Natural Hazards can be described as dangerous occurrences that are a threat to human survival. These can include unforeseen sudden events such as earthquakes, volcanoes, Tsunamis and tornadoes. This can also include some slow-moving disasters e.g. droughts, climate change and even diseases.

In modern countries, some precautions have been developed e.g. dams to store water in times of drought or earth-quake proof buildings seen in Japan.
Generally, humans in poorer countries are more susceptible to natural hazards due to poor infrastructure.
