Mauna Kea ( or ; Hawaiian: [ˈmɐwnə ˈkɛjə]; abbreviation for Mauna a Wākea) is a dormant 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 the state of Hawaiʻi and second-highest peak of an island on Earth. 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 wet prominence is fifteenth in the world among mountains, at 4,207.3 m (13,803 ft); its dry prominence is 9,330 m (30,610 ft). This dry prominence is greater than Mount Everest's height above sea level of 8,848.86 m (29,032 ft), and some authorities have labelled Mauna Kea the tallest mountain in the world, from its underwater base.It is about one million years old and thus passed the most active shield stage of life hundreds of thousands of years ago. In its current post-shield state, its lava is more viscous, resulting in a steeper profile. Late volcanism has also given it a much rougher appearance than its neighboring volcanoes due to construction of cinder cones, decentralization of its rift zones, glaciation on its peak, and weathering by the prevailing trade winds. Mauna Kea last erupted 6,000 to 4,000 years ago and is now thought to be dormant.
