On August 24, 79 A.D., Vesuvius suddenly returned to life. The mountain erupted violently, shooting a column of pyroclastic material, gas, and rock up to twenty miles into the sky. The tremendous cloud of material quickly spread out, blocking the sun and turning the bright summer day into night. The eruption continued for at least three days. During this whole time, pyroclastic material fell on Pompeii. The town was buried by volcanic ash and other material. In places the ash, which is called a volcanic fallout deposit, was more than ten feet thick. The city of Pompeii was buried and forgotten.


Plaster casts of people trying to protect themselves from the hot ash that incinerated their bodies.
