"What are hazardous Environments and how can hazards be classified?"

Extracts from this document...

Introduction

"What are hazardous Environments and how can hazards be classified?" When you think about hazards, a number could be named, like volcanoes, hurricanes etc. And that you could tell that they exist all over the world. In fact, a hazard is only classed a hazard if it affects the interests of human life in any way. Be it more direct, for example a tsunami affecting the lives of human, or a hurricane, that leads to damage of property. One of the well-known hazardous environments is that surrounding an active volcano. These possess the power to terminate human life and also cause damage to property and other issues surrounding human existence, therefore it is classed as one of the major hazard areas on Earth. Volcanoes form on the edges of tectonic plates, which exist all over the globe. The following diagram shows the location of the major tectonic plates. Deep under the Earth's Crust, is where the Mantle is found; this is a body of solid rock. When the Mantle melts due to high pressures and temperatures it finds its way up to the surface through weaknesses in the Earth's Crust. A lot of gas build-up occurs as the molten Mantle rock (also known as Magma) ...read more.

The wave is carried for miles, and the further it travels to land, the greater and more powerful the wave. In the deep ocean, their length from wave crest to wave crest may be a hundred miles or more but with a wave height of only a few feet or less. They cannot be felt aboard ships nor can they be seen from the air in the open ocean. In deep water, the waves may reach speeds exceeding 500 miles per hour. Tsunamis are a threat to life and property to anyone living near the ocean. For example, in 1992 and 1993 over 2,000 people were killed by tsunamis occurring in Nicaragua, Indonesia and Japan. Property damage was nearly $1 billion. Large tsunamis have been known to rise over 100 feet, while tsunamis 10 to 20 feet high can be very destructive and cause many deaths and injuries. Tsunamis are not only caused by earthquakes, but also by a number of other things, like meteors and underwater landslides, all creating tsunamis. One example happened 65 million years ago, with the meteor that made the dinosaurs become extinct. The meteor that crashed into the Yucatan Peninsula of Mexico creating a tsunami that deposited sediment along the Gulf of Mexico and the United States. ...read more.

Conclusion

In an ideal world, this would make sense. Unfortunately, money is the important factor here. A huge number of disasters happen in LEDCs where the funding for aid, defence and rebuilding is not always available. Of course not every hazard happens on a set timing. Many have periods of centuries before a reoccurrence, whereas some only have years. It depends on the frequency of the hazard as well to see whether it is a high-risk or low-risk hazard to mankind. Giving examples, tornadoes in the central states of the US happen annually and it is obvious that they pose more threat than a massive volcanic eruption that happens every 100 years. We have time to re-build and learn about the flaws with a hazard that happens every 100 years, yet one that happens every year, money must be invested in order for man to survive in that area, and not be killed off by the reoccurring disaster. In conclusion there are a number of hazardous environments that affect daily lives of humans all over the world, be it as small as hay fever, to as big as a tsunami. The unfair distribution of money seems to determine which areas of the world are more "safe" from these hazards but, the question that is in my mind, is whether can we survive this never-ending battle against nature? ...read more.
