Risk reading Warn (2008) Relationship between severity of a hazard, its probability and degree of risk



3. Use a diagram to help show the 'risk assessment process'.
== 4. What is the relationship between a hazard's severity, its probability and the degree of risk? ==

5. Explain the risk-vulnerability relationship.
== 6. Identify factors and examples where risk awareness can be increased and decreased. Relate these to your existing case study examples. == == 7. Using specific examples and case studies, give examples of when and why countries have underestimated the risks posed by hazards. ==

= Using named examples, explain how the relationship between risk and vulnerability can produce varying hazard-event outcomes? (10 marks) =

Analyse each of your case studies for their risk and probability by completing the matrix below. Hurricane Katrina for example would have a low probability of the event happening but a high level of risk.
