Imagine strolling along a city street in the Ancient Roman city of Pompeii in 79AD. Slaves care for you and you have plenty of chances for amusement. Then, at midday on August 24th things go very, very wrong.

A Time Capsule of Ancient Rome

  • Much of what we know about the eruption of Mount Vesuvius in 79 AD comes from two letters written by Pliny the Younger. In fact, extremely explosive eruptions, such as happened at Vesuvius that day, have been named Plinian eruptions for his vivid descriptions. In a Plinian eruptions an enormous column of gas and ash explodes into the stratosphere and then collapses. Scorching hot flows of ash and rock fly down the volcano after the collapse. This eruption of Mount Vesuvius destroyed Pompeii and was one of the most catastrophic eruptions his history.
