... I hope no one was injured. They must have evacuated vulnerable areas, don't you think?

fleeing the scene, foot to the metal! Knowing about what a pyroclastic cloud can do, I would be right behind him!

... moving at more than a hundred miles per hour. I would NOT want to be trying to outrun one of those!

close enough, you are dead.

A pyroclastic flow (also known scientifically as a pyroclastic density current) is a fast-moving current of hot gas and rock (collectively known as tephra), which reaches speeds moving away from a volcano of up to 700 km/h (450 mph). The gas can reach temperatures of about 1,000 °C (1,830 °F).

Oh! The video didn't show up right away (Slow DSL today) That is horrifying! 43 dead in a matter of seconds. Glad I don't live on top of the Pacific "Ring of Fire." Damn...
