Actually Canada IS on the Ring of Fire, which circles the Pacific Ocean more or less.\n\nCanada does have volcanoes on its west cost where the Rockies and Cascades continue north out of the United States.  \n\nYou don't have to be on the Ring of Fire to have volcanoes either, just along an active fault typically.  There are volcanoes all over the world where the plates meet.  Canada doesn't have volcanoes over most of its land though because it is spread across a continental plate which is too thick in the middle to have hot spots (like the Pacific plate does where we see the Hawaiian islands).  Where it meets the Pacific and Juan de Fuca plate in the west though there is enough movement to form mountains and strato volcanoes (like Mt. St. Helens which is not far from Canada, in Washington State).

type quebec + geology + St. Elle d'orford in your browser.  Also, local universities can help.  I have stratigraphic charts, but none for Canada, just US (although they are called COSUNA, for Correlation of Stratigraphic Units of North America).  Keep looking..the rocks won't go away!  And, good luck.

A volcano is a geological landform usually generated by the eruption through a planet's surface of magma, molten rock welling up from the planet's interior. Other forms of volcano include ice volcanoes (particularly on some moons of Jupiter, Saturn and Neptune) and mud volcanoes. On Earth, volcanoes tend to occur near the boundaries of crustal plates. Important exceptions exist in hotspot volcanoes, which occur at locations far from plate boundaries; hotspot volcanoes are also found elsewhere in the solar system, especially on its rocky planets and moons.\n \nSmoking Bromo and Semeru (background) volcanoes on Java in Indonesia.\n\nMud volcanoes are formations often not associated with known magmatic activity. Active mud volcanoes tend to involve temperatures much lower than those of igneous volcanoes, except when a mud volcano is actually a vent of an igneous volcano.\n\nThe name "volcano" is thought to derive from Vulcano, a volcanic island in the Aeolian Islands of Italy whose name in turn originates from Vulcan, the name of a god of fire in Roman mythology. The study of volcanoes is called volcanology (sometimes spelled vulcanology).\nContents [hide]\n1 Volcano classification \n1.1 Erupted material\n1.2 Shape \n1.2.1 Shield volcanoes\n1.2.2 Cinder cones\n1.2.3 Stratovolcanoes\n1.2.4 Supervolcanoes\n1.2.5 Submarine volcanoes\n1.3 Subglacial volcanoes\n1.4 Classifying volcanic activity\n2 Notable volcanoes \n2.1 Volcanoes on Earth\n2.2 Volcanoes elsewhere in the solar system\n3 Volcanology \n3.1 Volcano formation \n3.1.1 Tectonic environments of volcanoes \n3.1.1.1 Constructive plate margins\n3.1.1.2 Destructive plate margins\n3.1.1.3 Hotspots\n4 Predicting volcanic eruptions \n4.1 Seismicity\n4.2 Gas emissions\n4.3 Ground deformation\n4.4 Iceberg tremors\n4.5 Hydrology\n4.6 Remote Sensing \n4.6.1 Local Predictions\n4.6.2 Early Warning for Lahars\n4.7 Predicting future eruptions of Mt.

If the erupted magma contains a high percentage (>65%) of silica, the lava is called felsic. Felsic lavas tend to be highly viscous (not very fluid) and are erupted as domes or short, stubby flows. Viscous lavas tend to form stratovolcanoes or lava domes. Lassen Peak in California is an example of a volcano formed from felsic lava and is actually a large lava dome. This type of volcano has a tendency to explode when erupting, because the viscous lava traps volatiles (gases), which cannot escape easily. Mount Pelée on the island of Martinique is another example. Pyroclastic flows (ignimbrite) are highly hazardous products of such volcanoes, since they are composed of molten volcanic ash too heavy to go up into the atmosphere, so they hug the volcano's slopes and travel far from their vents during large eruptions. Temperatures as high as 1,200 °C are known to occur in pyroclastic flows, which will incinerate everything flammable in their path and thick layers of hot pyroclastic flow deposits can be laid down, often up to many meters thick. Alaska's Valley of Ten Thousand Smokes, formed by the eruption of Novarupta near Katmai in 1912, is an example of a thick pyroclastic flow or ignimbrite deposit.\n\nIf, on the other hand, the magma contains a relatively low percentage of silica, the lava is called mafic or basaltic and will be fluid as it erupts, capable of flowing for long distances. Mafic refers to the chemical composition of the lava—it contains higher percentages of magnesium (Mg) and iron (Fe), and correspondingly lower percentages of silica. Due to its low viscosity, v

Because of the volcanoes.

