Mt. Everest is not a volcano.\n\nAs for an explanation, well, it is just not.  It doesn't spew lava, it has never spewed lava, and it is not ever expected to spew lava.

Usually there are warning signs that something is happening. Active volcanos such as Mt St Helens are continusly monitored for changes such as increase in earthquake activity, change in the shape of the volcano. Scientists can actually see changes to the shapre of hte volcano by GPS surveys. Like what is happening in the Pacific at teh moment (cant remember the name of the volcano just now) they know something is going to happen, but they cant place a time on it, so they have evacuated hte people. Most people are evacuated before hte volcano blows, but those that have ignored pleas do so at they're own risk. And yes as the dude above me pointed out, by means of a road.

Shield volcanoes are composed of basaltic, low viscosity lavas. which have low height/area aspect ratio (think about Hawaii).\nComposite volcanoes have a high height/are aspect ratio and are formed formed by andesitic to dacitic lavas, and pyroclasts. They are also called strato-volcanoes.\nThe domes, are dome shaped eruptions, lavas or volcanoes formed by dacitic to rhyolitic lavas, with some pyroclasts in the rims. They can also form cake like shapes or even very impressive protruding spine-shaped extrusion of very viscous magma.

Yellowstone volcanics are a localized feature that has shot through the overlying crust.  This is determined largely through geochemestry and heatflow studies.  The Hawiaan Islands are formed as a result of a hotspot.  You can see that the overlying plate has been moving with respect to the hotspot because the islands formed one at a tine in a line, showing plate direction.\n\nMt St. Helens is the result of a process called subduction.  The oceanic Pacific plate is being shoved underneath the North American plate.  As that plate is pushed deeper and deeper, heat and pressure create a partial melt that can rise to the surface and create volcanoes.  Look at the Aleutian chain, those are also subduction volcanoes, only there you see oceanic crust shoved under oceanic crust

Like most of the interior of the earth, the movements and dynamics of magma are poorly understood. However, it is known that an eruption usually follows movement of magma upwards into the solid layer (the earth's crust) beneath a volcano and occupying a magma chamber. Eventually, magma in the chamber is forced upwards and flows out across the planet surface as lava, or the rising magma can heat water in the surrounding landform and cause explosive discharges of steam; either this or escaping gases from the magma can produce forceful ejections of rocks, cinders, volcanic glass, and/or volcanic ash also known as tephra. While always displaying powerful forces, eruptions can vary from effusive to extremely explosive.\n\nMost volcanoes on the land are formed at destructive plate margins: where oceanic crust is forced below the continental crust because oceanic crust is denser than continental crust. As the oceanic crust 'subducts', it is forced into a higher-temperature region called the asthenosphere, and melts. Friction between these moving plates may also be a cause of melting. The reduced density of the melting rock forces the newly formed magma to rise. As the magma rises through weak areas in the continental crust it may eventually erupt as one or more volcanoes. For example, Mount St. Helens is found inland from the margin between the oceanic Juan de Fuca Plate and the continental North American Plate. The oceanic crust is normally a highly-'mafic' (iron and magnesium rich) rock, but as it rises through granitic (more silicic) continental plates, it may cause 'partial melting' of both mantle rocks and the plate rocks, producing magmas of varying silicity. Volcanic arcs forming near subduction zones, on the edges of continental plates, usually form high-silicity (high-viscosity) stratovolcanoes. Examples include the South American Andes and the Cascade range.\n \nA volcano generally presents itself to the imagination as a mountain sending forth from its summit great clouds of smoke with vast sheets of flame. The truth is that a volcano seldom emits either smoke or flame, although various combinations of hydrogen, carbon, oxygen, and sulfur do sometimes ignite. What is mistaken for smoke consists of vast volumes of fine dust (called volcanic ash), mingled with steam and other vapors, chiefly sulfurous. Most of what appears to be flames is the glare from the erupting materials, glowing because of their high temperature; this glare reflects off the clouds of dust and steam, resembling fire.\n\nPerhaps the most conspicuous part of a volcano is the crater, a basin of a roughly circular shape, formed by a vent (or vents) from which magma erupts as gases, lava, and ejecta. A crater can be of large dimensions, and sometimes of vast depth. Very large features of this sort are termed calderas. Some volcanoes consist of a crater alone, with scarcely any mountain at all; but in the majority of cases the crater is situated on top of a mountain (the volcano), which can tower to an enormous height. Volcanoes that terminate in a principal crater are usually of a conical form.\n\nVolcanic cones are usually smaller features composed of loose ash and cinder, with occasional masses of stone which have been tossed violently into the air by the eruptive forces (and are thus called ejecta). Within the crater of a volcano there may be numerous cones from which vapours are continually issuing, with occasional volleys of ashes and stones. In some volcanoes these cones form lower down the mountain, along rift zones or fractures. When the cone is eroded these rifts or lava filled fractures remain as radial near vertical dikes of volcanic rock. For example the radiating dikes at Shiprock in NW New Mexico.

It is unlikely that Devil's Tower in Wyoming ever erupted. It was formed as magma was forced upward into sedimentary rocks but there is no evidence that it ever breached the surface of the earth while it was still molten. The molten rock cooled and solidified while still under the surface, probably about 65 million years ago. Since then erosion of the softer sedimentary rocks around it have exposed it's spectacular rock. \n\nHere's the geologic history and further discussion at the National Park Service website:\nhttp://www.nps.gov/deto/geology.htm

Mt. St. Helens is a subduction volcano.\n\nVolcanism in subduction is caused by volitals, like H2O, CO2. These are carried down by the oceanic plate, mainly in the form of weak minerals. These minerals break down with pressure and temperature into stronger minerals that don't contain water and carbon dioxide. The leftover gases and liquids travel into the mantle (the mantle wedge) and hydrate the mantle, causing melting. The melt rises and then... volcano!

