AVALANCHE
OF FIRE
POMPEII
Mount Vesuvius in Italy is one of the world’s most
dangerous volcanoes. This was proved nearly 2,000 years
ago, when an explosive eruption hurled a vast cloud of
volcanic gas and ash high into the sky. As people ran for
their lives, parts of the ash cloud collapsed and surged
downhill in high-speed avalanches of lethally hot gas
and rock. These pyroclastic flows overwhelmed the
nearby cities of Pompeii and Herculaneum, killing
thousands of people within seconds, and burying
them in deep layers of ash.
