(Ma = million years) Map of the Hawaiian Islands and some of the Emperor seamounts showing progression in selected erupted lava ages along the chain (Ma = million years) The Hawaiian–Emperor seamount chain is a series of volcanoes and seamounts extending about 6,200 km (3,900 mi) across the Pacific Ocean .
First prepared in 1974 by Donal Mullineaux and Donald Peterson of the USGS and revised in 1992 for the Island of Hawaiʻi, [1] the maps outline the qualitative hazard posed by lava flows based on the history of lava flow activity on each of the five volcanoes that form the Island of Hawaiʻi and Haleakalā volcano on the island of Maui. Zone 1 ...
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 ...
Hawaiʻi Volcanoes National Park is a national park of the United States located in Hawaii on the island of Hawaii. The park encompasses two active volcanoes: Kīlauea , one of the world's most active volcanoes, and Mauna Loa , the world's largest shield volcano.
The volcanoes on the remaining islands are extinct as they are no longer over the Hawaii hotspot. The Kamaʻehuakanaloa Seamount is an active submarine volcano that is expected to become the newest Hawaiian island when it rises above the ocean's surface in 10,000–100,000 years. [ 21 ]
Before Koʻolau volcano was active, between 3.5 and 2.74 million years ago, Waiʻanae volcano formed the western part of Oʻahu. [71] Koʻolau volcano appears to be unrelated to the Honolulu Volcanics, [6] which are considered to be a separate volcanic system; [58] sometimes the "Kokohead Volcanics" are split off from the Honolulu Volcanics.

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 ...
Hualālai (pronounced [huwəˈlaːlɐi] in Hawaiian) is an active volcano on the island of Hawaiʻi in the Hawaiian Islands. [4] It is the westernmost, third-youngest and the third-most active of the five volcanoes that form the island of Hawaiʻi, following Kīlauea and the much larger Mauna Loa. Its peak stands 8,271 feet (2,521 m) above sea ...
