Lake Kussharo
is a caldera lake in Akan National Park, eastern Hokkaidō, Japan. As with many geographic names in Hokkaidō, the name derives from the Ainu language. It is the largest caldera lake in Japan in terms of surface area, and sixth largest lake in Japan. It is also the largest lake in Japan to freeze over completely in winter. The name Lake Kutcharo is also sometimes used. The lake's central island, Nakajima (not to be confused with another island of the same name in Lake Tōya), is a stratovolcano. It is also Japan's largest recursive island. Volcanic gases render the lake water acidic, and it supports few fish except in areas where inflowing streams dilute the water. Rainbow trout, which are also resistant to fairly acidic water, have been artificially introduced. In 1951, a rare form of cicada ('' Hyalessa maculaticollis'') was discovered, and is now protected by the government. The lake is also on the migratory path of the whooper swan. Along the lake shore are several outdoo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Acidic
In computer science, ACID ( atomicity, consistency, isolation, durability) is a set of properties of database transactions intended to guarantee data validity despite errors, power failures, and other mishaps. In the context of databases, a sequence of database operations that satisfies the ACID properties (which can be perceived as a single logical operation on the data) is called a ''transaction''. For example, a transfer of funds from one bank account to another, even involving multiple changes such as debiting one account and crediting another, is a single transaction. In 1983, Andreas Reuter and Theo Härder coined the acronym ''ACID'', building on earlier work by Jim Gray who named atomicity, consistency, and durability, but not isolation, when characterizing the transaction concept. These four properties are the major guarantees of the transaction paradigm, which has influenced many aspects of development in database systems. According to Gray and Reuter, the IBM Informa ...

Lakes Of Hokkaido
A lake is an area filled with water, localized in a basin, surrounded by land, and distinct from any river or other outlet that serves to feed or drain the lake. Lakes lie on land and are not part of the ocean, although, like the much larger oceans, they do form part of the Earth's water cycle. Lakes are distinct from lagoons, which are generally coastal parts of the ocean. Lakes are typically larger and deeper than ponds, which also lie on land, though there are no official or scientific definitions. Lakes can be contrasted with rivers or streams, which usually flow in a channel on land. Most lakes are fed and drained by rivers and streams. Natural lakes are generally found in mountainous areas, rift zones, and areas with ongoing glaciation. Other lakes are found in endorheic basins or along the courses of mature rivers, where a river channel has widened into a basin. Some parts of the world have many lakes formed by the chaotic drainage patterns left over from the last ice ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Volcanic Crater Lakes
A volcano is a rupture 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 most 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 can also form where there is stretching and thinning of the crust's plates, such as in the East African Rift and the Wells Gray-Clearwater volcanic field and Rio Grande rift in North America. Volcanism away from plate boundaries has been postulated to arise from upwelling diapirs from the core–mantle boundary, deep in the Earth. This results in hotspot volcanism, of which the Hawaiian hotspot is an example. Volcanoes are usually not created where two tectonic plates slide pa ...

