Kunashir Island
Kunashir Island (; ; ), possibly meaning ''Black Island'' or ''Grass Island'' in Ainu, is the southernmost island of the Kuril Islands. The island has been under Russian administration since the end of World War II, when Soviet forces took possession of the Kurils. It is claimed by Japan (see Kuril Islands dispute). Geography Kunashir is separated by the Catherine Strait (Kunashiri Suido) from the island of Iturup, located 22 km northeast; Kunashir Strait (upper Nemuro Kaikyo) from Shiretoko Peninsula (Hokkaido Island), located 25 km to the west; Izmena Strait (Notsuke Suido or lower Nemuro Kaikyo) from Notsuke Peninsula (Hokkaido Island), located 16 km to the southwest; and by the South Kuril Strait (Yuzhno-Kurilski Proliv, Minami Chishima Kaikyo) from Shikotan and the Habomai Islands, 50 km to the east. Kunashir Island is visible from the nearby Japanese island of Hokkaido, from which it is separated by the Nemuro Strait. *Area: *Length: *Width ...

Sea Of Okhotsk
The Sea of Okhotsk; Historically also known as , or as ; ) is a marginal sea of the western Pacific Ocean. It is located between Russia's Kamchatka Peninsula on the east, the Kuril Islands on the southeast, Japan's island of Hokkaido on the south, the island of Sakhalin along the west, and a stretch of eastern Siberian coast along the west and north. Its northeast corner is the Shelikhov Gulf. The sea is named for the port of Okhotsk, itself named for the Okhota River. Geography The Sea of Okhotsk covers an area of , with a mean depth of and a maximum depth of . It is connected to the Sea of Japan on either side of Sakhalin: on the west through the Sakhalin Gulf and the Gulf of Tartary; on the south through the La Pérouse Strait. In winter, navigation on the Sea of Okhotsk is impeded by ice floes. Ice floes form due to the large amount of freshwater from the Amur River, lowering the salinity of upper levels, often raising the freezing point of the sea surface. The ...

Nemuro Strait
Nemuro Strait (), also called Notsuke Strait and Kunashirsky Strait (), is a strait separating Kunashir Island of the Kuril Islands, Russia ( claimed by Japan) from the Shiretoko Peninsula, Hokkaidō, Japan. The strait connects the Sea of Okhotsk in the north to the Izmeny Strait (пролив Измены) in the south. It is located on the southeastern borders of Sakhalin Oblast, Russia, and Nemuro Subprefecture is a Subprefectures of Hokkaido, subprefecture of Hokkaido, Hokkaido Prefecture, Japan. Japan claims the southern parts of the Kuril Islands dispute, disputed Kuril Islands (known as the Northern Territories in Japan) as part of this subprefectur ... of Japan. Along the strait runs the border between the two states. The Strait of Nemuro is approximately wide and long. The maximum depth is . The Japanese towns of Rausu and Shibetsu overlook the strait. The history of this land is interwoven with the abundant natural resource; salmon. As such it has come to be kno ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Volcanic
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."

Mendeleyeva
Mendeleyeva (; , ''Rausu-san'') is a stratovolcano located in the southern part of Kunashir Island, Kuril Islands, Russia. The dominantly andesitic- dacitic volcano is cut by two nested calderas, the larger 6–7 km in diameter and the smaller 3-3.5 km. A central cone that formed inside the younger caldera was breached to the west by a large debris avalanche about 4200 years ago. A lava dome that grew inside the avalanche scarp forms the 888 m high point of the volcano. Additional lava domes in the northern part of the older caldera are considered to represent flank activity of the younger caldera. The only unambiguous historical eruption was a small phreatic eruption in 1880. Four solfatara fields lie at the eastern and northern flanks of the central cone. Goriachy Pliazh geothermal field is located outside the caldera, along the eastern coast. See also *List of volcanoes in Russia This is a list of active and extinct volcanoes in Russia.

Hot Springs
A hot spring, hydrothermal spring, or geothermal spring is a Spring (hydrology), spring produced by the emergence of Geothermal activity, geothermally heated groundwater onto the surface of the Earth. The groundwater is heated either by shallow bodies of magma (molten rock) or by circulation through fault (geology), faults to hot rock deep in the Earth's crust. Hot spring water often contains large amounts of dissolved minerals. The chemistry of hot springs ranges from acid sulfate springs with a pH as low as 0.8, to alkaline chloride springs saturated with silica, to bicarbonate springs saturated with carbon dioxide and carbonate minerals. Some springs also contain abundant dissolved iron. The minerals brought to the surface in hot springs often feed communities of extremophiles, microorganisms adapted to extreme conditions, and it is possible that life on Earth had its origin in hot springs. Humans have made use of hot springs for bathing, relaxation, or medical therapy for th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Width
Length is a measure of distance. In the International System of Quantities, length is a quantity with dimension distance. In most systems of measurement a base unit for length is chosen, from which all other units are derived. In the International System of Units (SI) system, the base unit for length is the metre. Length is commonly understood to mean the most extended dimension of a fixed object. However, this is not always the case and may depend on the position the object is in. Various terms for the length of a fixed object are used, and these include height, which is vertical length or vertical extent, width, breadth, and depth. ''Height'' is used when there is a base from which vertical measurements can be taken. ''Width'' and ''breadth'' usually refer to a shorter dimension than ''length''. ''Depth'' is used for the measure of a third dimension. Length is the measure of one spatial dimension, whereas area is a measure of two dimensions (length squared) and volume ...

Area
Area is the measure of a region's size on a surface. The area of a plane region or ''plane area'' refers to the area of a shape or planar lamina, while '' surface area'' refers to the area of an open surface or the boundary of a three-dimensional object. Area can be understood as the amount of material with a given thickness that would be necessary to fashion a model of the shape, or the amount of paint necessary to cover the surface with a single coat. It is the two-dimensional analogue of the length of a curve (a one-dimensional concept) or the volume of a solid (a three-dimensional concept). Two different regions may have the same area (as in squaring the circle); by synecdoche, "area" sometimes is used to refer to the region, as in a " polygonal area". The area of a shape can be measured by comparing the shape to squares of a fixed size. In the International System of Units (SI), the standard unit of area is the square metre (written as m2), which is the area o ...

Habomai Islands
The Habomai Islands (; ) are a group of uninhabited islets (but for the Russian guards stationed there) in the southernmost Kuril Islands. The islands have been under Soviet/Russian administration since the Invasion of the Kuril Islands, 1945 invasion by the Soviet Union near the end of World War II. But together with Iturup (''Etorofu''), Kunashir (''Kunashiri''), and Shikotan, the islands are Kuril Islands dispute, claimed by Japan. History In the seventeenth century the Matsumae clan made efforts to administer the islands; by 1644 the islands had been mapped as Japanese territories. In 1732 the islands were mapped during the Great Northern Expedition, Russian Great Eastern Expedition. The Treaty of Shimoda, signed by Russia and Japan in 1855, recognised Japanese ownership of Iturup, Kunashir, Shikotan, and the Habomai Islands. The Habomai Islands were occupied by Soviet forces in the last few days of World War II. The islands were eventually annexed by the Soviet Union ...
