A giant island of earthquake-tsunami debris is floating in the sea and will hit the Hawaiian islands in the months to come, researchers have said, according to CNN.

The vast chunk of debris floating around in the sea includes houses, buildings, automobiles, trees and industrial material.

The debris will hit the Hawaiian islands in about a year's time, researchers at the International Pacific Research Center of the University of Hawaii at Manoa said, showing computer simulations.

The debris island will make a second appearance on the island shores five years later, before it eventually lands up in the Great Pacific Garbage Patch.

The Patch, also known as the Pacific Trash Vortex, is a large area in the Pacific Ocean where the sea-borne trash ends up.
