A ‘hazard’ can be defined as a geophysical process operating within the lithosphere‚ atmosphere‚ hydrosphere or biosphere which could potentially lead to the loss of human life or property. However‚ an earthquake only becomes hazardous and therefore needs management if it occurs within close proximity to a vulnerable population. To some extent‚ any human settlement around the world situated close to or on top of an area of seismic activity is vulnerable. However‚ not all nations suffer equal devastation

Discuss the view that the impact of earthquake hazards depends primarily on human factors (40 marks) Earthquakes are an example of seismic activity caused by the build-up of tension at the three types of plate boundaries: destructive‚ constructive and conservative. The pressure is suddenly released as the plates jerk past each other‚ sending out seismic waves from the focus that travel through different parts of the earth. The movement of convection currents within the Earth’s mantle causing the

of plate tectonics help to explain the world distribution of earthquake and volcanic zones? The Earth’s crust is made up of seven major plates and several smaller plates. These plates drift on top of the mantle. When two plates meet‚ they can either be constructive‚ destructive or conservative. At a conservative plate margin‚ one plate moves past another. As the plates are not smooth‚ great amounts of tension build up and earthquakes are made when the tension is released and the plate moves. An

understanding of the distribution of either earthquakes or volcanic eruptions. Plate tectonics can help us understand the distribution of earthquakes and volcanoes very easily‚ it is recorded that main earthquake and volcanic zones are clustered along plate boundaries and more powerful ones are near destructive and conservative plate boundaries. Over time we have learnt that earthquakes that occur on a constructive plate boundary cause little hazard to people‚ earthquakes that occur on two oceanic plates
