Hawaiian–Emperor seamount chain
Kīlauea is one of five subaerial volcanoes that make up the island of Hawaii, created by the Hawaiian hotspot. The oldest volcano on the island, Kohala, is more than a million years old, and Kīlauea, the youngest, is believed to be between 300,000 and 600,000 years of age; Lōʻihi Seamount, on the island's flank, is younger and has yet to breach the surface. Thus Kilauea is the second youngest volcano in the Hawaiian–Emperor seamount chain, a chain of shield volcanoes and seamounts extending from Hawaii to the Kuril–Kamchatka Trench in Russia.
