Eyjafjallajokull's Effect On The Environment

Assess the extent to which primary rather than secondary impacts are the more serious effects arising from volcanic eruptions. (30 marks)

A hazard is a situation that poses a level of threat tolife, health, property or environment. The level of hazard posed by different volcanoes can very greatly, from a weak eruption with minimal impact that causes little damage, to a voilent and life threatening explosion. Most of the sixty-plus volcanoes that erupt each year are low risk, however a combination of factors can cause a volcano to be a serious hazard. The factors causing these variations will be explained in this essay.

The volcanoes are located where there is a divergence or convergence in the tectonic plates and bring their lava from the deepest of the terrestrial mantle. The materials and explosions of these ginates represent a constant risk in the places inhabited by the human being, nevertheless the people ususually live in these areas no matter the risk. On the other hand the volcanos can change the geology of an impressive form, or to cool the temperature of the earth, or to darken the sky. The scientific community increases its efforts to try to understand better what happens in volcanoes, however it is impossible to predict these conditions.

Volcanoes are one of the most destructive, yet, most beautiful things on Earth. They can make a famous city choke in its own ashes in one day, like Pompeii. Or they can turn a once damaging mountain into a graceful and peaceful home for new life, like Mount St. Helen’s. All volcanoes are unique, and no two are the same. Some erupt differently than others, some look different than others, and all are located in different spots all over the world. I learned this while completing the project and the five volcanoes I researched are examples of my discoveries. The five volcanoes I researched were Mount Hood, Mount Mageik, Long Island, Mount Muria, and Las Pilas.

Another physical factor is snow; if a volcano is snow capped, like Eyjafjallajokull, then the lahars and flash floods become a greater hazard. The flooding in Iceland in 2010 caused 700 people to be evacuated. Without the snow then lahars and floods may not be a problem at all.

A hazard can be define as something which poses a level of threat the life, health, property or environment, a volcano can compromise all these things through the many hazards volcanoes presents. Such as lahars, flash flooding, landslides, pyroclastic flows, ash clouds and many others. There are factors which can influence the severity of the hazard and cause differences in them and can be classified into different categories, such as physical, economic, political and social.

Mauna Loa volcano. Mauna Loa is an active, large, and dangerous volcano in the world.this volcano can cause more than one damage. Mauna Loa affects people’s lives, and damages lands. Mauna Loa is a magnificent force of nature.For centuries Mauna Loa has captivated many discoverers and scientists all around the world.But some, however got injured by Mauna Loa and didn’t study its parts.One discoverer however actually discovered it somehow.This volcano is very dangerous and it can damage 1 small village.

Albeit no emissions of magma or volcanic cinder have happened for some a large number of years, future ejections are likely. In the following few hundred years, risks will most likely be restricted to continuous fountain and hot-spring action, incidental steam blasts, and moderate to vast quakes. To better comprehend Yellowstone's well of lava and quake risks and to help ensure people in general, the U.s. Geographical Survey, the University of Utah, and Yellowstone National Park structured the Yellowstone Volcano Observatory, which persistently screens movement in the

that the volcano must be classified as dormant rather than extinct. Moreover, the unexpected 1995 eruption of the Soufriere Hills volcano on Montserrat, situated in the same volcanic arc, demonstrates that continuous awareness of the associated hazards is required.

How many volcanoes are going off right now? What are these volcanoes doing to the environment and to the people? So, how do volcanoes shape the earth? Volcanoes can be harming but, what most people don’t know is, they can be helpful too. One way they can be helpful is because they put off certain minerals in the ground that can help plants grow faster and better because, it enriches the soil over time. Another, instance in which they are helpful is because, they put so much nutrient in the soil they provide a safe haven for rare plants and animals after they have erupted and cooled. One, instance they can be harmful in though is because of how much of them may be going off at once. There are many ways that volcanoes help to shape the earth.

Many people underestimate the power of volcanoes and the amount of damage they can do to a country, state, city, or town. A volcano is a mountain that extends down to a caldera which is a pool like are of magma in between the mantle and the crust in the Earth. It in a sense is a massive hole in the middle of the crust and mantle of the Earth where magma can erupt from and eventually make its way to the Earth’s surface. Volcanoes are estimated to kill almost 1,000 people per year and caused $99,000,000 worth of economic damages from 1980 to 2008. When an active volcano erupts its “danger zone” is about a 20 mile radius around the volcano itself, which ends up killing people, destroying houses, land, etc.

In these eruptions, instead of the mixture of gas and ash flowing upwards, it flows outwards and hugs the ground. These eruptions are extremely dangerous.

How volcanoes affect people and environments? A volcano is a mountain or hill having a crater or vent through which lava, rock fragments, hot vapor, and gas are in. Volcanoes can change the weather. They can cause rain, thunder and lightning. Volcanoes can also have long-term effects on the climate, making the world cooler.

Recently there has been a lot of research in the field of climate change, and much of it is focused on anthropogenic affects on climate. However, there has also been a great deal of research focused on natural Earth processes and how they affect the climate (Robock 2000). One natural process which significantly impacts climate is volcanic eruptions. Volcanic eruptions affect the climate of the earth in many ways (Zielinski et al 1997). Volcanic ash ejected during eruptions effect climate by reflecting solar rays back into space, and thus cooling the surface of the Earth. Another way volcanoes affect the Earth’s climate, is the emission of many different types of volcanic gasses.

Since the dawn of history, volcanoes have been an awe inspiring feature of the earth that has frightened and intrigued mankind. Volcanoes have taken the lives of over 250,000 people in the last three hundred years and changed the lives of millions of others, but up until recently humans have had very little understanding of the volcanic processes that presage an eruption. The advent and implementation of new technologies and scientific methods has allowed us to begin to comprehend the inner workings of one of nature's most powerful forces. Through understanding how volcanoes work, volcanologists hope to accurately predict when an eruption may occur, what the magnitude and type of eruption will
