Kaʻala
Kaala or Mount Kaala (pronounced in Hawaiian) is the highest mountain on the island of Oahu, at . It is a part of the Waianae Range, an eroded shield volcano on the west side of the island. The FAA maintains an active tracking station at the summit, which is closed to the general public and secured by the US Army, which is stationed at the base of the mountain at Schofield Barracks. The tracking station can be clearly seen from afar as a white, domed-shaped structure. Climbing The round-trip hike to the summit is a strenuous effort that typically takes 4-6 hours to complete. Much of the trail is steep, heavily foliaged, narrow, and muddy. Some segments of the trail have ropes and ladders in place due to the steepness and slipperiness. The round-trip hike has a distance of 7 miles (12km) and 3600ft (1100m) in elevation gain. __TOC__ See also *List of mountain peaks of the United States ** List of volcanoes of the United States *** List of mountain peaks of Hawaii * Evoluti ...

List Of Mountain Peaks Of Hawaii
The Hawaiian Islands has 13 major mountain peaks with at least of topographic prominence. The summit of a mountain or hill may be measured in three principal ways: #The topographic elevation of a summit measures the height of the summit above a geodetic sea level.If the elevation or prominence of a summit is calculated as a range of values, the arithmetic mean is shown. The first table below ranks the 13 major summits of Hawaii by topographic elevation. #The topographic prominence of a summit is a measure of how high the summit rises above its surroundings.The topographic prominence of a summit is the topographic elevation difference between the summit and its highest or key col to a higher summit. The summit may be near its key col or quite far away. The key col for Denali in Alaska is the Isthmus of Rivas in Nicaragua, away. The second table below ranks the 13 major summits of Hawaii by topographic prominence. #The topographic isolation (or radius of dominance) of a ...

Shield Volcano
A shield volcano is a type of volcano named for its low profile, resembling a shield lying on the ground. It is formed by the eruption of highly fluid (low viscosity) lava, which travels farther and forms thinner flows than the more viscous lava erupted from a stratovolcano. Repeated eruptions result in the steady accumulation of broad sheets of lava, building up the shield volcano's distinctive form. Shield volcanoes are found wherever fluid, low-silica lava reaches the surface of a rocky planet. However, they are most characteristic of ocean Volcanic island, island volcanism associated with Hotspot (geology), hot spots or with Rift, continental rift volcanism. They include the largest active volcanoes on Earth, such as Mauna Loa. Giant shield volcanoes are found on other planets of the Solar System, including Olympus Mons on Mars and Sapas Mons on Venus. Etymology The term 'shield volcano' is taken from the German term ''Schildvulkan'', coined by the Austrian geologist Eduar ...

Volcanoes Of Oahu
A volcano is commonly defined as a vent or fissure in the crust of a planetary-mass object, such as Earth, that allows hot lava, volcanic ash, and gases to escape from a magma chamber below the surface. On Earth, volcanoes are most often found where tectonic plates are diverging or converging, and because most of Earth's plate boundaries are underwater, most volcanoes are found underwater. For example, a mid-ocean ridge, such as the Mid-Atlantic Ridge, has volcanoes caused by divergent tectonic plates whereas the Pacific Ring of Fire has volcanoes caused by convergent tectonic plates. Volcanoes resulting from divergent tectonic activity are usually non-explosive whereas those resulting from convergent tectonic activity cause violent eruptions."Mid-ocean ridge tectonics, volcanism and geomorphology." Geology 26, no. 455 (2001): 458. https://macdonald.faculty.geol.ucsb.edu/papers/Macdonald%20Mid-Ocean%20Ridge%20Tectonics.pdf Volcanoes can also form where there is stretching an ...

Hawaiian–Emperor Seamount Chain
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 along a line trending southeast to northwest beneath the northern Pacific Ocean. The seamount chain, containing over 80 identified undersea volcanoes, stretches about from the Aleutian Trench off the coast of the Kamchatka peninsula in the far northwest Pacific to the Kamaʻehuakanaloa Seamount (formerly Lōʻihi), the youngest volcano in the chain, which lies about southeast of the Island of Hawaiʻi. Regions The chain can be divided into three subsections. The first, the Hawaiian archipelago (also known as the ''Windward isles''), consists of the islands comprising the U.S. state ...

