‘The hazards presented by volcanic and seismic events have the greatest impact on the world’s poorest people’ to what extent do you agree with this view? (40 marks) Volcanic and sesmin events and activities can take place all over the world and therefore both more economically developed countries (MEDCs) and less economically develop countries (LEDCs) can be affected. In the last 30 years there have been masses of examples of where volcanic and seismis event have had an impact on both MEDCs and LEDCs. Although prevention of either an earthqauke or volcanic eruption isnt possible, it is possible to manage them and reduce the overall impact. This should, in theory, be easier for MEDC’s due to having more money available to spend on management polices. However in some situations it isnt the primary effect of the earthquake or seismic activity that have the greater impact. In this essay I will show how the impact of volcanic and sesmic events have a ‘greater impact on the world’s poorest people’ than on richer countries. The Jananese earthqauke occurred on the 11th of March in 2011. A massive 9.0 magnitude eathquake struck Japan, Friday afternoon at 5:46 local time, it lasted 6 minutes. This earthquake makes it the fifth largest recorded worldwide since 1900. The quake was centred 130 kilometres to the east of the prefecture’s captial, Sendai. The coast of Japan is highly built up and this in its self caused a massive problem. The seismic event caused a Tsunami, which was sent crashing into the country’s north-eastern coast. The reason behind this catastrophe was because Japan is located on the east edge of the Eurasian Plate, therefore the Oceanic Pacific Plate was subducted under the Eurasian Plate. This plate margin is known as a Destructive plate boundary. The reason behind the huge 9 magintude earthqauke is because when the Oceanic Plate was being subducted under the Eurasian Plate, tension was built up, the tension then became too much for the plates to...
