On this date in 79 A.D., Mount Vesuvius shook southern Italy and boiled over into one of the most devastating volcanic eruptions in history. Since then, the mountain has erupted more than 50 times.
The eruption 1,930 years ago buried the ancient cities of Pompeii and Herculaneum with hot ash. The ash preserved the cities just as they were at the time of eruption. Excavators even found an oven that still contained loaves of bread almost 2,000 years old.
