During the 2012 Apocalypse, Italy was hit by massive earthquakes, devastating the country and killing millions. Its volcanoes also erupted and engulfed several regions around the country.
During a mass prayer, where the Italian Prime Minister and his family were taking place, a large earthquake in a magnitude of 9.1 struck Rome. The earthquake caused the St Peter's Basilica to collapse, killing the Italian Prime Minister and his family, as well as the Pope and everyone else in the vicinity. The remains of the ruined Italy were swept by a megatsunami at the height of 1500 meters in the Worldwide Flooding.
After the apocalypse ended, a large portion of Italy was submerged underwater, but is later arose with other landmasses and is presumed to be rendered habitable.
