Kurile Arc
The Kuril Islands or Kurile Islands (; rus, Кури́льские острова́, r=Kuril'skiye ostrova, p=kʊˈrʲilʲskʲɪjə ɐstrɐˈva; Japanese: or ) are a volcanic archipelago currently administered as part of Sakhalin Oblast in the Russian Far East. It stretches approximately northeast from Hokkaido in Japan to Kamchatka Peninsula in Russia separating the Sea of Okhotsk from the north Pacific Ocean. There are 56 islands and many minor rocks. The Kuril Islands consist of the Greater Kuril Chain and the Lesser Kuril Chain. They cover an area of around , with a population of roughly 20,000. The islands have been under Russian administration since their 1945 invasion as the Soviet Union towards the end of World War II. Japan claims the four southernmost islands, including two of the three largest ( Iturup and Kunashir), as part of its territory, as well as Shikotan and the Habomai islets, which has led to the ongoing Kuril Islands dispute. The disputed islands are ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Volcanoes Of Hokkaido
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 sl ...

Mountains Of Hokkaido
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 300 metres (1,000 feet) above the surrounding land. A few mountains are isolated summits, but most occur in mountain ranges. Mountains are formed through 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 slumping and other forms of mass wasting, as well as through erosion by rivers and glaciers. High elevations on mountains produce colder climates than at sea level at similar latitude. These colder climates strongly affect the ecosystems of mountains: different elevations have different plants and animals. Because of the less hospitable terrain and ...

Mount Oakan
is a stratovolcano located in Akan National Park in Hokkaidō, Japan. Geography and geology Mount Oakan sits in the Akan caldera northeast of Lake Akan. The volcano rises some above the surrounding terrain. The top of the volcano is above sea level. The volcanic cone is some in diameter. There are three explosion craters at the summit. At at about , there is a fumarole. The volcano is made mostly from non-alkali mafic volcanic rock. The main rock type is andesite and dacite. History Mount Oakan emerged in the Late Pleistocene dropping pumice on Minamishikata. After that, continuous lava flows formed the bulk of the volcano. In the final stages of its life, a parasitic volcano formed a lava dome at the summit. According to its name and local legend, Mount Oakan is the male counterpart to Mount Meakan is an active stratovolcano located in Akan National Park in Hokkaidō, Japan.

Lake Akan
is a lake in Kushiro, Hokkaidō, Japan. It is located in Akan National Park and is a Ramsar Site. History Volcanic activity formed the lake some 6,000 years ago, when a lava dam was formed. The lake used to have a clarity of 8–9 meters in the 1930s. Pollution from local hotspring resorts has decreased the transparency to 3–4 meters. Flora and fauna The lake is famous for the marimo (''Aegagropila linnaei''), aggregations of algae that form into spherical shapes 2–30 cm in diameter. Other flora of the lake include the following: *Phragmites communis *Nuphar sp. *Potamogeton crispus * Hydrilla verticillata * Myriophyllum verticillatum *Vallisneria gigantea * Melosira italica * Asterionella formosa * Synedra Kokanee salmon (''Oncorhynchus nerka'') are native to Lake Akan. Other fauna of the lake include the following: *Zooplankton: ** Daphnia longiremis ** Bosmina coregoni ** Eurytemora affinis *Bottom: ** Chironomus plumosus **Tubificidae *Fish: **Cyprinus carpio ...

Akan National Park
is a national park located on the island of Hokkaidō, Japan. Along with Daisetsuzan National Park, these are the two oldest national parks in Hokkaidō. The park was established December 4, 1934. Akan is an area of volcanic craters and forests, covering . The park is famous for its crystal clear lakes, its hot springs, and its large marimo. It is the only place where marimo of appreciable size form naturally in Japan. Sites The park can be divided into two general areas, Kawayu and Akan. Kawayu Mount Iō and the Kawayu Onsen offer natural hotsprings and sulphur fumaroles. Around Lake Kussharo, a caldera lake, are Bihoro Pass, Mount Mokoto, and Mount Nishibetsu. At the lake, Wakoto Peninsula is an area with high ground temperatures and uniquely adapted wildlife. Lake Mashū is a caldera lake. It is one of the clearest lakes in the world with visibility up to 40 meters. Akan Akan Caldera is a large caldera over 20 km across. Emerging from within caldera is the ...

Holocene
The Holocene ( ) is the current geological epoch. It began approximately 11,650 cal years Before Present (), after the Last Glacial Period, which concluded with the Holocene glacial retreat. The Holocene and the preceding Pleistocene together form the Quaternary period. The Holocene has been identified with the current warm period, known as MIS 1. It is considered by some to be an interglacial period within the Pleistocene Epoch, called the Flandrian interglacial.Oxford University Press – Why Geography Matters: More Than Ever (book) – "Holocene Humanity" section https://books.google.com/books?id=7P0_sWIcBNsC The Holocene corresponds with the rapid proliferation, growth and impacts of the human species worldwide, including all of its written history, technological revolutions, development of major civilizations, and overall significant transition towards urban living in the present.

Late Pleistocene
The Late Pleistocene is an unofficial age in the international geologic timescale in chronostratigraphy, also known as Upper Pleistocene from a stratigraphic perspective. It is intended to be the fourth division of the Pleistocene Epoch within the ongoing Quaternary Period. It is currently defined as the time between c. 129,000 and c. 11,700 years ago. The Late Pleistocene equates to the proposed Tarantian Age of the geologic time scale, preceded by the officially ratified Chibanian (formerly known as Middle Pleistocene) and succeeded by the officially ratified Greenlandian. The estimated beginning of the Tarantian is the start of the Eemian interglacial period ( Marine Isotope Stage 5). It is held to end with the termination of the Younger Dryas, some 11,700 years ago when the Holocene Epoch began. The term Upper Pleistocene is currently in use as a provisional or "quasi-formal" designation by the International Union of Geological Sciences (IUGS). Although the three olde ...

Stratovolcano
A stratovolcano, also known as a composite volcano, is a conical volcano built up by many layers (strata) of hardened lava and tephra. Unlike shield volcanoes, stratovolcanoes are characterized by a steep profile with a summit crater and periodic intervals of explosive eruptions and effusive eruptions, although some have collapsed summit craters called calderas. The lava flowing from stratovolcanoes typically cools and hardens before spreading far, due to high viscosity. The magma forming this lava is often felsic, having high-to-intermediate levels of silica (as in rhyolite, dacite, or andesite), with lesser amounts of less-viscous mafic magma. Extensive felsic lava flows are uncommon, but have travelled as far as . Stratovolcanoes are sometimes called composite volcanoes because of their composite stratified structure, built up from sequential outpourings of erupted materials. They are among the most common types of volcanoes, in contrast to the less common shield volcano ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
