Hazard perception and response'

1
Hazard perception and response.

• Perception is what we believe or understand about
  something.
• At an individual level our perception of risk
  often fails to match the reality because we
  receive filter and distort information.
• Therefore responses to hazard risks at an
  individual, community and national level may be
  significantly influenced by perception.

Adaptation hazards influenced by human natural
systems. Magnitude and frequency may be
estimated-based on experience research.
