A Natural Phenomenon is anything that occurs on its own in nature without any human intervention. For example, the weather of a place, fog, storms, winds, tides, volcanic eruptions and cyclones all can be categorized as natural phenomena: phenomenon - any state or process known through the senses rather than by intuition or reasoning. Phenomena are born, but the disasters are produced by human action in his environment. The presence of human settlements in the area creates the possibility of a disaster.
