The geological history of Kure is generally similar to Midway, but Kure lies close to what is called the Darwin Point, the latitude north of which the rate of natural reef subsidence and destruction surpasses the rate of reef growth. At approximately 30 million years old, it is the oldest in the Hawaiian Island chain. As Kure continues to be slowly carried along to the northwest by the motion of the Pacific Plate, it will move into waters too cool for coral and coralline algae growth to keep up with isostatic subsidence of the mountain. Currently the atoll is warmed by the pools of water at the ends of the warm Kuroshio Current, keeping it in very comfortable range in winter. Barring unforeseen evolution, it will then begin to join the other volcanic and reef-topped remnants of the Hawaiian-Emperor seamount chain to the northwest, all of which are now seamounts.
