Discuss the view that the impact of earthquake hazards depends primarily on human factors (40) Plan: Intro –What is a hazard? - Human and Physical Factors – How to manage with events Main – Natural Hazards – Human Factors – Management – Case Studies –California 1994 –Gujarat 2001 –Indian Ocean Tsunami 2004 Earthquake Hazards occur when there are adverse effects on human activities. This can include surface faulting, ground shaking and liquefaction. In this essay I will be discussing the factors that affect earthquakes, whether human such as population density, urbanisation and earthquake mitigation or physical such as liquefaction, magnitude, landslides and proximity to the focus. Economic Development is one of the greatest…show more content…
Millions were made homeless by the huge waves that swept houses and cars away. It was estimated that the costs to repair all damage would be at approximately $5 billion. Another human factor is the earthquake mitigation through education and community awareness. Schemes such as the one in Sichuan, China helped to save thousands of lives. The weekly intervals of training in case of an earthquake, educated children and adults of what to do when the quake struck. Evacuation schemes such as the window slides or hiding under tables was reported to have saved thousands when the magnitude 8.0 hit the area in 2008. However, some were not saved due to their unwillingness to move and evacuate the area. Some people of the village, notably the poorer and elderly refused to leave as they didn’t want to leave all they owned behind. The proximity of settlements to an area of seismic activity and the growth of urbanisation are two more human factors that affect the impacts greatly. These factors can cause many fatalities, but the impacts can be decreased by using land use regulations. These include land use zoning and exclusion zones, where there are laws as to the type and size of buildings able to be built in that area. This prevents many fatalities unlike in the Gujarat Earthquake, where it was estimated that 800,000 buildings were seriously damaged. A
