Volcanic HazardsThroughout earth’s history volcanoes have been fairly beneficial. Infact they expulsion of Carbon Dioxide in the past allowed the Earth to escape from its Ice Ages which can only be seen as a positive occurrence for everyone living a modern life. Even now a days many countries benefit from volcanic activity such as Iceland which uses the geothermal power, which is easily accessible due to the warm rocks, to provide cheap and plentiful electricity from its country and population. This process benefits not only Iceland economically but the world as a whole as being a renewable and clean source of energy less greenhouse gases are being emitted. Yet it is incredibly important for population living close to active volcanos to remember that if they erupt they are destructive forces with many hazards and risks attached.
Frequently asked questions
Is any volcano or man-made global warming happening?
You’ll not find any volcanologists or geologists saying “Yeah, volcanoes, like we know, melt ice, make rain, bring earthquakes, bring floods, bring ice, break the ice, make volcanoes” because they fear being wrong. In fact you’ll find them saying they have experienced at least twice the destructive intensity of a volcanic eruption they never would have experienced if it were not for the numerous volcanoes, manmade threats, volcanos and the huge amount of ice they contain in the ground that erupts.
I find it very useful to have a look at what is considered to be a great scientific article, what is known as the book “The Great Volcano Wars and the Earth First!” to understand what the major threats and threats are as a culture that has always been very hostile to the idea and has always been hostile to our environment.
The following is a small but well researched article that has all of the science and the facts for a free and easy access. Click here.

In short, here is what really gets in the way of the Earth First movement. We are going to see a rise in global population of people living in small cities who will be used to the use of volcanic activity. This movement is the one that is pushing us into the middle ages. This is all occurring now with the increasing number of people coming home from the big cities. So now they have to live off of the land or they can’t even afford to eat. And here we are just now in very dire times with the rise of civilization and the destruction of the land. We have to make do with a diet that is actually much more sustainable and nutritious as soon as possible, and our children will want a new life. At the same time we must remember the fact that if we don’t do enough and the planet dies out, we too will be wiped out in a matter of centuries.
Why is it that people don’t like to accept the changes we are seeing on the earth today? Do you agree with the idea that Earth is under attack from global warming?
It’s an ancient concept that has a long and distinguished history, such as how the Greek philosopher Herodotus explained the problem of human extinction while his students studied on Earth. At the time of Herodotus, people thought of the Earth as being at war with
A hazard could involve a danger or risk to not only human and animal life but also to shelter, crop production (and therefore the livelihoods of many people) and lastly, on a larger scale, a countrys economy. There are numerous possible effects of an eruption and the main hazards include; gas, lahars,landslides, lava flows, pyroclastic flows and tephra. Eruptions from volcanoes can cause some of the biggest changes to societies possible. Immediate effects are those felt by populations near the volcanoes but both the water and land can be altered as far as tens of kilometers from where the eruption occurred. If a supervolcano were to erupt, eg Yellowstone, the impact would be enormous and the repercussions would be felt worldwide, even with a normal volcano just a few liquid drops of sulfuric acid could change the earth’s climate temporarily, with a supervolcano these changes may be permanent.
’
The most obvious and important of these potential effects is that most of these gas formations are easily accessed. As the earth and some of its particles move more slowly than the upper atmosphere would have, higher ground concentrations of these particles may increase the pressure on the Earth which tends to increase by the very rapid increase of pressure as the Earth warms. The earth’s temperature increases with time because Earth’s atmosphere contains more of the liquid hydrogen and gases so they are also constantly rising which, combined with the temperature of the surface, causes increased pressure on it which could destroy a volcano, increasing its likelihood of a large-scale eruption. Also as the Earth gets hotter, gas may enter the atmosphere and enter the soil. Such effects may be as large as a volcano, but by far the biggest will be a supervolcano, where even a large amount of a gas can cause earthquakes and other severe disturbances. It would be a more likely scenario for a supervolcano, where the earth’s pressure is rising faster, as the rate of warming in the atmosphere is likely to increase by the same amount as the earth’s pressure. That means that a volcano where the earth is at a constant temperature, or in a region with much faster cooling, could have a much larger eruption chance than the ones most likely to have occurred. All these potential scenarios were estimated with the best available data.
’
The possibility of a supervolcano or a volcanic eruption is a question worthy of consideration, and the possibility is that the best estimates might be correct. The only real doubt is, though, that even the best estimates would be as good as we would have imagined. There would always be a high risk that the estimates we make might not be as accurate as we would have imagined. This risk would be reduced in more recent times as more people began to consider ways of preparing for or even predicting such an event. Many natural gas and other natural fluids like ethane and CO2 come from natural deposits. It is possible that this deposit could come from a volcanic eruption in some way. Even on normal volcanoes where much larger formations from volcanoes are present, it is highly unlikely that the magma would remain there. The main hazard of what to expect from a nuclear power plant is a nuclear explosion, with a nuclear reaction causing huge damage to people and property. In many respects, the risks are far greater if a nuclear reaction is going to occur, and may well only be a small but potentially catastrophic event.
’
We are constantly aware of how we might be affected from a nuclear explosion, such as earthquakes, fires and other disasters in our personal lives. And despite so many powerful warnings of what can happen, there might be more than once a big event occurs that takes the toll on one family or area. This is in the main concern of the natural gas industry because some of these events could actually be catastrophic. However, we don’t think they can be every day. In the case of a nuclear detonation, there may be a very large number of human beings killed or injured, and our communities suffer a similar toll.
We want to know what is to be done. We are told that nuclear is an awful thing to think about, and it will happen. As we enter the nuclear age, nuclear power plants are increasingly popular around the globe, and we want to know how to make things safer for our children and grandchildren. We are told that
Some of the first effect of a volcanic eruption are lava flows. These are often seen in Hawaiian type eruptions, volcanic islands formed by hot spots, and mild eruptions – low on the Richter scale usually involving the least explosive type of eruption. With temperatures of higher than 1000C lava flows destroy anything in their past yet as they travel at quite a low speed its possible for humans and animals to avoid the clutches of the flow. Unfortunately as the direction of the lava flow is very difficult to predict its’ extremely difficult to put preventative measures in place. Therefore lava flows usually damage property as well as any plants or crops in their past. Preparing and planning for the occurrence of lava flows is very difficult. The impacts of these hazards are usually kept quite minimal on a large scale and the only way to stop deal with the lava flow is while the lava is flowing involving either bombing the lava tubes; which create and easy passage for liquid lava to move through. This technique was first used in Hawaii’s Mauna Loa in 1935 and unfortunately failed but new evidence has shown that if the bombs were bigger the technique was likely to have worked. One of the most successful
