Why would all the nails be bent downward?

During a thunderstorm at my sisters house, every nail in her walls were bent pointing downward after one particular lightning strike. Anything she had hanging on the walls all fell to the floor and every nail was bent down. I can't understand how lightening could bend metal nails in such a way. And these nails were like 8d and 16d so they weren't tiny brads.

Mise à jour:

My sister and her Granddaughter were inside the house at the time. The noise was so loud it broke two windows and at the same moment, anything hanging on the walls fell due to the bent nails.

She thought maybe the lightning struck her house, but wouldn't that have started a fire? I think it might be some kind of magnetic thing? Perhaps the change of atmospheric conditions traveling in another direction? Who the hey knows?

    Hmmm interesting to say the least

    I can only guess that perhaps the electrical charge was like a magnet....pulling it down when it was grounded to the earth?

    Sounds like the nails got melted (or at least heated up to the point that they were pliable), so the force of whatever was hanging from them bent them. But that would have required a) the lightning directly hitting the house and b) heating up the nails (to extreme temperatures)--I don't know whether or not that is reasonable. I suppose it's possible that the path of the charge (electrons) from the lightning could have gone through the nails (more so than other materials) which would have put the nails under an immense current which is capable of melting the nails (or at least heating to the point they would bend).

    ...so frankly, I have no idea--the above is just a guess.

    A thunderclap is a sonic boom with more than

    enough energy to make a wood frame house shake

    and quake. A rapid upward movement of the floor

    (possibly due to resonance) would add to the "g"

    force of objects hung from nails.

    A "16d" nail is hard to imagine for picture hanging.

    Never the less, these nails are soft steel, and assuming you

    are support 10kg or more, could easily bend from

    the thunder clap.