Geologists generally group volcanoes into four main kinds--cinder cones, composite volcanoes, shield volcanoes, and lava domes. \n\nIn regard to your question, Cinder cones are the simplest type of volcano. They are built from particles and blobs of congealed lava ejected from a single vent. As the gas-charged lava is blown violently into the air, it breaks into small fragments that solidify and fall as cinders around the vent to form a circular or oval cone. Most cinder cones have a bowl-shaped crater at the summit and rarely rise more than a thousand feet or so above their surroundings. Cinder cones are numerous in western North America as well as throughout other volcanic terrains of the world.\n\nShield volcanoes are built almost entirely of fluid lava flows. Flow after flow pours out in all directions from a central summit vent, or group of vents, building a broad, gently sloping cone of flat, domical shape, with a profile much like that of a warrior's shield. They are built up slowly by the accretion of thousands of highly fluid lava flows called basalt lava that spread widely over great distances, and then cool as thin, gently dipping sheets. Lavas also commonly erupt from vents along fractures (rift zones) that develop on the flanks of the cone. Some of the largest volcanoes in the world are shield volcanoes. In northern California and Oregon, many shield volcanoes have diameters of 3 or 4 miles and heights of 1,500 to 2,000 feet. The Hawaiian Islands are composed of linear chains of these volcanoes including Kilauea and Mauna Loa on the island of Hawaii-- two of the world's most active volcanoes. The floor of the ocean is more than 15,000 feet deep at the bases of the islands. As Mauna Loa, the largest of the shield volcanoes (and also the world's largest active volcano), projects 13,677 feet above sea level, its top is over 28,000 feet above the deep ocean floor.

You think we are seeing lots of volcanic activity NOW?\n\nRent a copy of Walt Disney's "Fantasia" and watch the part about the early ages of the Earth.\n\nFor millions of years, all this planet DID was erupt.\n\nOf course, your question is tied more to relatively recent times.  The planet seems to pass through periods of greater and lesser volcanic activity.  Much of it is stimulated by movement of the great "tectonic plates" on which our globe is formed.  These are huge chunks of the Earth's crust that slide and bump into one another.  They "float" on top of the more liquid, or molten, components of the Earth's core.\n\nVulcanologists, or specialists in volcanoes, can answer your question with greater precision.  In general, there has been an apparent increase in volcanic activity over the past 40-50 years.  That's how long I've been paying attention, anyhow.  But some of this appearance of activity is a product of remembering volcanic events - a few this year, another one or two some years later, and so on.  Most what I have noticed is that volcanic activity seems to have moved around the world.  Where one volcano goes ka-boom, or squirts out some lava for a time and then goes quiet, later there's a new one doing the same elsewhere.  After a time, it seems there are lava flows everywhere, when in fact there are not.\n\nThe most persistent volcanic activity I can remember is in Hawaii, where for at least 20 years (or so it seems) the Big Island has slowly been growing as a result of constant lava flow.\n\nThe 1800's overall seem to have been far more active in terms of volcanic eruptions and disasters than the past 100 years.  Some of the most horrendous volcanic disasters took place in that century.\n\nWe should remember that ours is not a "quiet" planet, but an ever-active ball of dirt, water and air.  It's an interesting place, eh?

Canada- low crime rate- never been to war and it doesn't look that they ever will be going to.

Why not consider Canada?  No Bush there.

Hmmmmm ..... some volcano probably??   You probably know that - can't think of one that fits.

Because Canada is known as a friendly country and they don't have tons of enemies like the Americans do.  Most other countries hate America.

...And the ring of fire is located around the Pacific.  \n\nVolcanoes can also be found in Iceland, where it lies above a hot spot and a Mid Ocean Ridge.  They also tend to coincide with mantle plumes surging from the core mantle boundary as well as plate convergent (subduction) and divergent (rifts and MOR) settings, but further details can be found in various websites --> search on google.\n\nWikipedia or the United States Geologic Survey (usgs.gov?) websites may have some useful info about volcanoes.

The most common place to find shield volcanoes is over hotspots (such as Hawai'i, the Galapagos, etc.). This is because hotspot magmas are almost always hot basalts and therefore the erupted lavas have low viscosities. Low viscosity lavas cannot be piled up very steeply so they form shield volcanoes.\nSubduction-zone magmas are almost always cooler and they are higher in silica, both qualities that make the lavas more viscous. These magmas are able to pile up into steep domes and additionally make the volcanoes more explosive so that they have a greater percentage of ash. This makes the volcanoes steep strato-cones instead of shields. It isn't impossible to find shield volcanoes along lines of arc volcanoes (for example Masaya in Nicaragua), but it is rare.

A subglacial volcano is a volcanic form produced by eruptions beneath a glacier or beneath the surface of a lake within a glacier. Today they are most common in Iceland and Antarctica; older formations of this type are found also in parts of Canada. Their shape tends to be characteristic and unusual, with flat top and steep sides. If the heat produced by the volcano is high enough to melt through the ice layer, however, the volcano assumes a more conventional shape.

Volcanoes occur in hotspots where the earths crust is thin, most often around subduction zones, or areas where the tectonic plates are colliding and one plate is sliding under the other. There are other places where volcanos or hotspots occur, such as Hawaii, but in that case the chain of islands known as Hawaii are being pushed north by the movement of the tectonic plate there. In fact right now there is another island being built beneath the ocean just south of the main island. The earth is slowly cooling though events such as these. Beneath the crust the magma is under intense pressure and it has to escape somewhere, so it does escape at these weak places in the earths crust which we call volcanos.\n\nOf course I could have just plagarized my answer like  mikah_nine, but instead I opted to answer from my own knowledge and even include a source.

a natural disaster such as earthquakes are possible anywhere.  just some areas (along fault lines) are more prone to the effects.  For my money, i would be most worried about a large volcano that spews ash into the atmosphere and causes the earth's climate to dramatically change.  Not much you can do about that!

Until recently, the term "supervolcano" was never used in volcanology. It was coined on TV to refer to those volcanoes that produce massive eruptions able to have a climate impact.