Earthquakes, epic centers, rumbles they all have the same meanings they come from two plat tectonics forcing one under the other. Either creating mountains are large crevice in the ground. In some cases earthquakes can trigger volcanic activate, but not always eruptions.

Well, yeah, there is a relationship.  Most of our recent volcanoes occur near the boundaries of plates.  At mid-ocean ridges hot magma is welling up and cooling to make the plates on either side larger.  Iceland, with its many volcanoes, is on the Mid-Atlantic Ridge.  Where oceanic plates are pushed under other plates (subducted), they are forced deeper into earth where it's hotter, and the subducted plate tends to melt.  The lighter parts of the melt try to work their way toward the surface (because they're less dense, and, hence buoyant), and cause volcanoes such as those of the Pacific's Ring of Fire--Indonesian volcanoes, Japanese volcanoes such as Mount Fuji, Alaska's volcanoes, the Cascade Range in Washington State, and so on.\n\nSome volcanoes are associated with "hot spots", where a plume of magma flows toward the surface, but is not associated with a plate boundary.  The Hawaiian Islands are an example of such a hot spot.  Plate tectonics also affect things here.  The plate moves over the hot spot, continually making new islands.  The newest one hasn't reached the surface yet.  Hawai'i is the newest one that's above the surface, and as you move north and west along the Hawai'ian Archipelago, the islands are progressively older and, because they've had more time to be eroded, smaller.  Northwest of the archipelago are the Emperor Seamounts, islands that were eroded until they no longer reach the ocean's surface.

Composite volcanoes/ strato volcanoe.\n\nSome of the Earth's grandest mountains are composite volcanoes--sometimes called stratovolcanoes. They are typically steep-sided, symmetrical cones of large dimension built of alternating layers of lava flows, volcanic ash, cinders, blocks, and bombs and may rise as much as 8,000 feet above their bases. Some of the most conspicuous and beautiful mountains in the world are composite volcanoes, including Mount Fuji in Japan, Mount Cotopaxi in Ecuador, Mount Shasta in California, Mount Hood in Oregon, and Mount St. Helens and Mount Rainier in Washington.\n\n\n**Here is a personal tip my teacher taught us..depending on the plate it's sitting on and the boundary you will know how the plates strike and collide ...in the case of helen think of yr two hands being forced together straight on max pressure eventually your fingers begin to cave and slide up ward together... it looks olmost pointy and cone shaped right? just like St. Helen... This is assuming you know about plates and faults ....Hopefully you do..if bot disregard..

Yes, it is the only active volcano on the European mainland. It's most recent eruptions were in the period from 1913 to 1944.

A destructive plate boundry causes one plate to be subducked below another, (sucked under basically) this causes it to melt and then rise to the surface where it forms the Mount Pelee volcano\n\nHope that helps

the gases build up that pushes the molten up, if there is snow causes hazardous and gaseous mud slide down the mountain.  Causes some tremors like earthquakes. Hazardous smoke (ash) cloud.  look up mount saint helens in Washington or the volcanoes in hawaii.  plus there are many throughout south america.  Pictures of mt. st. helens are awesome. I went there after it happened in 1980 it was phenomenal!  I felt the tremors up by bellingham. it was cool.

Mount Merapi did erupted and will be erupt in the next few weeks.\nMostly Merapi (means: Fire Mountain) misunderstood that it will explode and blasting volcanic materials to the atmosphere like a bomb.\nSo far only one "big bomb" explotion of Merapi recognise in the history time, during midlle ages that destroyed Hindus Kindom in Central Java. Even today we can find many of the Hindus and Budhis Temples around the area discovered burried in the ass / volcanic material from that explotion, from few inches up to several feet deep.\nNOwadays, Merapi eruption "only" resulting less then 1 mil plume. It happen because its craters are "open" and the magma/lava can easily flows out of the montain. The good things from Merapi beeing one of THe MOst Active Volcano in the world is that it is "very alife" and nothing really blocking the lava flow.\nThe most deadliest things from Merapi nowadays is the "Nue Ardante" or Piroclastic Flow, fllowing the eruption and Crater falls. Some volcalogist said that if you are accidently cought in the middle of this Piroclastic Flow, it is like you are hited by a hurrican and a hot furnice in the same time!\nIt is very hot! (300 - 600 degree Celcius) and its travel at the min. speed of 120 km per hours!\neven if you drive a car, you can not escape!\nIts only need 3 minutes (sometimes less) to travel from the crater in the top of the mountain to the leg/bottom!\nIts burn eveything! Even seeds 2 feet deep in the ground found death in the eruption in 1994.\nFor more information about Volcanos in Indonesia and how violent its explosion, you may find in some web pages below!\nNote: Indonesia Archipelago has the most Volcanoes in the worlds and also the deadliest

volcanoes are built when tectonic plates push together, the way mountains are formed. except volcanoes have magma inside of them. the gas and magma inside are under extreme pressure, and this pressure pushes its way through small cracks in the rock, eventually escaping in an eruption of gas that brings lava with it. a lot of people have been killed by eruptions, but i cant tell you how many. the lava takes weeks or months to cool down unless it hit the water, which will cool it in a matter of days.