Hawaii Hotspot
The Hawaii hotspot is a volcanic hotspot located near the namesake Hawaiian Islands, in the northern Pacific Ocean. One of the best known and intensively studied hotspots in the world, the Hawaii plume is responsible for the creation of the Hawaiian–Emperor seamount chain, a mostly undersea volcanic mountain range. Four of these volcanoes are active, two are dormant; more than 123 are extinct, most now preserved as atolls or seamounts. The chain extends from south of the island of Hawaii to the edge of the Aleutian Trench, near the eastern coast of Russia. While some volcanoes are created by geologic processes near tectonic plate convergence and subduction zones, the Hawaii hotspot is located far from plate boundaries. The classic hotspot theory, first proposed in 1963 by John Tuzo Wilson, proposes that a single, fixed mantle plume builds volcanoes that are then cut off from their source by the movement of the Pacific plate. This causes less lava to erupt from these ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Evolution Of Hawaiian Volcanoes
The evolution of Hawaiian volcanoes occurs in several stages of growth and decline. The fifteen volcanoes that make up the eight principal islands of Hawaii are the youngest in a chain of more than 129 volcanoes that stretch across the North Pacific Ocean, called the Hawaiian–Emperor seamount chain. Hawaii's volcanoes rise an average of to reach sea level from their base. The largest, Mauna Loa, is high. As shield volcanoes, they are built by accumulated lava flows, growing a few meters or feet at a time to form a broad and gently sloping shape. Hawaiian islands undergo a systematic pattern of submarine and subaerial growth that is followed by erosion. An island's stage of development reflects its distance from the Hawaii hotspot. Background The Hawaiian–Emperor seamount chain is remarkable for its length and its number of volcanoes. The chain is split into two subsections across a break, separating the older Emperor Seamount Chain from the younger Hawaiian Ridge; the V ...

Schofield Barracks
Schofield Barracks is a United States Army installation and census-designated place (CDP) located in Honolulu and in the Wahiawa District of the Hawaiian island of Oahu, Hawaii. Schofield Barracks lies adjacent to the town of Wahiawā, separated from most of it by Lake Wilson (also known as Wahiawā Reservoir). Schofield Barracks is named after Lieutenant General John McAllister Schofield, who was the Commanding General of the United States Army from August 1888 to September 1895. He had been sent to Hawaii in 1872 and had recommended the establishment of a naval base at Pearl Harbor. Schofield Barracks has an area of on Central Oahu. The post was established in 1908 to provide mobile defense of Pearl Harbor and the entire island. It has been the home of the 25th Infantry Division, nicknamed the "Tropic Lightning" division, since 1941, as well as the headquarters for United States Army Hawaii (USARHAW). Schofield is home to the Pacific field office of the Army CID. The popu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mountain
A mountain is an elevated portion of the Earth's crust, generally with steep sides that show significant exposed bedrock. Although definitions vary, a mountain may differ from a plateau in having a limited summit area, and is usually higher than a hill, typically rising at least above the surrounding land. A few mountains are inselberg, isolated summits, but most occur in mountain ranges. mountain formation, Mountains are formed through tectonic plate, tectonic forces, erosion, or volcanism, which act on time scales of up to tens of millions of years. Once mountain building ceases, mountains are slowly leveled through the action of weathering, through Slump (geology), slumping and other forms of mass wasting, as well as through erosion by rivers and glaciers. High elevations on mountains produce Alpine climate, colder climates than at sea level at similar latitude. These colder climates strongly affect the Montane ecosystems, ecosystems of mountains: different elevations hav ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hawaiian Language
Hawaiian (', ) is a critically endangered Polynesian language of the Austronesian language family, originating in and native to the Hawaiian Islands. It is the native language of the Hawaiian people. Hawaiian, along with English, is an official language of the U.S. state of Hawaii. King Kamehameha III established the first Hawaiian-language constitution in 1839 and 1840. In 1896, the Republic of Hawaii passed Act 57, an English-only law which subsequently banned Hawaiian language as the medium of instruction in publicly funded schools and promoted strict physical punishment for children caught speaking the Hawaiian language in schools. The Hawaiian language was not again allowed to be used as a medium of instruction in Hawaii's public schools until 1987, a span of 91 years. The number of native speakers of Hawaiian gradually decreased during the period from the 1830s to the 1950s. English essentially displaced Hawaiian on six of seven inhabited islands. In 2001, native ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
