Honolulu was the capital and largest city of the U.S state of Hawaii.
During the 2012 Apocalypse, Honolulu was hit by one of the geological natural disasters which were earthquakes of unprecedented strength and then the Hawaiian Hotspot erupted, resulting in the once famous city of Honolulu to be engulfed entirely of lava. The rest of Hawaii's volcanoes erupted which engulfed the entire islands of Hawaii, rendering them uninhabitable.
The Curtis and Karpov Group discover the islands of Hawaii being consumed by lava when they planned to refuel but were forced to make a water landing in the South China Sea. Honolulu and the Hawaiian Islands were later swept by a mega-tsunami during the Worldwide Flooding.
When the apocalypse ended, the once beautiful Islands of Hawaii and Honolulu, were rendered uninhabitable due to the geological natural disasters and has remained flooded.
