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.
All these events are difficult for humans to adapt to. Human bodies have not gone through an evolutionary process where we can coupe with such disasters.
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.
