It's wild to see this footage safely behind a monitor. Kind of macabre to ponder but I wonder if the victims of Pompeii had a similar experience. The last we see is a hailstorm of ash and molten lava raining down then signal lost.

iirc, Pompeii was a pyroclastic flow [0], a fast-moving current of hot gas and volcanic matter with speeds between 100-700 km/hr and temperatures up to 1000°C. So, probably something like that, but a lot bigger, faster, and arriving faster from further away.

I was surprised how long the camera lasted getting buried. It'd be a not good end.

i just posted a sister comment to yours about the Mt St Helens explosion, with a picture from 1980, and then i noticed that they are calling (it's a non technical article) what rained down in the photograph onto the camera and photographer "pyroclastic flow" and it looks very similar to what happened here.

This is what a pyroclastic flow looks like.
