Natural disaster is the occurrence of natural processes of the earth system. As we know the earth system is comprised by the Lithosphere, Hydrosphere, Biosphere, and Atmosphere. In each of these spheres, there are natural processes. These natural processes are the normal cycle for the spheres to generate the equilibrium of the earth system. Examples of these natural processes are Volcanic eruption, Tsunami, Earthquake, Hurricanes, Floods and so on. When these natural processes affects human and causes lost of lives and properties, then is known as NATURAL DISASTER.

Wikipedia: Definition of Natural Disaster

A **natural disaster** is the effect of a [|natural hazard] (e.g. [|flood],(tornado) [|volcano 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.[|[1]] This understanding is concentrated in the formulation: "disasters occur when hazards meet [|vulnerability]."[|[2]] 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.[|[3]]
