Michigan was a state in the United States.
During the 2012 apocalypse, Michigan was hit by massive earthquakes, destroying many of its buildings, places, towns, villages and landmarks, killing numerous people living in the state. The state was presumably hit by the Yellowstone Ash Cloud when it began to spread around the U.S and Canada, engulfing it. The ruined and devastated Michigan was then swept by a megatsunami at the height of 1500 meters in the Worldwide Flooding.
After the apocalypse ended, Michigan is left with extreme damage and is rendered uninhabitable.
