Hawaii hotspot
Hawaiian volcanoes are characterized by frequent rift eruptions, their large size (thousands of cubic kilometers in volume), and their rough, decentralized shape. Rift zones are a prominent feature on these volcanoes, and account for their seemingly random volcanic structure. The tallest mountain in the Hawaii chain, Mauna Kea, rises above mean sea level. Measured from its base on the seafloor, it is the world's tallest mountain, at ; Mount Everest rises above sea level. Hawaii is surrounded by a myriad of seamounts; however, they were found to be unconnected to the hotspot and its volcanism. Kīlauea has erupted continuously since 1983 through Puʻu ʻŌʻō, a minor volcanic cone, which has become an attraction for volcanologists and tourists alike.
Puʻu Kukui
Puu Kukui is a mountain peak in Hawaii. It is the highest peak of Mauna Kahalawai (the West Maui Mountains). The summit rises above the Puu Kukui Watershed Management Area, an private nature preserve maintained by the Maui Land & Pineapple Company. The peak was formed by a volcano whose caldera eroded into what is now Īao Valley.
