Sudden onsetA sudden event occurs with little or no warning and has immediate adverse effects on the human population, activities, economic system and natural environment. Examples of this type of disaster would be earthquakes and hurricanes.
Slow onsetThis refers to a situation in which the ability of people to sustain their ‘usual’ activities slowly declines to a point where survival is jeopardised. Such situations are typically brought on by environmental, social, economic and political changes.The task below will give you the opportunity to define the range of disasters into sudden onset and slow onset.
