Mount Azumaya
is a stratovolcano in Japan. The peak lies on the border of Nagano Prefecture and Gunma Prefecture. There exist alternative spellings of the mountain's name, like: 吾妻山 and 吾嬬山 which is read as "Agatsuma-yama" (Mount Agatsuma). In the village Tsumagoi, the mountain is spelled 吾妻山. The mountain should not be confused with of which there are two, one in Nagano Prefecture and the other in Saitama Prefecture. Though the reading is the same, the name written in Kanji differs from the mountain in this article. Outline Mount Azumaya was formed between 900,000 and 300,000 years ago by andesite lava flowing out of a stratovolcano. An eruption 340,000 years ago formed a caldera of circa 3 kilometers in diameter. Through erosion the mountain has arrived at its present form with several peaks. is the general term for the following peaks lying roughly on a circle: , Mount Azumaya, , . The famous Sugadaira Kōgen ski area is found on the mountain's southwest (Nagano- ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Stratovolcano
A stratovolcano, also known as a composite volcano, is a typically conical volcano built up by many alternating layers (strata) of hardened lava and tephra. Unlike shield volcanoes, stratovolcanoes are characterized by a steep profile with a summit crater and explosive eruptions. Some have collapsed summit craters called calderas. The lava flowing from stratovolcanoes typically cools and solidifies 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 can travel as far as 8 km (5 mi). The term ''composite volcano'' is used because strata are usually mixed and uneven instead of neat layers. They are among the most common types of volcanoes; more than 700 stratovolcanoes have erupted lava during the Holocene Epoch (the last 11,700 years), and many ol ...

Volcanoes Of Nagano Prefecture
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."

Mountains Of Gunma Prefecture
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 above the surrounding land. A few mountains are inselberg, isolated summits, but most occur in mountain ranges. mountain formation, Mountains are formed through tectonic plate, 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 Slump (geology), slumping and other forms of mass wasting, as well as through erosion by rivers and glaciers. High elevations on mountains produce Alpine climate, colder climates than at sea level at similar latitude. These colder climates strongly affect the Montane ecosystems, ecosystems of mountains: different elevations hav ...

List Of Mountains In Japan
A list is a set of discrete items of information collected and set forth in some format for utility, entertainment, or other purposes. A list may be memorialized in any number of ways, including existing only in the mind of the list-maker, but lists are frequently written down on paper, or maintained electronically. Lists are "most frequently a tool", and "one does not ''read'' but only ''uses'' a list: one looks up the relevant information in it, but usually does not need to deal with it as a whole".Lucie Doležalová,The Potential and Limitations of Studying Lists, in Lucie Doležalová, ed., ''The Charm of a List: From the Sumerians to Computerised Data Processing'' (2009). Purpose It has been observed that, with a few exceptions, "the scholarship on lists remains fragmented". David Wallechinsky, a co-author of '' The Book of Lists'', described the attraction of lists as being "because we live in an era of overstimulation, especially in terms of information, and lists help us ...

Mount Neko
is a mountain in Jōshin'etsu-kōgen National Park with an elevation of , located near Ueda and Suzaka in Nagano Prefecture, Japan. It is one of the because of the flowers of Parnassia palustris which bloom in September. Along with Mount Azumaya, Mount Neko is one of the published by The Shinano Mainichi Shimbun. The mountain should not be confused with a similarly named Mount Neko (根子岳) in Kumamoto Prefecture. Mount Neko forms the western peak along the rim of the caldera. This volcano was active 900,000–300,000 years ago. Other peaks on the caldera are Mount Azumaya () to the south, () to the east, and () to the north. Mount Azumaya is one of the 100 Famous Japanese Mountains. Mountain Climbing ; Ascent * One of the most frequently used trails begins at Sugadaira Farm ().

Ski Area
A ski area is the terrain and supporting infrastructure where skiing and other snow sports take place. Such sports include alpine and cross-country skiing, snow boarding, tubing, sledding, etc. Ski areas may stand alone or be part of a ski resort. Scope of activities The US Forest Service defines a ski area as: "a site and associated facilities that has been primarily developed for alpine or Nordic skiing and other snow sports, but may also include, in appropriate circumstances, facilities necessary for other seasonal or year-round natural resource-based recreation activities, provided that a preponderance of revenue generated by the ski area derives from the sale of alpine and Nordic ski area passes and lift tickets, revenue from alpine, Nordic, and other snow sport instruction, and gross revenue from ancillary facilities that support alpine or Nordic skiing and other snow sports." Notable examples Ski areas can extend over several municipalities (ex: La Plagne in France, ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |
