    I believe that’s Mt St Helens erupting. Real footage from 1980 (though this gif is sped up).

        Mt, St. Helen compared to Yellowstone or the Phlegraean Fields in Italy was an a simple New Year’s Eve rocket. Both capable to create an month long night on the whole Earth.

        The Yellowstone volcano is about 8 times larger than the entirety of park that has Mt St Helens in it (~860,000 acres of volcano vs ~110,000 acres of park).

        It’s neat seeing someone learn about Mt St Helen’s for the first time. It was such a big deal in the 80s that I can’t remember not knowing about it. It makes me excited to discover major events I know nothing about…

        Anyway… The thing with it wasn’t necessarily the size of the eruption. There have been much, much bigger eruptions. It’s that it was one of the first with really good footage (since it was one of the earlier predicted eruptions), it occurred in the US, and it blew out sideways instead of the top.

      If I recall correctly, it is not real “footage” but real photos which are interpolated into a film using editing software

        That would definitely explain why it’s sped up if the source was a bunch of still images. I’ve seen other edits of it that look a little more like a real-time video.
