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 last analogue site used by NASA is at Mauna Kea on the Big Island of Hawaii, after which an analogue base under the name of HI-SEAS was founded on Mauna Loa. In total, six NASA missions have started in this base between 2013 and 2018, until the sixth HI-SEAS mission was halted due to a medical emergency.
It is difficult to determine the original size and shape of the volcano, as the southeast flank has been buried by volcanic lava flows from nearby Mauna Kea and Mauna Loa. [ 1 ] [ 4 ] However, based on a sharp increase of incline on the submarine slope of the volcano at a depth of 1,000 m (3,300 ft), scientists estimate that in its prime the ...
Mauna Kea on the Island of Hawaiʻi is the highest peak in the U.S. State of Hawaiʻi and the entire Pacific Ocean. The Hawaiian Islands and the U.S. State of Hawaiʻi 13 major mountain peaks [a] with at least 500 meters (1640 feet) of topographic prominence. The summit of a mountain or hill may be measured in three principal ways:
Mauna Kea is the tallest volcano in the Hawaiian–Emperor seamount chain. Many cinder cones have been emplaced around its summit. Hualalai is a massive shield volcano in the Hawaiian–Emperor seamount chain. Its last eruption was in 1801.
3-D perspective view of the southeastern Hawaiian Islands, with the white summits of Mauna Loa (4,170 m or 13,680 ft high) and Mauna Kea (4,206 m or 13,799 ft high). The evolution of Hawaiian volcanoes occurs in several stages of growth and decline.
The lava can overflow the fissure and form ʻaʻā or pāhoehoe style of flows. When such an eruption from a central cone is protracted, it can form lightly sloped shield volcanoes, for example Mauna Loa or Skjaldbreiður in Iceland. Geologists can predict where new eruptions will take place by tracking the earthquakes that precede the ...
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 ...
