Hurricane Walaka, the second-strongest tropical cyclone in the Pacific — alongside Hurricane Gilma in 1994 — washed away most of East Island, one of the Northwestern Hawaiin islands, in October last year.
It may not be the biggest island as an 11-acre strip of sand, but it was one of the most significant coral reef systems in the area. It was also the nesting ground for the threatened species of Hawaiin green turtles and endangered monk seals.
It's unclear if the island will reappear, and scientists expect future hurricanes to be stronger and wetter due to climate change.
