Italy was a country in southern Europe. Its capital was Rome. It was run by the Italian Prime Minister. During the 2012 apocalypse, Italy was hit by large earthquakes, as well its volcanoes engulfed several areas around the country, which were presumably Mount Etna and Mount Vesuvius.
During a mass prayer, where the Italian Prime Minister and his family were taking place, a large earthquake, a magnitude of 9.0, struckRome. The earthquake caused the St Peter's Basilica to collapse, killing the Italian Prime Minister and his family, as well as various people and the Pope.
After the apocalypse ended, the entire state of Italy is flooded due to a mega-tsunami in the Worldwide Flooding and is rendered uninhabitable.
