The Sound Heard Around the World?

[Blansky]

"A volcano on Krakatoa had just erupted with a force so great that it tore the island apart, emitting a plume of smoke that reached 17 miles into the atmosphere, according to a geologist who witnessed it. You could use this observation to calculate that stuff spewed out of the volcano at over 1,600 miles per hour—or nearly half a mile per second. That’s more than twice the speed of sound."

I remember in 1980 when Mount Saint Helens blew, our lawn was covered in ash 600 miles away.

It was like dirty snow.

I was driving through the Painted Desert in Arizona a few days later and you couldn’t see 10 feet in front of you.
