As the 200-degrees heat winds came down the Vesuvio people were immediately "freeze" in their position.
Here you can see the way Romans built their houses.
Had Romans yet troubles with speedsters so they invented "speed pumps" ;-) but maybe this are stones for pedestrians to cross a road.
On the 24th to 25th of August in 79 Vesuvio exploded with the power of 100.000 Hiroshima nukes. The material flew 33 km up nearly the same height Felix Baumgartner made (38.970m).
