The impacts of a tsunami are dependent on many factors. Firstly population density around the coast area, if there is a high population density there is more likely to be more causalities and more people houses are more likely to be destroyed or damaged. However the extend to which peoples houses will be destroyed is down to the buildings design. In japan they have built Earthquakes are one of the most destructive natural disasters.
The impact of this event is one of the most traumatic ones because it can put long term effects on a large area. They are proven to be unpredictable but once it strikes, all in a few seconds, cities and towns are completely flattened.
Continue on to discover more about this dangerous calamity. Did you ever know that the earth can also move and come alive? Some plates slide past each other while some move apart.
Whenever these plates move along faults, stress builds up and gives a sudden release of energy that creates seismic waves. The waves then spread out and create what is called, an earthquake. Hundreds of earthquakes happen every day around the world. More than 1,tremors rattle each year but only aboutcan be really felt. Fortunately, the bigger earthquakes that you can feel happen less frequently and often occur away from inhabited areas.
When some deadly earthquakes hit populated areas, the aftermath is a lot of widespread damage. They can get as bad as what hit Chile in The largest For example as two plates move towards each other, one can be pushed down under the other one into the mantle.
If this plate gets stuck it causes a lot of pressure on surrounding rocks. When this pressure is released it produces shock waves. These are called seismic waves. This is an earthquake.
The waves spread out from the write my dissertation uk help where the earthquake started - the focus. More damage is done near the focus. The severity of the local effects depends on the complex combination of the earthquake magnitude, the distance from the epicenter, and the local geological and geomorphological conditions, which may amplify or reduce wave propagation. The ground-shaking is measured by ground Earthquakes An earthquake is a shaking or trembling of the crust of the earth caused by underground volcanic action or by the breaking and shifting of rock beneath the surface.
The volcanic action and shifting rocks create strain which continues to build to a sudden release of pressure resulting in a shock wave. However, bermuda triangle speech outline research as a result of this quake showed that some of the buildings in Los Angeles did not perform well, these included multi storey wood frame buildings and those with a weak first floor.
Therefore, from this conclusion it can be argued that the damage to certain buildings was due to human factors including poor planning for the structures of buildings. The Sichuan earthquake typical page count for phd thesis China occurred at 2: The timing of this earthquake meant the impacts were already worsened regardless of the human factors.
Because of the time that the quake occurred, many children were at school and most adults were working. Therefore this made them more susceptible to extreme impacts.
Other physical factors that worsened the impact include the shallowness of the epicentre at only 19km, in addition to this the terrain in central China is very firm, this means the seismic waves can travel long distances without losing much power. All of this evidence would suggest that the impact does not depend primarily on human factors as there are so many other aspects that contributed. However, there were also many human factors present in the earthquake in China, for instance thousands of school children died and this was mainly due to poorly constructed schools throughout the area, at least schools collapsed causing many child fatalities.
This is considered one of the most prominent and important impacts of the Sichuan earthquake as many families in China adhered to the One Child Policy, thus the badly built schools meant many parents lost their only child having a knock on effect on future generations.
Therefore some of the most important impacts did depend on human factors as if the schools had been built better; the extent a letter of job application child deaths could have been reduced significantly. It is difficult to argue convincingly that the impact of human hazards depends primarily on human factors as in every case there are always numerous factors that contribute to the extent of the earthquake.
The easy route would be to argue that less developed countries are impacted more seriously by earthquakes due to human factors such as poorly built infrastructure and high population densities however this is not necessarily the case as in L.
But, all impacts of any case study cannot be proven to be as a result of human factors, thus it is impossible to argue that the impacts of earthquakes hazards depend primarily on human factors.

This can depend on many different aspects, for instance the level of development in the relevant country, the standard of infrastructure, the magnitude and location of the quake and lastly what time the model letter of application occurs. In order to properly assess whether the impact of earthquake hazards depends primarily on human factors, it is necessary to look at a range of case studies which will provide a balanced overview.
For instance — looking at the LEDW — examples such as the Haiti earthquake in January as well as the earthquake in the Indian Ocean in December could suggest that the impact depends primarily on human factors as these countries are not fully developed and thus might have underdeveloped infrastructure and building regulations.
Contrary to this, the MEDW with examples the impact of hazards essay as the Northridge earthquake in could provide a contrasting argument in terms of how human factors affect the impact.
