Natural disasters are tragedies resulting from otherwise extreme natural occurrences and are hardly ever human induced. Some of these natural disasters have been discovered to be amplified by human interference. An example is apparent in cases of floods and tsunamis that are as a result of shifts in the planes of the continental shelf of oceans and tremors. Global warming has been an issue of global debate and concern for over two decades now. One of the attendant consequences of global warming has been the rapid meltdown of ice in the arctic and Polar Regions of the earth. This has increased the volume of water in the ocean and an otherwise slight tremor in the ocean belt could prove devastating because of the increased volume of water.

In the case of floods under similar circumstances, rivers and oceans will naturally overflow their banks and because there will also be more water in the atmosphere; there are usually chances of tropical storms and torrential rainfall that are also veritable agents of flooding. Flooding under normal weather conditions have also been traced to human factors such as deforestation which has also been known to accelerate the pace at which the deserts are eating into normal habitations of humans. Another human induced natural disaster from these quarters is sandstorms. Examples of natural disasters are volcanic eruptions, tsunamis, hurricanes, tropical storms, tornadoes, flooding and earthquakes. In whatever means they come, natural disasters remain unavoidable by humans and are the biggest sources of destruction on the earth planet often leaving from several hundreds to tens of thousand deaths with several more missing or displaced. Damages are usually valued in millions and billions of pounds.
