Mauna Kea (/ ˌ m ɔː n ə ˈ k eɪ ə, ˌ m aʊ n ə-/, [6] Hawaiian: [ˈmɐwnə ˈkɛjə]; abbreviation for Mauna a Wākea) [7] is a dormant shield volcano on the island of Hawaiʻi. [8] Its peak is 4,207.3 m (13,803 ft) above sea level, making it the highest point in Hawaii and the island with the second highest high point, behind New Guinea, the world's largest tropical island with ...
The Hawaiian–Emperor seamount chain is a mostly undersea mountain range in the Pacific Ocean that reaches above sea level in Hawaii.It is composed of the Hawaiian ridge, consisting of the islands of the Hawaiian chain northwest to Kure Atoll, and the Emperor Seamounts: together they form a vast underwater mountain region of islands and intervening seamounts, atolls, shallows, banks and reefs ...
The southeast rift zone passes under the nearby Mauna Kea and reappears further southeast in the Hilo Ridge, as indicated by the relationship between collected lava samples. In addition, the two features align to one another more closely than does the ridge to Mauna Kea, of which it was once thought to constitute a part.
Mauna Kea is relatively close to its submerged key col in the Pacific Ocean, and the corresponding contour line that surrounds Mauna Kea is a relatively compact area of the ocean floor. Whereas a contour line around Everest that is lower than 9330m from Everest's peak would surround most of the major continents of the Earth.
Everest is highest from sea level (green), Mauna Kea is highest from its base (orange), Cayambe is farthest from Earth's axis (pink) and Chimborazo is farthest from Earth's centre (blue) Heights of mountains are typically measured above sea level. Using this metric, Mount Everest is the highest mountain on Earth, at 8,848 metres (29,029 ft). [73]
Based in Hilo, Hawaii, the observatory monitors six Hawaiian volcanoes: Kīlauea, Mauna Loa, Kamaʻehuakanaloa (formerly Lōʻihi), Hualālai, Mauna Kea, and Haleakalā, of which, Kīlauea and Mauna Loa are the most active. The observatory has a worldwide reputation as a leader in the study of active volcanism.
When Hawaii’s Mauna Loa, the world’s largest active volcano, erupted this week for the first time in almost four decades, it wasn’t just a major geological
