Natural disasters are naturally occurring events, or extreme forces of nature, that cause injury, death of people, local communities, property, parts of society and even entire civilisations.
Here are a few common ones:
- Bushfires - aka wildfires
- Cyclones and hurricanes (tropical cyclones)
- Volcanic eruptions
The scale of natural disasters can vary from affecting only a few people to entire countries or regions and sometimes a global scale.
Sometimes the topic of natural disasters is called 'Natural Hazards', to highlight that nature can be hazardous.
Some less common ones (depending on location and climate) might include:
- Rock slides
- Snow or ice storms (Blizzards)
- Lightning strikes
Rare extra terrestrial (originating away from earth) origins:
- Asteroid and meteoroid impacts, technically called impact events
- Solar flares
- Cosmic gamma ray bursts
Outbreaks of disease may also be considered natural sometimes. For example some wild animals may carry diseases, such as bacteria, viruses or parasites that could infect a population.
Wild animal attacks could also be considered a type of natural disaster but on a more smaller personal scale. Examples might include:
- stampede of elephants or
- shark attacks on people
- Pirhana attacks
Though these usually are more opportunistic or reflexes.
Essentially any extreme form of nature could be considered a natural disaster. There are other kinds of disasters such as:
- social disasters, such as wars,
- engineering disasters or
- technological related disasters.
