what is the tallest volcano in hawaiian islands
Mauna Kea Mauna Kea (/ˌmɔːnə ˈkeɪ.ə/ or /ˌmaʊnə ˈkeɪ.ə/, Hawaiian: [ˈmɐwnə ˈkɛjə]), is a dormant volcano on the island of Hawaii. Standing 4,207 m (13,802 ft) above sea level, its peak is the highest point in the state of Hawaii making the island of Hawaii the second highest island in the world. Most of the mountain is underwater; when measured from its oceanic base, Mauna Kea is over 10,000 m (33,000 ft) tall and is the tallest mountain on Earth.[5] Mauna Kea is about a million years old, and has 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; contributing factors include the construction of cinder cones, the decentralization of its rift zones, the glaciation on its peak, and the weathering effects of the prevailing trade winds. Mauna Kea last erupted 6,000 to 4,000 years ago and is now considered dormant.
Kīlauea On May 17, 2018 at 4:17 AM, the volcano explosively erupted at the summit in Halemaumau Crater, throwing ash 30,000 feet into the air.[4] Summit explosions have caused the long-term closure of the KÄ«lauea section of Hawaii Volcanoes National Park, and vigorous eruptive activity is ongoing in lower Puna, where lava entered the ocean in three places, destroyed Hawaii's largest freshwater lake, covered substantial portions of Leilani Estates and Lanipuna Gardens, completely inundated Vacationland Hawaii and all but three houses in the Kapoho Beach Lots. Lava also filled Kapoho Bay and extended new land nearly a mile into the sea.[5][6] The total number of houses taken by lava since May 3, 2018 was officially announced on June 7 as approximately 600.[7][8] On July 9 the official total had increased to 700 houses.[9]
