Cleanup begins after eruption at Mt Aso in southwestern Japan

It's over. お疲れ様

Pyroclastic flows are enormously dangerous, more so than lava flows as they move far faster than you can outrun them even in a car (despite what Hollywood would have you believe) and can travel considerable distances. They are what destroyed Herculaneum and Pompeii and if Mount St Helen had been near a town or city we would have a modern Pompeii. Luckily it wasn’t.

Pyroclastic flows are enormously dangerous

I think many will remember the 1991 Mount Unzen pyroclastic flow in Kyushu that killed 43 people.

Cleaning up after Aso mess. Not the last time this will need to be done.

I hope Pan-kun is ok ^^
