Pompeii

Pompeii is a Roman city that was covered by the ash of the volcano of Vesuvius after it erupted in 79 AD. The city was undiscovered until 1700. Archaeologists began clearing the ash away to find the perfectly preserved city. Even the expressions on the faces of the civilians watching the ash pour down on them could still be seen! Vesuvius hadn't erupted 1800 years so the eruption was massive. There wasn't a usual eruption with lava, this eruption was just ash and rock. There was so much ash that it completely covered two cities! While the ash was coming down over the land there were also rocks falling from the sky called pumice. The eruption was just under 24 hours long and in this time more than 4 cubic kilometers of material came out of Vesuvius!
