Globally Vulnerable To Volcanoes: The Globalized Contemporary Society

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.

A volcano is an earth hazard that occurs on faults between tectonic plates on a destructive boundary and an eruption is a natural disaster. A primary impact happens immediately after the disaster and before any response like death or collapsing or destruction of buildings. A secondary impact occurs later after the disaster, such less farm produce or a reduction in tourism. The severity of these impacts will differ considerably in a MEDC and LEDC where volcanic eruptions have taken place. These may be seen in the Mount St. Helen volcano eruption as well as in the Iceland volcanic eruption. They may also

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 in fact important because without volcanoes the atmosphere wouldn’t have its oxygen rich properties. Many of years ago, Earth’s atmosphere was swarm with rock-forming minerals of the earth 's crust. During earlier volcanic eruptions many gasses enters into the earth atmosphere. Carbon dioxide, water vapor and many other gases

Volcanos are beautiful yet discursive. They may have different effects on towns but some are similar, and some are different. Some may have an effect on both people and cities and the people's mindsets may change on their beloved homes.

Though volcanoes can be very harmful they also help the environment and its nature. According to Russel Mcdonaugh, author of the article, he states, “Once volcanic deposits have been broken down, they enrich the soil both by adding important nutrients for plants and by providing excellent drainage.” (60). By adding nutrients to the soil, the deposits of the eruptions strengthen the soil and causes it to have positive effects. Some of these positive effects include nurturing

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.

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.

Something beautiful can also be dangerous, as like the darkness can have phenomenal results. Volcanoes are one example of nature’s beauty, they can be fascinating, exciting, magnificent, but they can also be catastrophic. Their hazard eruptions put many lives at risk, destroying properties, places, and can disrupt air quality. The list of volcanoes is huge, there are three groups of them, dormant, extinct and active volcanoes. From the latter group there are about 500 in the entire world. Although both Mt. St Helens and Mt Pinatubo are two of the most significant volcanoes in the world, they have some characteristics that show their differences and similarities between both of them.

The Earth’s outer crust is made up many tectonic plates that move over the surface of the planet. When the plates come collide, volcanoes will form sometime (National Ocean Service). Volcanoes can also form in the middle of a plate, where magma rises upward until it erupts on the sea floor, at what is called a “hot spot” (National Ocean Service). A hot spot is a plume of magma or molten rock that rises from within the Earth then reaches the surface forming underwater volcanoes which may grow tall enough to

To begin, a volcano is a mountain with an opening in the top or side that sometimes sends out rocks, ash, lava, in a sudden eruption (Merriam-Webster, n.d.). A volcano erupts when pressure builds inside the mountain. Magma, lava while it is inside the volcanoe, pushes through the weakened crust. When this built up pressure is released, Earth’s plates move causing a volcanic eruption. Also, dangerous flows of steaming lava can reach up to 2,000

A volcano is defined as a vent in the earth's crust through which lava, steam, ashes, etc., are expelled, either continuously or at irregular intervals. These natural disasters can cause extreme amounts of damage and have taken the lives of many people. Around the world approximately 35 volcanic eruptions occur each year and have taken the lives of 27,433 people since 1980 (Statistic Brain 2017). According to the National Center for Environmental Information since 1956 there have been ten significant volcanic eruptions in the country of Russia, two of which resulted in a tsunami (NOAA Significant Volcanic Events Database). In this essay I will be discussing the geographic and tectonic location, history of eruptions, history of volcanic impact

The media has engendered the critical opprobrium of volcanoes with their triumphant essays at delineating volcanic eruptions so as to give the impression that they are devastating and precarious. As a result, the negative stigma encompassing volcanoes and their concomitants permeates all walks of life. Under the nourishment of ignorance and fear, which are constituents of the human condition, antipathy multiplies. Ergo, Homo sapiens, possessing complex cognitive neural processes, are predisposed to the fallacious notion that assumes volcanoes have deleterious effects on the progression of humankind. The precise definition of the term volcano is profoundly convoluted, as a myriad of labyrinthine systems engage in volcanic activity. On loci where
