Pearl Harbor was a harbor located in Hawaii.
During the 2012 apocalypse, the volcanoes erupted in Hawaii, which caused several of its buildings, landmarks and villages to be engulfed by lava and hot ash. Earthquakes of unprecendented strength, triggered by the Earth's unstable crust and eruptions, caused major damage to Pearl Habor, which eventually caused it to collapse, killing several people and destroying various boats in the harbor. The remains of Pearl Harbor and Hawaii were swept by megatsunamis at the height of 1500 meters when the Worldwide Flooding occurred.
After the apocalypse ended, Pearl Harbor is submerged underwater, left with extreme damage and is rendered uninhabitable.
