Tokachi Volcanic Group
is a volcanic group of mainly stratovolcanoes arrayed along a southwest–northeast axis in Hokkaidō, Japan. The volcanic group lies on the Kurile arc of the Pacific ring of fire, and consists of andesite, basalt, and dacite stratovolcanoes and lava domes. The group gets its name from the highest peak in the group, Mount Tokachi. The most recent activity is centered on the northwest end. List of volcanoes The following table lists the mountains in the volcanic group. Other peaks include: * Chuo-Kakokyu cone * Ko-Tokachi-Dake stratovolcano * Mae-Tokachi-Dake stratovolcano * Maru-Yama cone * Nokogiri-Dake stratovolcano * Suribachi-Kakokyu cone * Tairaga-Dake stratovolcano See also *List of volcanoes in Japan This is a list of active and extinct volcanoes in Japan.

Hokkaidō
is Japan's second largest island and comprises the largest and northernmost prefecture, making up its own region. The Tsugaru Strait separates Hokkaidō from Honshu; the two islands are connected by the undersea railway Seikan Tunnel. The largest city on Hokkaidō is its capital, Sapporo, which is also its only ordinance-designated city. Sakhalin lies about 43 kilometers (26 mi) to the north of Hokkaidō, and to the east and northeast are the Kuril Islands, which are administered by Russia, though the four most southerly are claimed by Japan. Hokkaidō was formerly known as ''Ezo'', ''Yezo'', ''Yeso'', or ''Yesso''. Nussbaum, Louis-Frédéric. (2005). "Hokkaidō" in Although there were Japanese settlers who ruled the southern tip of the island since the 16th century, Hokkaido was considered foreign territory that was inhabited by the indigenous people of the island, known as the Ainu people. While geographers such as Mogami Tokunai and Mamiya Rinzō explored the isla ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kurile Islands
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 kno ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Mount Biei
is a stratovolcano located in the Tokachi Volcanic Group, Hokkaidō, Japan. The mountain sits between the larger Mount Tokachi to the southwest and shorter Biei Fuji to the northeast. It forms part of the border between Shintoku and Biei towns. Geology The mountain consists of mostly non-alkaline mafic rock from the middle Pleistocene. History On July 16, 2009, a 64-year-old man died of exposure on Mount Biei, while five other members of his party had to be rescued. At the same time on nearby Mount Tomuraushi, eight members of an adventure tour group were also killed by exposure and a lone hiker was found dead one day later.

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] |
Dacite
Dacite () is a volcanic rock formed by rapid solidification of lava that is high in silica and low in alkali metal oxides. It has a fine-grained (aphanitic) to porphyritic texture and is intermediate in composition between andesite and rhyolite. It is composed predominantly of plagioclase feldspar and quartz. Dacite is relatively common, occurring in many tectonic settings. It is associated with andesite and rhyolite as part of the subalkaline volcanic rock, subalkaline tholeiite, tholeiitic and calc-alkaline magma series. Composition Dacite consists mostly of plagioclase feldspar and quartz with biotite, hornblende, and pyroxene (augite or enstatite). The quartz appears as rounded, corroded phenocrysts, or as an element of the ground-mass. The plagioclase in dacite ranges from oligoclase to andesine and labradorite. Sanidine occurs, although in small proportions, in some dacites, and when abundant gives rise to rocks that form rhyodacite, transitions to the rhyolites. The rel ...
