Burj Khalifa was a large skyscraper located in Dubai. It had a height of 830 meters (2726 ft). It was completed and opened to the public in 2010, becoming the tallest building in the world.
During the 2012 apocalypse, Dubai was hit by massive earthquakes which devastated the city and caused several of its skyscrapers to crumble and collapse. The Burj Khalifa suffered major damage and the entire Dubai was then swept by a megatsunami which had a height of 1500 meters during the Worldwide Flooding, destroying the once tallest skyscraper on Earth.
