Houston was the most populous city in the U.S state of Texas. It was also the HQ for N.A.S.A.
During the 2012 apocalypse, Houston was hit by massive earthquakes which caused major damage to the city, killing numerous people inhabiting the continent. When the Worldwide Flooding occured, Houston and Texas were then swept by one of the gigantic tsunamis and is submerged underwater, killing the remaining population that weren't picked up.
As a result of the apocalypse, Houston is left uninhabitable from the earthquakes, volcanic eruptions and tsunamis, leaving it with extreme damage.
- Though Houston was never seen or mentioned, it is likely that the city was destroyed along with the rest of the world during the 2012 apocalypse.
