Flexi Says: The Hawaii hotspot has been active for tens of millions of years. The volcanoes of the Hawaiian Islands formed at this hotspot. The oldest island, Kauai, is the furthest from the hotspot. The Emperor Seamounts to the northwest of Kauai are even older. The youngest, the big island of Hawaii, is on top of the hotspot. The Loihi seamount is currently active beneath the water southeast of the Big Island of Hawaii. One day, the volcano will rise above sea level. Loihi will join the volcanoes of the island or create a new island.
