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

    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.

    Thank you, I just read the Wikipedia summary of the event, and I can’t believe this isn’t even as big as the “Big One” everyone talks about for Yellowstone.

      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.

        Haha, yea, I wasn’t even born in the right decade on the right continent to know about this, so I had a really good time learning about something new!

        The only reason I know about the Yellowstone caldera eruption zone is because my American cousin once told me about it in the form of a horror story when we were both younger, and I started crying because I thought the world was going to end while we were visiting Connecticut, lol.

      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).

        And burying entire states 2m (~6’) deep in ash and stone

  Mt. St. Helen’s eruption, 1980. I remember this form when I was a kid. I couldn’t wrap my head around a mountain exploding then, and I still can’t.

  Where is this from?? Is this AI?

  At this point in Earth’s timeline (1980) AI had not yet gained control of Earth’s volcanoes through a projection network of 80s music into the asthenosphere.
