that we have two feet. When lightning strikes the ground nearby, it creates a difference in electric potential between the foot that’s closest to the impact point and the more distant one. If that potential is great enough, then an electric currect can jump through one’s shoe, go up into the body then down the other leg and back to ground.

        Laying down only increases the surface area in contact with the ground, so the best thing to do is get inside.

            Feet have non-zero surface area so there’s still room for an electric potential between the near and far side of the foot. It’d be smaller so that isn’t an entirely terrible idea, but it is by no means foolproof.

                “Fine”. Burns are very serious injuries prone to infection. Internal injuries are way harder to diagnose and treat. That’s a rough combination.

            One Problem I could see with that is that your raised foot still needs to go somewhere. And if the resistance through the path up through your leg and to some part of your raised leg and then from there through the air back into the ground is lower than the one of the path through the ground from your lowered foot to the end of the aforementioned path then the lightning would still travel through your lower body.

    This Practical Engineering video explains the concepts behind how this happened

    TLDR: The electricity is trying to flow through the Earth, but a reindeer is a better conductor, so it flows up into the nearest leg and down out the furthest leg. If they were standing on one foot they might’ve been ok
