Maui, Hawaii, United States

Geology and topography

🇺🇸 The island of Maui is the second-largest of the Hawaiian Islands and is the 17th largest island in the United States. Maui is part of the State of Hawaii and is the largest of Maui County's four islands, which include Molokaʻi, Lānaʻi, and unpopulated Kahoʻolawe. Maui has the third-highest of the Hawaiian Islands. Kahului is the largest place on the island, and is the commercial and financial hub of the island. Wailuku is the seat of Maui County and is the third-largest CDP as of 2010. Other significant places include Kīhei, Lāhainā, Makawao, Pukalani, Pāʻia, Kula, Haʻikū, and Hāna.

Geology and topography Maui's diverse landscapes are the result of a unique combination of geology, topography, and climate. Each volcanic cone in the chain of the Hawaiian Islands is built of dark, iron-rich/quartz-poor rocks, which poured out of thousands of vents as highly fluid lava throughout millions of years. Several of the volcanoes were close enough to each other that lava flows on their flanks overlapped one another, merging into a single island. Maui is such a "volcanic doublet", formed from two shield volcanoes that overlapped one another to form an isthmus between them.

The older, western volcano has been eroded considerably and is cut by numerous drainages, forming the peaks of the West Maui Mountains (in Hawaiian, Mauna Kahalawai). Puʻu Kukui is the highest of the peaks at 5,788 ft (1,764 m). The larger, younger volcano to the east, Haleakalā, rises to more than 10,000 ft (3,000 m) above sea level, and measures 5 mi (8.0 km) from seafloor to summit.

The eastern flanks of both volcanoes are cut by deeply incised valleys and steep-sided ravines that run downslope to the rocky, windswept shoreline. The valley-like Isthmus of Maui that separates the two volcanic masses was formed by sandy erosional deposits.

Maui's last eruption (originating in Haleakalā's Southwest Rift Zone) occurred around 1790; two of the resulting lava flows are located (1) at Cape Kīnaʻu between ʻĀhihi Bay and La Perouse Bay on the south-west shore of East Maui, and (2) at Makaluapuna Point on Honokahua Bay on the north-west shore of West Maui. Considered to be dormant by volcanologists, Haleakalā is certainly capable of further eruptions.

Maui is part of a much larger unit, Maui Nui, that includes the islands of Lānaʻi, Kahoʻolawe, Molokaʻi, and the now submerged Penguin Bank. During periods of reduced sea level, including as recently as 200,000 years ago, they are joined as a single island due to the shallowness of the channels between them.
