Hawaii Information
Map of the Hawaiian islands
Hawaii is the newest of the 50 U.S. states (August 21, 1959), and is the only U.S. state made up entirely of islands. It is the northernmost island group in Polynesia, occupying most of an archipelago in the central Pacific Ocean, southwest of the continental United States, southeast of Japan, and northeast of Australia. Hawaii’s natural and diverse scenery, warm tropical climate, abundance of public beaches and oceanic surrounding, and active volcanoes make it a popular destination for tourists, surfers, biologists, and volcanologists alike.
Due to its mid-Pacific location, Hawaii has many North American and Asian influences along with its own vibrant native culture. Hawaii has over a million permanent residents along with many visitors and U.S. military personnel. Its capital is Honolulu on the island of Oʻahu.
The 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” to avoid confusion with the state as a whole. The archipelago is physiographically and ethnologically part of the Polynesian subregion of Oceania.
After Alaska, Florida, and California, Hawaii has the fourth-longest coastline in the United States, which is approximately 750 miles (1,210 km) long. In standard American English, Hawaii is generally pronounced /həˈwaɪ.iː/. In the Hawaiian language, it is generally pronounced or ” Havaii”. Hawaii is one of two states that do not observe daylight saving time, the other being Arizona.
Geology
All the Hawaiian islands were formed from volcanic activity initiated at an undersea magma source called a hotspot. As the tectonic plate beneath much of the Pacific Ocean moves to the northwest, the hot spot remains stationary, slowly creating new volcanoes. Due to the hotspot’s location, the only active volcanoes are located around the southern half of the Big Island. The newest volcano, Lōʻihi Seamount, is located south of the Big Island’s coast.
The last volcanic eruption outside the Big Island occurred at Haleakalā on Maui before the late 18th century, though it could have been hundreds of years earlier. In 1790, Kīlauea exploded with the deadliest eruption (of the modern era) known to have occurred in what is now the United States. As many as 5,405 warriors and their families marching on Kīlauea were killed by that eruption. Volcanic activity and subsequent erosion have created impressive geological features. The Big Island has the third highest point among the world’s islands. Slope instability of the volcanoes has generated damaging earthquakes with related tsunamis, particularly in 1868 and 1975.
Flora and fauna
Because the islands are so far from other land habitats, life before human activity is said to have arrived by the “3 W’s”: wind (carried through the air), waves (brought by ocean currents), and wings (birds, insects, and whatever they brought with them). This isolation, and the wide range of environments (extreme altitude, tropical climate) produced a vast array of endemic flora and fauna (see Endemism in the Hawaiian Islands). Hawaii has more endangered species and has lost a higher percentage of its endemic species than any other U.S. state.
Climate
Sunset in Kona. The colors of the sunset are partly due to vog, a form of air pollution that results when sulfur dioxide and other gases and particles emitted by an erupting volcano react with oxygen and moisture in the presence of sunlight.
Hawaii’s climate is typical for the tropics, although temperatures and humidity tend to be a bit less extreme due to near-constant trade winds from the east. Summer highs are usually in the upper 80s °F, (around 31°C) during the day and mid 70s, (around 24 °C) at night. Winter day temperatures are usually in the low to mid 80s, (around 28 °C) and (at low elevation) seldom dipping below the mid 60s (18 °C) at night. Snow, not usually associated with the tropics, falls at 4,205 metres (13,796 ft) on Mauna Kea and Mauna Loa on the Big Island in some winter months. Snow rarely falls on Haleakala. Mount Waiʻaleʻale, on Kauaʻi, has the second highest average annual rainfall on Earth, about 460 inches (11.7 m). Most of Hawaii has only two seasons: the dry season from May to October, and the wet season from October to April.
Local climates vary considerably on each island, grossly divisible into windward (Koʻolau) and leeward (Kona) areas based upon location relative to the higher mountains. Windward sides face cloud cover, so resorts concentrate on sunny leeward coasts.
Population
As of 2005, Hawaii has an estimated population of 1,275,194, an increase of 13,070, or 1.0%, from the prior year and an increase of 63,657, or 5.3%, since 2000. This includes a natural increase of 48,111 people (that is 96,028 births minus 47,917 deaths) and an increase due to net migration of 16,956 people into the state. Immigration from outside the United States resulted in a net increase of 30,068 people, and migration within the country produced a net loss of 13,112 people. The center of population of Hawaii is located between the two islands of Oʻahu and Molokaʻi.
Hawaii has a de facto population of over 1.3 million due to large military and tourist populations. Oʻahu, nicknamed “The Gathering Place”, is the most populous island (and has the highest population density), with a resident population of just under one million in 597 square miles 1,546 km2), about 1,650 people per square mile (for comparison, New Jersey, which has 8,717,925 people in 7,417 square miles (19,210 km2) is the most-densely populated state with 1,134 people per square mile.)Hawaii’s 1,275,194 people, spread over 6,423 square miles (16,640 km2) (including many unpopulated islands) results in an average population density of 188.6 persons per square mile,which makes Hawaii less densely populated than Ohio and Illinois.
The average projected lifespan of those born in Hawaii in 2000 was 79.8 years (77.1 years if male, 82.5 if female), longer than any other state.U.S. military personnel make up approximately 1.3% of the population in the islands.
Cities and towns
Honolulu is the largest city and capital of Hawaii.
The movement of the Hawaiian royal family from the Big Island to Maui, and subsequently to Oʻahu, explains why population centers exist where they do today. Kamehameha III chose the largest city, Honolulu, as his capital because of its natural harbor, the present-day Honolulu Harbor.
Now the state capital, Honolulu is located along the southeast coast of Oʻahu. The previous capital was Lahaina, Maui and before that Kailua-Kona, Hawaii. Some major towns are Hilo, Kāneʻohe, Kailua, Pearl City, Waipahu, Kahului, Kailua-Kona, Kīhei, and Līhuʻe.
