1.3 Extreme Natural Events becoming Natural Hazards
The only time we really need to worry about extreme natural events is when they threaten human activities. As soon as ENEs threaten humans and human activities then they become natural hazards.

Eg. A volcanic eruption on an uninhabitated is an ENE whereas a natural hazard is when Mt Ruapehu erupts and threatens tourist operations and local townships.
