A natural disaster is "the negative impact following an actual occurrence of natural hazard in the event that it significantly harms a community".
A natural disaster can cause loss of life or damage property, and typically leaves some economic damage in its wake.
The severity of the damage depends on the affected population's resilience and on the infrastructure available.

Examples of natural hazards include: avalanche, coastal flooding, cold wave, drought, earthquake, hail, heat wave, hurricane (tropical cyclone), ice storm, landslide, lightning, riverine flooding, strong wind, tornado, typhoon, tsunami, volcanic activity, wildfire, winter weather.