Calderas Of Hokkaido
A caldera ( ) is a large cauldron-like hollow that forms shortly after the emptying of a magma chamber in a volcano eruption. When large volumes of magma are erupted over a short time, structural support for the rock above the magma chamber is gone. The ground surface then collapses into the emptied or partially emptied magma chamber, leaving a large depression at the surface (from one to dozens of kilometers in diameter). Although sometimes described as a crater, the feature is actually a type of sinkhole, as it is formed through subsidence and collapse rather than an explosion or impact. Compared to the thousands of volcanic eruptions that occur each century, the formation of a caldera is a rare event, occurring only a few times per century. Only seven caldera-forming collapses are known to have occurred between 1911 and 2016. More recently, a caldera collapse occurred at Kīlauea, Hawaii in 2018. Etymology The term ''caldera'' comes from Spanish ', and Latin ', meaning "c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tourism In Japan
Japan attracted 31.88 million international tourists in 2019. Japan has 21 World Heritage Sites, including Himeji Castle, Historic Monuments of Ancient Kyoto and Nara. Popular foreigner attractions include Tokyo and Hiroshima, Mount Fuji, ski resorts such as Niseko in Hokkaido, Okinawa, riding the shinkansen and taking advantage of Japan's hotel and hotspring network. The ''2017'' ''Travel and Tourism Competitiveness Report'' ranked Japan 4th out of 141 countries overall, which was the highest in Asia. Japan gained relatively high scores in almost all of the featured aspects, such as health and hygiene, safety and security, cultural resources and business travel. History The origins of early traditions of visits to picturesque sites are unclear, but an early sight-seeing excursion was Matsuo Bashō's 1689 trip to the then "far north" of Japan, which occurred not long after Hayashi Razan categorized the Three Views of Japan in 1643. During the Edo era of Japan, from ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lava Dome
In volcanology, a lava dome is a circular mound-shaped protrusion resulting from the slow extrusion of viscous lava from a volcano. Dome-building eruptions are common, particularly in convergent plate boundary settings. Around 6% of eruptions on Earth are lava dome forming. The geochemistry of lava domes can vary from basalt (e.g. Semeru, 1946) to rhyolite (e.g. Chaiten, 2010) although the majority are of intermediate composition (such as Santiaguito, dacite-andesite, present day) The characteristic dome shape is attributed to high viscosity that prevents the lava from flowing very far. This high viscosity can be obtained in two ways: by high levels of silica in the magma, or by degassing of fluid magma. Since viscous basaltic and andesitic domes weather fast and easily break apart by further input of fluid lava, most of the preserved domes have high silica content and consist of rhyolite or dacite. Existence of lava domes has been suggested for some domed structures on the Mo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Lake Monster
A lake monster is a lake-dwelling entity in folklore. The most famous example is the Loch Ness Monster. Depictions of lake monsters are often similar to those of sea monsters. In the ''Motif-Index of Folk-Literature'', entities classified as "lake monsters", such as the Scottish Loch Ness Monster, the American Chessie, and the Swedish Storsjöodjuret fall under B11.3.1.1. ("dragon lives in lake"). Theories According to the Swedish naturalist and author Bengt Sjögren (1980), present-day lake monsters are variations of older legends of water kelpies. Sjögren claims that the accounts of lake-monsters have changed during history, as do others. Older reports often talk about horse-like appearances, but more modern reports often have more reptile and dinosaur-like appearances; he concludes that the legendary kelpies have evolved into the present day saurian lake-monsters since the discovery of dinosaurs and giant aquatic reptiles and the popularization of them in both scientific and ...

Loch Ness
Loch Ness (; gd, Loch Nis ) is a large freshwater loch in the Scottish Highlands extending for approximately southwest of Inverness. It takes its name from the River Ness, which flows from the northern end. Loch Ness is best known for claimed sightings of the cryptozoological Loch Ness Monster, also known affectionately as "Nessie" ( gd, Niseag). It is one of a series of interconnected, murky bodies of water in Scotland; its water visibility is exceptionally low due to a high peat content in the surrounding soil. The southern end connects to Loch Oich by the River Oich and a section of the Caledonian Canal. The northern end connects to Loch Dochfour via the River Ness, which then ultimately leads to the North Sea via the Moray Firth. Loch Ness is the second-largest Scottish loch by surface area after Loch Lomond at , but due to its great depth it is the largest by volume in the British Isles. Its deepest point is , making it the second deepest loch in Scotland after Loch ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Whooper Swan
The whooper swan ( /ˈhuːpə(ɹ) swɒn/) (''Cygnus cygnus''), also known as the common swan, pronounced ''hooper swan'', is a large northern hemisphere swan. It is the Eurasian counterpart of the North American trumpeter swan, and the type species for the genus '' Cygnus''. Taxonomy Francis Willughby and John Ray's ''Ornithology'' of 1676 referred to this swan as "the Elk, Hooper, or wild Swan". It was one of the many bird species originally described by Carl Linnaeus in the 1758 10th edition of his ''Systema Naturae'', where it was given the binomial name of ''Anas cygnus''. The species name is from ''cygnus'', the Latin for "swan". Description The whooper swan is similar in appearance to Bewick's swan. It is larger, however, at a length of and a wingspan of . The weight is typically in the range of , with an average of for males and for females. The verified record mass was for a wintering male from Denmark. It is considered to be amongst the heaviest flying birds. Amon ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
