Mount Yōtei
is an active stratovolcano located in Shikotsu-Toya National Park, Hokkaidō, Japan. It is also called , "Ezo" being an old name for the island of Hokkaido, because it resembles Mount Fuji. The mountain is also known as and . It is one of the 100 famous mountains in Japan. Geology Mount Yōtei is mostly composed of andesite and dacite. The stratovolcano is symmetrical, adding to its resemblance to Mount Fuji. Eruptive history Tephrochronology indicates two eruptions at Mount Yotei. The most recent circa 1050 BC from a cone emerging from the northwest flank of the mountain at . The earlier eruption is dated from circa 3550 BC. Climate Etymology Mount Yōtei is also known as Ezo Fuji because of its almost perfectly conical shape resembling Mount Fuji, making it one of the “local Fujis” found in different regions of Japan. Through Japan's Meiji, Taishō and Shōwa eras it was known by multiple names: “Shiribeshi-yama/Kōhō-Yōtei-zan", "Makkarinupuri" and "Ezo ...

Meiji (era)
The is an era of Japanese history that extended from October 23, 1868 to July 30, 1912. The Meiji era was the first half of the Empire of Japan, when the Japanese people moved from being an isolated feudal society at risk of colonization by Western powers to the new paradigm of a modern, industrialized nation state and emergent great power, influenced by Western scientific, technological, philosophical, political, legal, and aesthetic ideas. As a result of such wholesale adoption of radically different ideas, the changes to Japan were profound, and affected its social structure, internal politics, economy, military, and foreign relations. The period corresponded to the reign of Emperor Meiji. It was preceded by the Keiō era and was succeeded by the Taishō era, upon the accession of Emperor Taishō. The rapid modernization during the Meiji era was not without its opponents, as the rapid changes to society caused many disaffected traditionalists from the former samurai ...

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 ...

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 slide pa ...

Stratovolcanoes Of Japan
A stratovolcano, also known as a composite volcano, is a Volcanic cone, 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 Igneous rock#Mineralogical classification, 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 v ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Active Volcanoes
An active volcano is a volcano which is either erupting or is likely to erupt in the future. An active volcano which is not currently erupting is known as a dormant volcano. Overview Tlocene Epoch. Most volcanoes are situated on the Pacific Ring of Fire. An estimated 500 million people live near active volcanoes. ''Historical time'' (or recorded history) is another timeframe for ''active''. However, the span of recorded history differs from region to region. In China and the Mediterranean, it reaches back nearly 3,000 years, but in the Pacific Northwest of the United States and Canada, it reaches back less than 300 years, and in Hawaii and New Zealand it is only around 200 years. The incomplete ''Catalogue of the Active Volcanoes of the World'', published in parts between 1951 and 1975 by the International Association of Volcanology, uses this definition, by which there are more than 500 active volcanoes. , the Smithsonian Global Volcanism Program recognizes 560 volcanoes with ...

Ainu People
The Ainu are the indigenous people of the lands surrounding the Sea of Okhotsk, including Hokkaido Island, Northeast Honshu Island, Sakhalin Island, the Kuril Islands, the Kamchatka Peninsula and Khabarovsk Krai, before the arrival of the Yamato Japanese and Russians. These regions are referred to as in historical Japanese texts. Official estimates place the total Ainu population of Japan at 25,000. Unofficial estimates place the total population at 200,000 or higher, as the near-total assimilation of the Ainu into Japanese society has resulted in many individuals of Ainu descent having no knowledge of their ancestry. As of 2000, the number of "pure" Ainu was estimated at about 300 people. In 1966, there were about 300 native Ainu speakers; in 2008, however, there were about 100. Names This people's most widely known ethnonym, "Ainu" ( ain, ; ja, アイヌ; russian: Айны) means "human" in the Ainu language, particularly as opposed to , divine beings. Ainu also i ...

Abe No Hirafu
was a Japanese military strategist and commander of the Asuka period. Some sources say he lived from c.575-664 Biography Events in his life are accounted in the Nihon Shoki and Kojiki, both written several decades after his death. His father's name and origin are unknown, as the written sources contradict one another, and may have been altered to glorify the genealogy of then-living clans. After reaching adulthood, Abe was a governor of Koshi Province. In 658, he defeated the Mishihase in "Watarishima" (which may mean Tsugaru Peninsula or Hokkaido) at the request of the native inhabitants. His men continued to raid and plunder in Hokkaido and Okushiri Island until 660, bringing numerous trophies and prisoners to court. His trophies included at least 2 live bears, 70 bear hides, and 353 prisoners. In March 660, local allies asked for his military assistance at Ishikari River in Hokkaido, where he was victorious again. In 662 his lord (soon to become the Emperor Tenji) assigned ...
