In theory, this is easier for MEDC’s due having more advantaged technologies and more money available to spend on monitoring the ‘danger zone’ and then warning and planning for the hazard. However in some situations it isn’t the primary effects of the earthquake or eruption that have the greater impact, therefore not even MEDC’s can plan for it. For example in the 2010 Eyjafjallajokull eruption in Iceland, it was not the primary effects that caused problems, it was the ash cloud which was produced after the event. The Icelandic volcano, Ejajjallajokall, affected many people around the world, both wealthy and poor. The cloud caused problems for all over the world, which lead to most of the airspace to be closed.
'The extent to which volcanic processes represent hazards depends on where and when they occur.' Discuss this statement. Volcanic processes become a hazard when they impact upon the human and built environments, killing and injuring people, burying and collapsing buildings, destroying infrastructure and bringing agricultural activities to a halt. Volcanic hazards are influenced by several factors including location, time and frequency of eruptions, and the materials ejected. It is the viscosity of magma that largely determines the nature and power of an eruption and the resultant severity of the hazard.
Analyse the factors that cause differences in the hazards posed by volcanoes around the world (40 marks) A hazard is a situation that poses a level of threat to life, health, property or environment, all of which can be compromised by a volcano. A volcanic eruption can cause many deaths, illnesses, destruction of property, crops, and livestock, also the economy of an area may be affected, amongst other things. However, there are many factors involved which can cause differences in the severity of destruction caused by a volcano such as, settlement, monitoring, plate boundaries and the economic status of a country; which would be different for every single volcano around the world. One 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.
Analyse the factors that cause differences in the hazards posed by volcanoes around the world (40 marks) Volcanic hazards pose a risk to people and their property in both primary and secondary form. A volcano is an opening in the Earth's crust which lava, ash and gases erupt. A volcanic eruption can cause many deaths, illnesses, destruction of infrastructure, crops and livestock, all which will affect the economy and GNP of a country. There are many factors involved which cause differences in the severity of the destruction caused by a volcano, such as, locations of settlements, monitoring, plate boundaries and the economic status of a country, however these are different for each volcano around the world. I will be discussing factors that cause differences in hazards posed by volcanoes.
The scale or better known as magnitude of the earthquake effects these characteristics and determines the physical destruction. The local geology of the area such as whether building on reclaimed land can have huge toll on building destruction and impact on hazards. Along with this the proximity of the earthquake to the coast can have a huge impact on the hazards. If the earthquake occurs out at see the tsunamis can be just as devastating if not more destructive than the earthquake. It would result in services being unable to reach areas due to the flooding and many more lives could potentially be lost.
“While [hydraulic fracturing] can help provide energy for America's future, it also poses a new dangerous threat to wildlife and the environment. Toxic chemicals are used during fracking that can infiltrate and contaminate habitat, waterways, and even the drinking water that people and wildlife depend on” (1996-2013). Evidently, “some opponents of oil and natural gas production claim that fracking has serious environmental consequences. The truth is, while all development has challenges, hydraulic fracturing technology has a strong environmental track record and is employed under close supervision by state, local and federal regulators. Studies by the Environmental Protection Agency (EPA) and the Ground Water Protection Council (GWPC) have confirmed no direct link between hydraulic fracturing operations and groundwater contamination.
One of the greatest advantages of nuclear power is that it avoids the wide variety of environmental problems arising from burning fossil fuels such as coal, gas and oil. Currently 78% of Australia’s electricity comes from burning coal. Nuclear energy does not produce smoke or carbon dioxide, so it does not contribute to the greenhouse effect. Thus ‘global
To what extent can preparedness and planning mitigate the effects of volcanic hazards? (40 marks) Volcanic activity happens across the surface of the globe and naturally hazards occur too. A hazard is a situation that poses a level of threat to life, health, property, or environment. It is easy to locate volcanoes, but it is very difficult to predict exactly when activity will take place, particularly a major eruption, this makes it difficult to prepare or plan for one. There is a very big difference that helps prepare for a volcanic hazard and that is whether you are in a MEDC or a LEDC.
I think that America is truly one of a kind because not only does it offer many chances for people to start a new life, it is also different from every other country due to its customs and traditions. In my country, Uzbekistan, we don’t celebrate as many holidays as an American person would celebrate, which is exciting for me to take a part and learn about a new
* why a volcano erupts, and what happens afterwards; * what happens after a loved one's death. The below example shows a cause essay, one that would explain how and why an event happened. If this cause essay were about a volcanic eruption, the thesis statement might go something like:"Pressure and heat built up beneath the earth's surface; the effect of this was an enormous volcanic eruption." The next example shows an effect essay, one that would explain all the effects that happened after a specific event, like a volcanic eruption. If this effect essay were about a volcanic eruption again, the thesis statment might go something like: "The eruption caused many terrible things to happen; it destroyed homes, forests, and polluted the atmosphere."
