Discuss the view that the impact of the earthquake hazards depends primarily on human factors? An earthquake, a sudden violent shaking of the ground can be caused by a number of things from seismic activity and resulting in varying impacts. The cause of an earthquake are a result of built up pressure under the earth’s crust, the pressure comes from the movement of the tectonic plates, they can occur on any plate boundaries. Although the majority of the earthquake hazards come from the physical factors, human factors can determine the severity of the event. The impacts created from an earthquake can come from the physical factors of the size, the location of the epicentre and the surrounding areas such as a ground type and the lithology of the rocks. However they can also be influenced by human factors such as land use of an area, population density of an area and the use of technology or the equipment a country have that can monitor the event. By this they can prepare or plan for such a disaster. In my essay I shall discuss how the impacts of the earthquake hazards aren’t always human factors and can vary with different events. I shall use examples of the Kobe Earthquake 1995, Boxing Day Tsunami 2004 and the Haiti Earthquake 2010. The earthquake of 2004 was caused by subduction of the Australian plate and the Eurasian Plate ,a 15-20m slip occurred along the fault line which then caused an earthquake measuring a 9.1 on the Richter scale. This a very high recording on the Richter scale so therefore it would always cause devastating hazards , but human factors could be seen as making the impacts far worse. The earthquake in the ocean had caused a tsunami to occur within the Indian Ocean. The wave reached up to 30 metres high causing devastation to the 13 countries surrounding the ocean. A key drawback to the event was the lack of preparedness and communication
