A natural calamity is a major adverse event resulting from natural processes of, or effecting, the Earth; examples include floods, severe weather, volcanic eruptions, earthquakes, and other geologic processes. A natural calamity can cause loss of life or property damage, and typically leaves some economic damage in its wake, the severity of which depends on the affected population's resilience, or ability to recover.
A natural calamity are the side effects or the after effects of natural issues or hazards like flood, volcanic erosion, land slide or earthquake which will lead to the human, monetary and environmental losses. The eventual loss generally depends on the probability of the population which is affected by the natural calamities. The belief is focused in the forming of natural calamity, which happens when the disasters meet the probability of the people affected by these disasters or natural calamities.
Hence, the natural calamity will not eventually lead to a natural hazard in the areas where there is no vulnerability or probability like, for example, an earthquake with a strong wave range will not affect the area which is less populated or uninhabited locations. The word natural has eventually become controversial because of the fact that these calamities or events may generally not so dangerous or hazardous until and unless there is any human being involved or effected by it. A strong and simple example which will clearly define and differentiate between a natural hazard or danger and a natural disaster is that in 1906 when there was a strong wave range earthquake in San Francisco. Natural calamities would be the phenomenon which can’t always be prevented, but we can get precautions. Natural Calamities such as: earthquakes, Tsunamis, floods, tornados, and volcanic erosions, which cause disorder within our everyday lives. At the moment, with the support in Science and expertise, we will be capable to offset these natural calamities
