And yet protagonists survive after going through a pyroclastic flow routinely in the movies, such as Jurassic World: FK and 2012. It is a recurring trope in movies!

Even the good ones are not very scientifically accurate, tbh.
I don't care, as long as none of them challenge the way to escape an exploding volcano involves parkour and beating up/shooting bad guys while doing so.
