Rational Perception of Risks
- When a hazard appears infrequently in an area and with low intensity, people will choose to absorb losses.
- When a hazard exceeds the awareness threshold, people will take notice of it. However, they will still accept the losses.
- When the frequency and magnitude of the hazard reaches the action threshold, people will take measures to minimise the losses.
- When the hazard exceeds the intolerance threshold, people will move away from the area.
- Some believe hazards cannot occur in the same location twice, i.e. 'Lightning does not strike the same place twice.'
- Some believe that the occurrence of hazard is controlled by a deity, and it is thus meaningless to attempt to evade it.
- Some may forget the possibility of a hazard after a long time, e.g. dormant volcanoes.
- Some may believe the government provides sufficient production, and it is thus unnecessary to move out of the area.
