WHAT IS DISASTER?
A disaster is the tragedy of a natural or human-made hazard (a hazard is a situation which poses a level of threat to life, health, property, or environment) that negatively affects society or environment. A disaster can be defined as any tragic event with great loss stemming from events such as earthquakes, floods, catastrophic accidents, fires, or explosions.
In contemporary academia, disasters are seen as the consequence of inappropriately managed risk. These risks are the product of hazards and vulnerability. Hazards that strike in areas with low vulnerability are not considered a disaster, as is the case in uninhabited regions.
The word derives from Middle French désastre and that from Old Italian disastro, which in turn comes from the Greek pejorative prefix δυσ-, (dus-) "bad" + ἀστήρ (aster), "star". The root of the word disaster ("bad star" in Greek) comes from an astrological theme in which ...view middle of the document...
The resulting loss depends on the capacity of the population to support or resist the disaster: their resilience. This understanding is concentrated in the formulation: "disasters occur when hazards meet vulnerability". A natural hazard will hence never result in a natural disaster in areas without vulnerability, e.g., strong earthquakes in uninhabited areas. The term natural has consequently been disputed because the events simply are not hazards or disasters without human involvement.
Disasters caused by human action, negligence, error, or involving the failure of a system are called man-made disasters. Man-made disasters are in turn categorized as technological or sociological. Technological disasters are the results of failure of technology, such as engineering failures, transport disasters, or environmental disasters. Sociological disasters have a strong human motive, such as criminal acts, stampedes, riots and war. Man-made disasters are events which, either intentionally or by accident cause severe threats to public health and well-being. Because their occurrence is unpredictable, man-made disasters pose an especially challenging threat that must be dealt with through vigilance, and proper preparedness and response. Information on the major sources of man-made disasters is provided here to help educate the public on their cause and effects as they relate to emergency planning. A man-made hazard is a threat having an element of human intent, negligence, or error, or involving a failure of a man-made system. Man-made disasters are disasters resulting from the same factors.
TYPES OF MAN MADE DISASTERS
1.Deforestation and land slides.
2.Depletion of ozone layer and global warming -- causing erratic monsoons and hurricanes.
3.Over use of chemicals and fertilisers
4.Toxication of rivers by industrial waste
5.Dumping radio active material waste in sea.
6.Unsafe handling of nuclear reactors.
7 Improper handling of biological experimatations and waste.
8.Over mining of natural resources
10.Air pollution due to vehicles and CFC's
