Icelandic Society Essay

To what extent can preparedness and planning mitigate the effects of a volcanic hazard (40 marks)

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 Norse tale of Ragnarok presents an interesting example of apocalyptic literature by providing both an end and a unique beginning. The world which rises from the cosmic rubble seems to be essentially equivalent to that which the apocalypse destroyed, possessing the same creatures, features and Gods of times past. This considered, and by incorporating themes of time and fate, Snorri challenges the concepts of the past, present and future of Norse lore by providing a framework which allows for the potential reiteration of history. By reviewing The Prose Edda’s telling of the events surrounding Ragnarok, the relationship between fate, time and history provide a unique alternative to the standard eschatological timeline.

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 human factor that would cause differences in the hazards posed by volcanoes is settlement, which includes where people chose to live in relation to a volcano. For example, in Indonesia many people settle near Mount Merapi because of the rich and fertile soil favoured for farming. As Indonesia is a poor country many people rely on subsistence farming, therefore are willing to risk everything by settling beside a volcano. Furthermore, in the last eruption in 2010 360,000 people were displaced from their homes, meaning not only did they lose their home but also their livelihood; hundreds also lost their lives. Therefore, the hazards posed could have been minimalised if people chose to settle elsewhere.

How did the described volcanoes in Iceland and the Philippines change the environment to lesser or greater extents?

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.

Ash plumes and steam rose into the bright blue sky as the underground earthquake shook the land and rattled windows all across the eighteen mile town. As the jet circled the island, in view of lovely beaches and emerald water, looming over this lush paradise was the screaming volcano. Volcanos erupt when the pressure inside of them becomes so great that the magma surges up and forces its way out. An exploding volcano can rip apart a mountain in just seconds, when the eruption is over, a landscape is changed forever. The united states is home to more volcanos than any other country except Indonesia, and Japan. The majority of these volcanoes are in Alaska. Until recently, there was no way to predict when a volcano would blow, although volcanoes give off many warning signs before they erupt. Including smaller earthquakes beneath the volcano, slight inflation, or swelling. The rising magma eventually causes the solid rock to break, sending earthquake signals. Most volcanoes give warning signs beginning weeks or months before they blow (Lindop).

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.

Volcanic eruptions are a constant issue. There are around 50 -70 eruptions every year with some volcanoes erupting more than once. Around 35 people die every year from volcanic eruptions along with an average cost of damage of 98,992,000. I believe that with a little math that these numbers can go down. Issues with volcano causing so much death is more of the debris that comes out of it if we could estimate the distant that this debris could travel then we would simply need to change the areas that we build cities and how far we would need to evacuate in a sudden emergency. This will include the ideas of projectile motion, angular projectile motion, Geometrical estimations. For this example, I will be using the volcano Mount Vesuvius. This volcano is known best for the destruction of Pompeii and villages that surrounded it. This eruption works the best due to the easily known eruption and the easily measurable distances from Pompeii to the center of Mount Vesuvius.

The country that I choose is Iceland. Iceland is very unique and interesting not only because of its clean air and amazing scenery but also its natural beauty and landscapes. Nature is a big force of Iceland but the volcano’s, waterfalls, and glaciers seem to attract most tourist. There landforms are probably the most unique. The Northern Lights is also something that people find very interesting because how it is created and the view you can see. It is something that everyone should see at some point in their life. The sources that I choose to use to research the Physical Geography, Economics, History, Cultural, and Political

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.
