Analyse the factors that cause differences in the hazards posed by volcanoes around the world (40 Marks) A hazard is a potential situations that we, as a race, perceive as a threat to life, whether that be in respects to death, health or even economically. We perceive, from historical experiences and scientific study, that volcanoes pose a hazard to our life via periodic eruptions that take place. However, there is clear variability of the damage, or level of hazard, that these volcanic events cause. This can be down to a number of factors. For this, an analysis of the controlling factors must be made, such as the settlement of the area, the composition of the volcano and the economic status of the area that is affected.
This could be a problem if an eruption was to take place at the Yucca Mountain or close by. An eruption could cause damage to the facility or in the worst case magma flowing through the facility which could damage canisters holding radioactive
Reducing ground water levels will have consequences on the wider ecosystem and it will affect wetlands. Drilling in the Gulf of Mexico could damage the sea bed and even destroy ecosystems not even discovered yet. Also conflict over who will get the oil in the Arctic will be in dispute and will most likely be economically costly and large social conflicts with tribesmen there and
Throughout Appalachia this process has been occurring, and has lead to outrage among many people across these areas, and even the nation. This type of mining has been in effect for years, and has been effective in retrieving large amounts of coal, that is used to power our nation. While coal is a necessary source of energy in the United States, opponents of this technique argue that there are many negatives to mountaintop removal. These negatives include the destroying of ecosystems, the pollution of the nearby streams and rivers, pollution of the air, numerous health affects, and of course the
As a result many LEDC countries such as Chile often experience the effects more severely than those in MEDCs such as Italy. In June 1991 on the Island of Luzon in the Philippines, Mount Pinatubo erupted where 500,000 people lived within the danger zone of the volcano. The Philippines is a LEDC, which relies heavily on sustenance farming, as a result the effects of this eruption severely affected the people. 847 people died directly from the volcano and 500 more from the indirect effects of the eruption. During the time the USA had used the Philippines as a military base and thanks to this they provided financial support.
A hazard is a natural event that has the potential to effect both life and property. When looking at earthquakes there is one primary hazard which occurs and this is the shaking of the ground. In addition there are many secondary hazards such as landslides, fires, avalanches, liquefaction and tsunamis. There are many human factors to be discussed such as preparedness, development level, land use and education and many other contradicting factors such as the tectonic setting and the time of year. To show the view that the impact of earthquake hazards depends primarily on human factors, I will situate the essay around some seismic events that have previously occurred; Haiti in the Caribbean, 2010, Christchurch in New Zealand, 2011, Sichuan in China, 2008 and Indian Ocean, 2004.
Volcanoes and earthquakes In the world, there are many natural disasters which occur without the human's contribution. Volcanoes and earthquakes are some disasters that have a huge impact on many things. These two types of natural events can compare or contrast to each other. These natural disasters have differences more than similarities. Volcanoes and earthquakes are different in three things: the geology, the process, and the effect.
For example in areas of Nepal, they cut down the vegetation to provide wood for heating and construction, the fertile topsoil is eroded by rain because it is now without the protection offered by natural vegetation. The hillside fields then become unproductive, incapable of supporting the people who have settled there. Because they didn’t carefully develop the vast forest area, they lost the land now. In the World, some countries used tropical zones to provide employment and earn money from exports. Because overexploitation of tropical forests affect the global climate.
Oil spills have a number of effects on the environment and economy. On a basic level, oil will damage waterways, marine life and plants and animals on the land. An oil spill can also ruin the infrastructure and economy of a particular area with the long-term effects being felt for generations. Cleaning an oil spill is very expensive and the costs get spread to government agencies, non-profits, and the oil transport company itself. There is no set science for an oil spill clean-up.
They lose their habitat and forced to move to new location; besides, many cannot survive the deforestation that destroys their homes. It is undeniable that deforestation itself has extreme effect on Global warming and hurts the air. Global warming means that air and ocean temperature is increasing. Greenhouse gases exist primarily because of human activity. Unfortunately, humans are the most polluting species on the planet.
