Pompeii is the ruined and partially buried Roman town city near modern Naples and Caserta in the Italian region of Campania, in to the territory of the comune of Pompei. Along with the Herculaneum, its sister city, Pompeii was destroyed, and completely buried, during a long catastrophic eruption of the volcano Mount Vesuvius spanning two days in AD 79.The archaeological digs at the site extend to the street level of the 79 volcanic event, deeper digs in older parts of Pompeii and core samples of near by drillings have exposed layers of jumbled sediment is that suggest that the city had suffered from the volcano and other seismic events before then. Three sheets of sediment have been found on top of the lava bedrock that lies below the city and, mixed in with the sediment, archaeologists have found bits of animal bone, pottery shards and plants.
