Portugal was a country in Europe and its capital was Lisbon.
During the 2012 apocalypse, Portugal was hit by massive earthquakes, destroying various cities and killing several people living in the country. Volcanoes erupted in Europe which caused Portugal to be covered in ash and engulfed by pyroclastic flows. The remains of the ruined Portugal were then swept by a megatsunami at the height of 1500 meters in the Worldwide Flooding.
As a result of the apocalypse, Portugal is left with extreme damage and is submerged underwater. When the global floodwaters started to recede, most of Europe had risen and presumably Portugal, but it is unknown if it is habitable.
