What is a disaster?

As a record heatwave grips Western Canada and the West coast of the United States, local authorities are providing cooling centres and free cold drinks to senior citizens and people vulnerable to excessive heat.

People often mistakenly refer to a hazard as a disaster.

A hazard is a process, phenomenon or human activity that may cause death, injury or other health impacts, property damage, social and economic disruption, or environmental degradation. The above-mentioned heatwave is a prime example.
