After which type of natural disaster would pyroclastic flow most likely occur?

yikes can't outrun that! Note to self, Do not visit any areas with possibly active volcanoes !

Randall Stone, I think you might be wrong. Yes there was a pyroclastic flow which did kill an awful lot of people, but it was the ash which covered and smothered the people in the towns and encased their bodies in a mummified state that are on show in the likes of Pompey.

Volcanoes are considered active if there has been anything going on for the last 10,000 years. Yes, 10,000 years seems like a long time...

Tanya, this is open to debate among scientists. Most would not consider a valcano active if it hasn't shown activity within the last 100 years, some would argue 50 years or less. I haven't found any reports suggesting 10,000 years. I think that would be considered "dormant"

I knew the answer because a friend of ours was supposed to be on Mt St Helens

Chosen because of the word pyro, pyromaniac, someone who deliberately starts fires. So pyro, fire flow, no idea what clastic means!

I knew the answer because I graduated high school. I wish that more Americans could say that!

I knew the answer because I've seen the movie Dante's Peak.

StationaryStreet4, Me too! Pierce Brosnan described it in Dante's Peak! Great flick!

humbermaniac, Cozzy 25, Yes, lest we forget.

I wonder if the MCU will use Pyro as a bad Guy when they re boot the X men?

ten thousand years is a long time ,duh

Sandyberry, just few weeks ago. people were killed by volcano erupted on a island off New Zealand s coast. they were site seeing tourists.

Player #3532789, it was gas from the pyroclastic flow that killed the victims of Vesuvius in Pompeii and Herculaneum. The ash fall was actually fairly light, but it did cover the bodies and preserve them. The science behind the deaths is fascinating.

MALICE, yeah I'm with you
