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:
Of the 13 major summits of Hawaiʻi, Mauna Kea and Mauna Loa exceed 4000 meters (13,123 feet) elevation, Haleakalā exceeds 3000 meters (9843 feet), Hualalai exceeds 2000 meters (6562 feet), and 11 peaks exceed 1000 meters (3281 feet) elevation.
Four of these peaks rise on the island of Hawaiʻi, two on Maui, two on Kauaʻi, two on Molokaʻi, two on Oʻahu, and one on Lānaʻi.
Of the 13 major summits of Hawaiʻi, Mauna Kea exceeds 4000 meters (13,123 feet) of topographic prominence, Haleakalā exceeds 3000 meters (9843 feet), Mauna Loa exceeds 2000 meters (6562 feet), six peaks are ultra-prominent summits with more than 1500 meters (4921 feet), and eight peaks exceed 1000 meters (3281 feet) of topographic prominence.
Of the 13 major summits of Hawaiʻi, Mauna Kea has 3947 kilometers (2453 miles) of topographic isolation and four peaks exceed 100 kilometers (62.14 miles) of topographic isolation.
Mauna Kea is a dormant shield volcano on the island of Hawaiʻi. 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 multiple peaks that are higher. The peak is about 38 m (125 ft) higher than Mauna Loa, its more massive neighbor. Mauna Kea is unusually topographically prominent for its height: its prominence from sea level is fifteenth in the world among mountains, at 4,207.3 m (13,803 ft); its prominence from under the ocean is 9,330 m (30,610 ft), rivaled only by Mount Everest. This dry prominence is greater than Everest's height above sea level of 8,848.86 m (29,032 ft), and some authorities have labeled Mauna Kea the tallest mountain in the world, from its underwater base. Mauna Kea is ranked 8th by topographic isolation.
Haleakalā, or the East Maui Volcano, is a massive, active shield volcano that forms more than 75% of the Hawaiian Island of Maui. The western 25% of the island is formed by another volcano, Mauna Kahalawai, also referred to as the West Maui Mountains.
