300px The State of Hawaii ( or in English; Hawaiian: Mokuʻāina o Hawaiʻi) is a state in the United States, located on an archipelago in the central Pacific Ocean southwest of the continental United States, southeast of Japan, and northeast of Australia. The state was admitted to the Union on August 21, 1959, making it the 50th state. Its capital is Honolulu on the island of Oahu. The most recent census estimate puts the state's population at 1,283,388.

This state encompasses nearly the entire volcanic Hawaiian Island chain, which comprises hundreds of islands spread over 1,500 miles (2,400 km). At the southeastern end of the archipelago, the eight "main islands" are (from the northwest to southeast) Niʻihau, Kauaʻi, Oʻahu, Molokaʻi, Lānaʻi, Kahoʻolawe, Maui, and Hawaiʻi. The last is by far the largest, and is often called the "Big Island" or "Big Isle" to avoid confusion with the state as a whole. This archipelago is physiographically and ethnologically part of the Polynesian subregion of Oceania.

In standard American English, Hawaii is generally . In the Hawaiian language, it is generally or .

Etymology

The Hawaiian language word Hawaiʻi derives from Proto-Polynesian *Sawaiki, with the reconstructed meaning "homeland"; cognate words are found in other Polynesian languages, including Māori (Hawaiki), Rarotongan (ʻAvaiki), and Samoan (Savaiʻi). (See also Hawaiki).

According to Pukui and Elbert, "Elsewhere in Polynesia, Hawaiʻi or a cognate is the name of the underworld or of the ancestral home, but in Hawaiʻi the name has no meaning."

Topography

An archipelago situated some southwest of the North American mainland, Hawaii is the southernmost state of the United States and the second westernmost state after Alaska. Only Hawaii and Alaska are outside the contiguous United States and do not share a border with any other U.S. state.

Hawaii is the only state of the United States that:

• is not geographically located in North America
• grows coffee
• is completely surrounded by water
• is totally an archipelago
• has a royal palace
• does not have a straight line in its state boundary

Hawaii's tallest mountain, Mauna Kea stands at but is taller than Mount Everest if followed to the base of the mountain—from the floor of the Pacific Ocean, rising about .

All of the Hawaiian islands were formed by volcanoes erupting from the sea floor from a magma source described in geological theory as a hotspot. The theory maintains that as the tectonic plate beneath much of the Pacific Ocean moves in a northwesterly direction, the hot spot remains stationary, slowly creating new volcanoes. This explains why only volcanoes on the southern half of the Big Island, and the Loihi Seamount (Lōʻihi) deep below the waters off its southern coast, are presently active, with Loihi being the newest volcano to form.
