Northern Yatsugatake Volcanic Group
is a volcanic group of stratovolcanoes and lava domes located in Nagano Prefecture on Honshū in Japan. Description The Northern Yatsugatake Volcanic Group is part of the Yatsugatake Mountains. The northern group is defined as the mountains from Mount Futago to Natsuzawa Pass. The highest peak of the mountains is Mount Tengu and the elevation is 2,646 metres. The southern Yatsugatake mountains are steep and have alpine characteristics. The mountains of the Northern Yatsugatake Volcanic Group are gentler and lower. Yatsugatake is listed among the 100 famous mountains in Japan, but this refers to the Southern Yatsugatake Volcanic Group. Mount Tateshina is also mentioned as one of the 100 famous mountains, and it is part of the Northern Yatsugatake mountains, but is listed separately. These mountains are part of the Yatsugatake-Chūshin Kōgen Quasi-National Park. Geology and volcanic activity The volcanoes are stratovolcanos that are 1 million to 200,000 years old. The rock ...

Mount Yoko (Northern Yatsugatake)
also Mount Kita Yoko, is an active lava dome located in the Northern Yatsugatake Volcanic Group of the Yatsugatake Mountains, Honshū, Japan Japan ( ja, 日本, or , and formally , ''Nihonkoku'') is an island country in East Asia. It is situated in the northwest Pacific Ocean, and is bordered on the west by the Sea of Japan, while extending from the Sea of Okhotsk in the north .... Mount Yoko has shown the most recent activity and is now considered an active volcano. It last erupted about 800 years ago. The eruption consisted of ash with a lava flow of some 3 million cubic meters. The eruption was dated by corrected radiocarbon dating. The next previous eruption was in or after 400 BCE.

Cinder Cone
A cinder cone (or scoria cone) is a steep conical hill of loose pyroclastic fragments, such as volcanic clinkers, volcanic ash, or scoria that has been built around a volcanic vent. The pyroclastic fragments are formed by explosive eruptions or lava fountains from a single, typically cylindrical, vent. As the gas-charged lava is blown violently into the air, it breaks into small fragments that solidify and fall as either cinders, clinkers, or scoria around the vent to form a cone that often is symmetrical; with slopes between 30 and 40°; and a nearly circular ground plan. Most cinder cones have a bowl-shaped crater at the summit. Mechanics of eruption Cinder cones range in size from tens to hundreds of meters tall and often have a bowl-shaped crater at the summit. They are composed of loose pyroclastic material (cinder or scoria), which distinguishes them from ''spatter cones'', which are composed of agglomerated volcanic bombs. The pyroclastic material making up a cinder ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lake Matsubara
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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Andesite
Andesite () is a volcanic rock of intermediate composition. In a general sense, it is the intermediate type between silica-poor basalt and silica-rich rhyolite. It is fine-grained (aphanitic) to porphyritic in texture, and is composed predominantly of sodium-rich plagioclase plus pyroxene or hornblende. Andesite is the extrusive equivalent of plutonic diorite. Characteristic of subduction zones, andesite represents the dominant rock type in island arcs. The average composition of the continental crust is andesitic. Along with basalts, andesites are a component of the Martian crust. The name ''andesite'' is derived from the Andes mountain range, where this rock type is found in abundance. It was first applied by Christian Leopold von Buch in 1826. Description Andesite is an aphanitic (fine-grained) igneous rock that is intermediate in its content of silica and low in alkali metals. It has less than 20% quartz and 10% feldspathoid by volume, with at least 65% of the fe ... [...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 ...

Basalt
Basalt (; ) is an aphanite, aphanitic (fine-grained) extrusive igneous rock formed from the rapid cooling of low-viscosity lava rich in magnesium and iron (mafic lava) exposed at or very near the planetary surface, surface of a terrestrial planet, rocky planet or natural satellite, moon. More than 90% of all volcanic rock on Earth is basalt. Rapid-cooling, fine-grained basalt is chemically equivalent to slow-cooling, coarse-grained gabbro. The eruption of basalt lava is observed by geologists at about 20 volcanoes per year. Basalt is also an important rock type on other planetary bodies in the Solar System. For example, the bulk of the plains of volcanism on Venus, Venus, which cover ~80% of the surface, are basaltic; the lunar mare, lunar maria are plains of flood-basaltic lava flows; and basalt is a common rock on the surface of Mars. Molten basalt lava has a low viscosity due to its relatively low silica content (between 45% and 52%), resulting in rapidly moving lava flo ...

Yatsugatake-Chūshin Kōgen Quasi-National Park
is a quasi-national park on Honshū in Japan. It is rated a protected landscape (category V) according to the IUCN. The park includes the Yatsugatake Mountains and the surrounding lava plateaus: Tateshina plateau, Kirigamine, and Utsukushigahara. It straddles the border between Nagano and Yamanashi prefectures. Mount Aka is the highest point in the park at 2,899 m. The volcanoes of the Yatsugatake mountains erupted from the middle of the Fossa Magna ( ja) and spread skirts of lava south, east and west. Lake Matsubara, Shirakoma Pond, and Lake Shirakaba attract tourists to the region for boating, skating, and camping. Utsukushigahara is a lava plateau at the northern end of the park and offers views of the Northern Alps. The extensive lava plateau of Kirigahara is popular for hiking. There are also a number of onsens in addition to the hotsprings at Tateshina. The park was designated a quasi-national in 1964. Like all quasi-national parks in Japan, the park is managed by th ...

Mount Tateshina
also Suwa Fuji is a complex volcano located on the border of the municipalities of Chino and Tateshina in Nagano Prefecture, Japan. It has an elevation of . This mountain is one of the 100 Famous Japanese Mountains. Outline Mount Tateshina is a typical complex volcano. About the origin of the name of this mountain, ''tate'' means water-pepper, and ''shina'' means steps or high places. So ''Tateshina'' is literally a high mountain of water-peppers. The other name of this mountain ''Suwa Fuji'', literally, ''Mount Fuji of the Suwa region''. Mount Tateshina is an important part of Yatsugatake-Chūshin Kōgen Quasi-National Park. Route Routes to climb up Mount Tateshina are well-developed. The most popular route is to start from the Nanagome parking lot.
