Ghana is a country located in Africa.
During the 2012 apocalypse, Ghana was hit by massive earthquakes and was swept by a megatsunami during the Worldwide Flooding. It remained flooded for 27 days, until when the global floodwaters began to recede, the entire African continents and its countries had risen, along with Ghana, becoming habitable. This made it, and Africa not to suffer extreme damage.
This allowed the 2012 survivors to begin a new life and rebuild their species, when the Arks set sail for the Cape of Good Hope.
