Have you heard about Pompeii? Do you know what did happen to this city?. In fact Pompeii was one of the largest Roman city, which has been completely buried in a great volcanic ash following the eruption of nearby Mt. Vesuvius in 79 CE. The ash that came from the eruption was about hundreds of feet and for 18 hours, which destroyed everything on its way.
This disaster made the city abandoned and killed all the people who lived there. Buried bodies have been discovered under 9 meters below the Earth. Some of the archaeological have covered the dead bodies with plaster casts to preserve them for long time. But nowadays they have found a new way to preserve the bodies.
