Discuss the view that poverty is the real killer in earthquake disasters. (40 marks)

Seismic events prove that it is a problematic for the world’s population and produce devastating effects on the lives of everyone involved. However it is often said that LEDCs suffer much more from the effects of earthquakes than MEDCs. Whilst this is a generalisation it is probably true, at least in terms of the human cost. Poverty is the condition of lacking basic human needs such as nutrition, clean water, health care, clothing, and shelter because of the inability to afford them. There are several levels of poverty from an individual to national level and earthquake disasters impact at all levels. The 2010 Haiti earthquake struck in the most densely populated area of the country, As More than 78% per cent of Haitian residents live in poverty and Haiti is the poorest country in the Western Hemisphere the buildings in Port-Au-Prince and other areas of Haiti were in very poor condition in general and were not designed or constructed to be earthquake resistant.

 

The primary earthquake hazard directly responsible for mortality is surface seismic waves which cause ground shaking. This poses a huge hazard as buildings and other structures collapse, killing or injuring their occupants. This was the case in Sichuan, China in 2008 where severe ground shaking was the direct cause of death, injury and the catastrophic destruction of hospitals, roads and other infrastructure. An estimated 5.4 million buildings collapsed and a further 21 million were damaged. In poorer areas such as rural China, buildings are compromised despite strict regulations due to poor quality construction work and corruption meaning the correct materials is not used. Since 1976 China has had a stringent earthquake building code. Before the quake, millions of buildings in Sichuan pre-dated the 1976 code. These older buildings were mainly low-rise masonry constructions without steel reinforcement. Without it, buildings are brittle and easily snap and collapse. In Sichuan, building failure was due to a combination of severe ground shaking, poor design lacking in steel reinforcement and the use of inadequate construction material, including inferior concrete. The reason behind such high figures was due to poor design and cost-cutting construction. Concentrated mainly in poorer rural areas, these buildings were the most vulnerable and simply collapsed in the quake, this was also the same situation for the 2010 Haiti Earthquake. The earthquake caused a massive devastation impact as the city is built on loose sediments. The depth of the earthquake in Haiti was very shallow, meaning that the energy that was released is very close to the surface, which causes some violent ground shaking. How individuals and the emergency services react during and immediately after such hazards can play a big role in reducing the death toll.

Secondary hazards can prove just as fatal and include landslides and soil liquefaction. The result of liquefaction is that building foundations become unstable and slopes become vulnerable to mass movement. As people living in poverty cannot afford the materials to build homes with high quality foundations and many live in squatter settlements or slums they are particularly vulnerable. The location of buildings is often determined by the funds available when planning takes place. In LEDCs where there is civil strife governments are more open to corruption and allow building on areas of land that are unsuitable. Slums often develop ...

This is a good answer to a question which many students would find challenging. The author has introduced many of the key ideas, although the way this has been done could be improved upon. Some of the key concepts could have been explained in the introduction, which would have improved the structure overall. As this question is about deaths from disasters, the author should have used more figures for death tolls in the answer.
