Well it can be put like this ~ A natural disaster is the effect of a natural hazard (e.g. flood, tornado, volcanic eruption, earthquake, or landslide) that affects the environment, and leads to financial, environmental and/or human losses. The resulting loss depends on the capacity of the population to support or resist the disaster, and 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.
The following is a list of the most notable natural disasters:
* Contractible diseases
* Floods and landslides
* Limnic eruptions
* Storms (non-cyclone)
* Volcanic eruptions
* Wildfires and bushfires
The United Kingdom based charity Oxfam publicly stated that the number of people hit by climate-related disasters is expected to rise by about 50%, to reach 375 million a year by 2015.
