It is confirmed active. \n\nIt may erupt anytime. no worries though, the Japanese people are currently working on a dam to control and direct the flow of lava.\n\nBut make sure it doesn't erupt because I have not climbed it yet, along with other people around the world!

Dormant volcanoes are those that are not currently active (as defined above), but could become restless or erupt again. Confusion however, can arise because many volcanoes which scientists consider to be active are referred to as dormant by laypersons or in the media.\n\nExtinct volcanoes are those that scientists consider unlikely to erupt again. Whether a volcano is truly extinct is often difficult to determine. Since "supervolcano" calderas can have eruptive lifespans sometimes measured in millions of years, a caldera that has not produced an eruption in tens of thousands of years is likely to be considered dormant instead of extinct.\n\nFor example, the Yellowstone Caldera in Yellowstone National Park is at least 2 million years old and hasn't erupted violently for approximately 640,000 years, although there has been some minor activity relatively recently, with hydrothermal eruptions less than 10,000 years ago and lava flows about 70,000 years ago. For this reason, scientists do not consider the Yellowstone Caldera extinct. In fact, because the caldera has frequent earthquakes, a very active geothermal system (i.e., the entirety of the geothermal activity found in Yellowstone National Park), and rapid rates of ground uplift, many scientists consider it to be an active volcano.

Simple answer: distance and monitoring.\n\nPlacing sensitive probes on the volcano to monitor any movements, shifts, temperature change, growth, seismic activity, etc., will give some indications of what a volcano is up to. If vulcanologist's studying the volcano's activities consider an eruption is about to happen, then an early warning can be issued for an evacuation.\n\nVolcanic eruption cannot be stopped. Eruption prediction is an inexact science at best. Safety is in distance. Tourist beware.

Eruptions have many effects, both good and bad. A major eruption will blow rock, gases and ash into the air. Sometimes melted glacial water mixed with falling debris can cause mudflows in rivers and streams that are capable of sweeping away entire towns. In the short term (the time that the eruption occurs), this can be devastating. Indeed, many living organisms can die, including humans, plants, animals etc., and there can be some economical damage, including destruction of towns or villages, crops, water supplies and food resources. However, in a long period of time, through the force of erosion, volcanic material (particularly ash) will break down. This can form a very rich kind of soil, good for plant growth. Farmers in places near volcanoes can grow an incredible stockpile of good, fresh food because of the good soil.\nLava eruptions are far less dangerous than explosive ones (but lava flows can still pose as a threat). Though a lava flow is very hot and capable of burning anything in its path, it does not move very fast. These lava flows can vary in size, however, and sometimes a flow may destroy some plant life, as well as human settlements. Villages in Hawaii have been burried by lava flows, and there are articles in newspapers that show pictures of houses burning, or abandoned houses half-buried in cooled lava. But, like the explosive eruptions, when lava cools and breaks down over time, it too can form rich soils.\nAsh, an aspect mentioned before, is a volcano's legacy. The ash from a major eruption can travel around the globe in a matter of days. Ash, when seen under a microscope, consists of tiny, sharp particles. These particles can be extremely harmful to the human lungs, or the lungs of any other animal, for that matter. How would you feel if your throat and insides were scratched by miniature, sharp rocks? Ash can also be the opposite of a good soil maker for farmers. If too much ash covers a field, the field is ruined, for the plants will suffocate in the layers of debris. Sometimes, like it was with Mt. St. Helens, ash can pile up on top of roofs of houses, and any roof can cave in from the weight of it (just like snow). \nSo really, volcanoes make up a huge part of Earth in general, and they can have mixed effects on the environment.

4. D\nThe most explosive volcanoes are those containing a lot of silica.  The shape of the silca molecule is a bit like a pyramid which means that cannot move past each other very easily.  This makes them very viscous and so it takes much more energy to get it to move and the energy comes out in a single event.\n\n12. B\nIt's the difference between min and max.

1st answerer is good on location.  Difference between the types are due to the composition of the lava and where they occur.\n\nShield volcanoes, such as those found in Hawaii, have magma that is very low in silica, high in basalt (often referred to as "basaltic" volcanoes).  This means that the lava flows easily, instead of exploding.  That is why there is not a steep slope to the volcano and the biggest threat is just to remain out of the lavas way.\n\nStrato-volcanoes (Mt. St Helens) are found in subduction zones and produce a lava that is described as Andesitic (named after the Andes Mountains in South America).  This lava is high in Silica, which makes it much more viscous, and therefore, more explosive.  This explosiviness defines the shape of the cone, with much steeper sides.  With these types of volcanoes you have the explosive lava threat, but you are also threatened by pyro-clastic flows, and lahars.\n\nCinder cones are the same, compositionally as strato-volcanoes, but are not always located in a subduction zone, and are usually quite alot smaller.

I couldn't find any record of a recent volcanic eruption in Canada; however, there is a volcano in Alaska that is currently active.  The Augustine Volcano, about 175 miles southwest of Anchorage, entered an active phase on January 11, 2006 and is sending ash plumes as high as 25,000 feet into the air.\n\nFlights into Anchorage were temporarily suspended due to the ash cloud but have resume as of the evening of January 31.

A volcanic event can include\n\n(1) an eruptive pulse (essentially an explosion with an eruption plume, but also non-explosive surges of lava. A pulse may last a few seconds to minutes, \n\n(2) an eruptive phase that may last a few hours to days and consist of numerous eruptive pulses that may alternate between explosions and lava surges, and\n\n(3) a single eruption or eruptive episode, composed of several phases, that may last a few days, months or years (Fisher and Schmincke, 1984). Paricutin, Mexico was in eruption for nine years. Stromboli, Italy has been in eruption for over 2000 years.

A volcano is made by a solid that turns into a liquid and has the opportunity to rise through some kind of solid. It helps realism if it includes something like gas, because that is also part of a volcanic eruption.\n\nThere are several great ideas here:http://volcano.und.edu/vwdocs/volc_models/explosive.html

Several things happen when a volcano is about to erupt, some of the most obvious are: \n\n1.The number and size of earthquakes increase in and around the volcano. \n\n2.The ground deforms or "bulges" at the eruption site. \n\n3.A lot more gas comes out of the volcano.

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.

Disadvantages: destruction during eruptions,  magma flowing and ash clouds destoys everything on its way, earthquakes are frequent near active volcanoes.\n\nAdvantages: Volcanoes during eruptions throw out materials containing lots of minerals that turn into very fertile soils. After an eruption the land turns to be excellent for agriculture for many years. For example Greek and Roman civilizations settled on the fertile volcanic soils in the Mediterranean-Aegean region.

Iam not an American, but I think I am correct in saying that Mount Lassen is still an active  volcano,  it stays quiet for a number of years and then without warning it has a massive expulsion.I do know it is in a National Park and in an area of outstanding beauty.
