Wailuku River
The Wailuku River is a U.S. Geological Survey. National Hydrography Dataset high-resolution flowline dataThe National Map, accessed April 28, 2011 water course on the Island of Hawaii in the Hawaiian Islands. It is the longest river in Hawai'i and the largest in the state by mean discharge. Its course lies mostly along the divide between the lava flows of Mauna Kea and those of Mauna Loa to the south. It arises at about the elevation along the eastern slope of Mauna Kea (). It flows generally eastward, descending steeply from the mountain and entering the Pacific Ocean at Hilo. Wailuku River State Park is located along the lower reach of the river. One section of the park includes Rainbow Falls (), and another section Peepee falls and an area called the Boiling Pots (a series of small falls and pools). However, it is also one of the deadliest bodies of water in the state, as the river is not guarded and can behave unpredictably. The lower reach of the river is used for the g ...

Wailuku River State Park
Wailuku is a census-designated place (CDP) in and county seat of Maui County, Hawaii, United States. The population was 17,697 at the 2020 census. Wailuku is located just west of Kahului, at the mouth of the Iao Valley. In the early 20th century Wailuku was the main tourist destination on Maui, though it has since been eclipsed with the rise of the resort towns such as Kaanapali. Historic sites in the town include Kaʻahumanu Church (named after Queen Kaʻahumanu, wife of Kamehameha I) which dates to 1876, the Wailuku Civic Center Historic District, the site of the Chee Kung Tong Society Building, and the Bailey House, a 19th-century former seminary and home that houses a history museum and the Maui Historical Society. There are two ancient temples near Wailuku, called — the Halekiʻi Heiau and the Pihanakalani Heiau. Both date back hundreds of years and were used for religious purposes by the native Hawaiians.

Hawaiian Language
Hawaiian (', ) is a Polynesian language of the Austronesian language family that takes its name from Hawaii, the largest island in the tropical North Pacific archipelago where it developed. Hawaiian, along with English, is an official language of the US state of Hawaii. King Kamehameha III established the first Hawaiian-language constitution in 1839 and 1840. For various reasons, including territorial legislation establishing English as the official language in schools, the number of native speakers of Hawaiian gradually decreased during the period from the 1830s to the 1950s. Hawaiian was essentially displaced by English on six of seven inhabited islands. In 2001, native speakers of Hawaiian amounted to less than 0.1% of the statewide population. Linguists were unsure if Hawaiian and other endangered languages would survive. Nevertheless, from around 1949 to the present day, there has been a gradual increase in attention to and promotion of the language. Public Hawaiian-lang ...

Hydroelectricity
Hydroelectricity, or hydroelectric power, is electricity generated from hydropower (water power). Hydropower supplies one sixth of the world's electricity, almost 4500 TWh in 2020, which is more than all other renewable sources combined and also more than nuclear power. Hydropower can provide large amounts of low-carbon electricity on demand, making it a key element for creating secure and clean electricity supply systems. A hydroelectric power station that has a dam and reservoir is a flexible source, since the amount of electricity produced can be increased or decreased in seconds or minutes in response to varying electricity demand. Once a hydroelectric complex is constructed, it produces no direct waste, and almost always emits considerably less greenhouse gas than fossil fuel-powered energy plants.

Rainbow Falls (Hawaii)
Rainbow (Waiānuenue) Falls is a waterfall located in Hilo, Hawaii. It is tall and almost in diameter. The falls are part of the Hawai'i State Parks. There is no fee to see the falls. At Rainbow (Waiānuenue) Falls, the Wailuku River rushes into a large pool below. The gorge is blanketed by lush, dense nonnative tropical rainforest and the turquoise-colored pool is bordered by beautiful, although nonnative, wild ginger. Monstera is also in abundance. The falls are accessible via Wailuku River State Park, Waiānuenue Avenue, coordinates , and are best seen from the park's viewing platform. Known in the Hawaiian language as Waiānuenue (literally "rainbow water"), the falls flows over a natural lava cave, the mythological home to Hina, an ancient Hawaiian goddess. Rainbow Falls derives its name from the fact that, on sunny mornings around 10am, rainbows can be seen in the mist thrown up by the waterfall.

Hawaii
Hawaii ( ; haw, Hawaii or ) is a state in the Western United States, located in the Pacific Ocean about from the U.S. mainland. It is the only U.S. state outside North America, the only state that is an archipelago, and the only state geographically located within the tropics. Hawaii comprises nearly the entire Hawaiian archipelago, 137 volcanic islands spanning that are physiographically and ethnologically part of the Polynesian subregion of Oceania. The state's ocean coastline is consequently the fourth-longest in the U.S., at about . The eight main islands, from northwest to southeast, are Niihau, Kauai, Oahu, Molokai, Lānai, Kahoolawe, Maui, and Hawaii—the last of these, after which the state is named, is often called the "Big Island" or "Hawaii Island" to avoid confusion with the state or archipelago. The uninhabited Northwestern Hawaiian Islands make up most of the Papahānaumokuākea Marine National Monument, the United States' largest protected area a ...

Mauna Loa
Mauna Loa ( or ; Hawaiian: ; en, Long Mountain) is one of five volcanoes that form the Island of Hawaii in the U.S. state of Hawaii in the Pacific Ocean. The largest subaerial volcano (as opposed to subaqueous volcanoes) in both mass and volume, Mauna Loa has historically been considered the largest volcano on Earth, dwarfed only by Tamu Massif. It is an active shield volcano with relatively gentle slopes, with a volume estimated at , although its peak is about lower than that of its neighbor, Mauna Kea. Lava eruptions from Mauna Loa are silica-poor and very fluid, and tend to be non-explosive. Mauna Loa has probably been erupting for at least 700,000 years, and may have emerged above sea level about 400,000 years ago. The oldest-known dated rocks are not older than 200,000 years. The volcano's magma comes from the Hawaii hotspot, which has been responsible for the creation of the Hawaiian island chain over tens of millions of years. The slow drift of ...

Lava
Lava is molten or partially molten rock (magma) that has been expelled from the interior of a terrestrial planet (such as Earth) or a moon onto its surface. Lava may be erupted at a volcano or through a fracture in the crust, on land or underwater, usually at temperatures from . The volcanic rock resulting from subsequent cooling is also often called ''lava''. A lava flow is an outpouring of lava during an effusive eruption. (An explosive eruption, by contrast, produces a mixture of volcanic ash and other fragments called tephra, not lava flows.) The viscosity of most lava is about that of ketchup, roughly 10,000 to 100,000 times that of water. Even so, lava can flow great distances before cooling causes it to solidify, because lava exposed to air quickly develops a solid crust that insulates the remaining liquid lava, helping to keep it hot and inviscid enough to continue flowing. The word ''lava'' comes from Italian and is probably derived from the Latin word ''labes ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
