Aleutian Islands
The Aleutian Islands (; ; ale, Unangam Tanangin,”Land of the Aleuts", possibly from Chukchi language, Chukchi ''aliat'', "island"), also called the Aleut Islands or Aleutic Islands and known before 1867 as the Catherine Archipelago, are a chain of 14 large volcanic islands and 55 smaller islands. Most of the Aleutian Islands belong to the U.S. state of Alaska, but some belong to the Russian Federal subjects of Russia, federal subject of Kamchatka Krai. They form part of the Aleutian Arc in the Northern Pacific Ocean, occupying a land area of 6,821 sq mi (17,666 km2) and extending about westward from the Alaska Peninsula toward the Kamchatka Peninsula in Russia, and act as a border between the Bering Sea to the north and the Pacific Ocean to the south. Crossing 180th meridian, longitude 180°, at which point east and west longitude end, the archipelago contains both the westernmost part of the United States by longitude (Amatignak Island) and the easternmost by longitude ( ...

Island
An island (or isle) is an isolated piece of habitat that is surrounded by a dramatically different habitat, such as water. Very small islands such as emergent land features on atolls can be called islets, skerries, cays or keys. An island in a river or a lake island may be called an eyot or ait, and a small island off the coast may be called a holm. Sedimentary islands in the Ganges delta are called chars. A grouping of geographically or geologically related islands, such as the Philippines, is referred to as an archipelago. There are two main types of islands in the sea: continental and oceanic. There are also artificial islands, which are man-made. Etymology The word ''island'' derives from Middle English ''iland'', from Old English ''igland'' (from ''ig'' or ''ieg'', similarly meaning 'island' when used independently, and -land carrying its contemporary meaning; cf. Dutch ''eiland'' ("island"), German ''Eiland'' ("small island")). However, the spelling of the word ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Islands Of Four Mountains
Islands of Four Mountains (russian: Четырёхсопочные острова) is an island grouping of the Aleutian Islands in Alaska, United States. The chain includes, from west to east, Amukta, Chagulak, Yunaska, Herbert, Carlisle, Chuginadak, Uliaga, and Kagamil islands. This island chain is located between Amukta Pass and the Andreanof Islands to the west, and Samalga Pass and the Fox Islands to the east. These islands have a total land area of 210.656 sq mi (545.596 km2) and have no permanent population. The two largest islands are Yunaska and Chuginadak. Chuginadak is mainly made up of the active volcano Mount Cleveland. The name is translated from Russian Четырехсопочные Острова (Ostrova Chetyre Soposhnye) meaning "Islands of Four Volcanoes" (Sarichev, 1826, map 3). The early Russian explorers named the islands by this term because of four prominent volcanoes, each located on a separate island. The Aleut name ''Unigun'' (Uniiĝun ...

Fox Islands (Alaska)
The Fox Islands (russian: Лисьи острова) are a group of islands in the eastern Aleutian Islands of the U.S. state of Alaska. The Fox Islands are the closest to mainland North America in the Aleutian chain, and just east of Samalga Pass and the Islands of Four Mountains group. Inhabited by the Aleut for centuries, the islands, along with the rest of the Aleutians, were first visited by Europeans in 1741, when a Danish navigator employed by the Imperial Russian Navy, Vitus Bering, was searching for new sources of fur for Russian fur trappers. Foggy almost all year round, the islands are difficult to navigate due to constantly adverse weather and numerous reefs. The Fox Islands Passes are the waterways surrounding the islands. As with the other Aleutian islands, the Fox Islands are prone to frequent earthquakes year-round. The larger Fox Islands are, from west to east, Umnak, Unalaska, Amaknak, Akutan, Akun, Unimak and Sanak. Islands lying west of Akutan are in ...

Seguam Island
Seguam Island ( ale, Saĝuugamax; russian: Остров Сигуам) is a small volcanic island in the Andreanof Islands group in the Aleutian Islands of Alaska. The island is mountainous and oval shaped with a land area of . It is long and wide. The 2000 census reported a population of one person. The island consists of several overlapping stratovolcanoes, and it contains two calderas each with central volcanic cones. About 10 historical eruptions have been recorded since the late 18th century, the most recent in 1993. All recent activity has occurred at Pyre Peak, the cone within the western caldera and the highest point on the island, and has produced explosive eruptions and basaltic lava flow 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.

Chagulak Island
Chagulak Island (also spelled ''Chugul'', ''Chugula'', ''Chegoula'', or ''Tchougoulok''; russian: Чагулак) is a small, uninhabited volcanic island in the Islands of Four Mountains group in the Aleutian Islands of southwestern Alaska, United States. The -wide island consists of a single cone that reaches an elevation of 3,747 ft (1,142 m). Chagulak is a stratovolcano and is separated from the nearby Amukta Island by a channel about wide; though the two islands are joined underwater. No eruptions have been recorded and very little is known about the volcano, as the only study done on Chagulak so far is a single chemical analysis of a "low-potassium, high-alumina basaltic andesite Basaltic andesite is a volcanic rock that is intermediate in composition between basalt and andesite.

Mount Amukta
The undissected stratovolcano of Amukta volcano makes up most of nearly circular, 7.7-km-wide Amukta Island (Amuux̂tax̂ in Aleut). It is the westernmost of the Islands of Four Mountains chain. The cone, about 5.8 km in basal diameter and topped by a 0.4 km wide summit crater, appears on synthetic-aperture radar imagery to be built upon a 300+ meter high, east-west trending arcuate ridge. Extensions of that ridge on the southwest and east sides of the island indicate an older caldera approximately 6 km in diameter and open to the sea on the south side. No hot springs or fumaroles have been reported from Amukta. Sekora (1973, p. 29) reports the presence of a cinder cone near the northeastern shore of the island. Volcanic activity Well documented reports of historical Amukta volcanism are sparse; activity was noted from 1786 to 1791, and again in 1876 (Coats, 1950). Petroff (1884, citing Grewingk, 1850) lists activity at Amukhton in 1770, presumably the same vo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
