Hokkaidō Komagatake
, also , , or just is a andesitic stratovolcano on the border between Mori, Shikabe, and Nanae, all within the Oshima Subprefecture of Hokkaidō, Japan. Occurrence of volcanic activity started some 30,000 years ago. Following roughly 5,000 years of dormancy, volcanic activity at Mount Koma-ga-take restarted at the start of the 17th century, triggering the Kan'ei Great Famine The Kan'ei Great Famine ( ') was a famine which affected Japan during the reign of Empress Meishō in the Edo period. The estimated number of deaths due to starvation is between 50,000 and 100,000. The famine is generally considered to have begun in ... in 1640.

Pleistocene Stratovolcanoes
The Pleistocene ( , often referred to as the ''Ice age'') is the geological epoch that lasted from about 2,580,000 to 11,700 years ago, spanning the Earth's most recent period of repeated glaciations. Before a change was finally confirmed in 2009 by the International Union of Geological Sciences, the cutoff of the Pleistocene and the preceding Pliocene was regarded as being 1.806 million years Before Present (BP). Publications from earlier years may use either definition of the period. The end of the Pleistocene corresponds with the end of the last glacial period and also with the end of the Paleolithic age used in archaeology. The name is a combination of Ancient Greek grc, label=none, πλεῖστος, pleīstos, most and grc, label=none, καινός, kainós (latinized as ), 'new'. At the end of the preceding Pliocene, the previously isolated North and South American continents were joined by the Isthmus of Panama, causing a faunal interchange between the two reg ...

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 ...

Kan'ei Great Famine
The Kan'ei Great Famine ( ') was a famine which affected Japan during the reign of Empress Meishō in the Edo period. The estimated number of deaths due to starvation is between 50,000 and 100,000. The famine is generally considered to have begun in 1640 and lasted into 1643. It was named after the Kan'ei era (1624–1644). The ruling ''shōgun'' during the famine was Tokugawa Iemitsu. Events leading to the famine Due to large numbers of internally displaced persons in the aftermath of the Shimabara Rebellion, and the rinderpest epizooty, which broke out in Kyushu in 1638 and was impossible to contain, led to mass deaths of cattle in Western Japan, which reduced agricultural productivity in 1640 due to the scarcity of working animals. Also, motivation among farmers was weakening due to the extreme impoverishment of low-ranking samurai class members. The increased spending after the 1635 reformation of Sankin-kōtai (increasing frequency of ''daimyō'' annual trips to Edo) did not ...

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] |
