With reference to 1 or more detailed case studies explain why most natural hazards are not entirely natural. A natural hazard is a natural event that presents a risk to people, plants, property or animals. If people or animals are injured or property and plants damaged it becomes a natural disaster, if not it remains a natural event. A natural hazard is when extreme natural events or processes occur in an area of human settlement and cause loss of life and damage to existing constructed resources and infrastructures. A hazard only occurs when it becomes online to create a potential disaster. In this essay I will be using several different case studies to show how sometimes natural hazards are caused by humans or maybe their actions are causing and making these hazards not that natural. Often people put themselves in danger for example living at the bottom of mount Popocatepetl in Mexico city just for the good fertile soil regardless of the risk of the volcano maybe erupting at any moment. People do have to live somewhere but maybe if they avoided living or building on areas which shouldn't be built on such as floodplain in Gloucester, UK. To also help me answer this question I will be looking at the cause of avalanches,which are the rapid descent of a large mass of rock, ice and snow down a steep mountain slope. ...read more.


In February 1999 an avalanche occurred in Chamonix, France, 10 people were killed, 11 rescued unhurt, five with minor injuries, one seriously injured, two believed to be missing. Not only did this avalanche effect people in Chamonix but also affected surrounding ski resorts, destroying chalets and buildings. Avalanches would not occur if skiers were not on the slopes triggering them off in the first place this is why I feel avalanches are not natural, yes they would occur if no humans were present but their likelihood is much greater with the influence of humans. People do have to live somewhere and most people have little choice about where they live. Over the last 10 years more than 2 million new properties have been built, urbanising a massive area of land, and has resulted in water running off into rivers at a much faster rate, causing higher flood peaks and greater risk. This is made worse where developments have taken place on floodplains. Agricultural intensification has also improved drainage, accentuated by over-grazing and soil compaction which reduces the ability of land to soak up water. In the last 25 years we,ve also drained and filled in 60% of our floodplain water meadows which once acted as a natural safety valve, holding back floodwaters and reducing flooding risk downstream. ...read more.


Humans are the main cause of global warming, in the USA, approximately 6.6 tons of greenhouse gases are emitted per person every year. And emissions per person have increased about 3.4% between 1990 and 1997. Most of these emissions, about 82%, are from burning fossil fuels to generate electricity and power our cars. The remaining emissions are from methane from wastes in our landfills, raising livestock, natural gas pipelines, and coal, as well as from industrial chemicals and other sources. Humans can affect the emissions of about 4,800 pounds of carbon equivalent, or nearly 32% of the total emissions per person, by the choices you make in three areas of your life. These areas are the electricity we use in our homes, the waste we produce, and personal transportation. The other 68% of emissions are affected more by the types of industries in the U.S., the types of offices we use, how our food is grown, and other factors. Rising global temperatures are expected to raise sea level, and change precipitation and other local climate conditions. Changing regional climate could alter forests, crop yields, and water supplies. It could also affect human health, animals, and many types of ecosystems. As you can see the whole cause of global warming is based on human causes, thus meaning all the consequences of it and affects are not natural but are man caused making the hazards (flooding) not natural. ...read more.
