  • 2. Hazards and responses: RISK? <ul><li>RISK </li></ul><ul><li>“ The exposure of people to a hazardous event” Why do people place themselves at risk from hazards? </li></ul><ul><li>Unpredictability </li></ul><ul><li>Lack of alternatives (economic, lack of land) </li></ul><ul><li>Changing dangers (vary spatially / time, e.g. coasts) </li></ul><ul><li>Optimistic outlook (accept them as part of life) </li></ul><ul><li>Costs vs Benefits (e.g. California) </li></ul>
  • 3. &nbsp;
  • 4. Vulnerability <ul><li>Vulnerability to hazards has 3 aspects: </li></ul><ul><li>Peoples preparedness </li></ul><ul><li>Resilience </li></ul><ul><li>Health (relating to social, economic and political factors) </li></ul><ul><li>Distinctions can be made between MEDC and LEDC </li></ul>
  • 5. <ul><li>We receive, filter and distort information as part of human perception. Past experience and values is important factor. </li></ul><ul><li>ACCEPTANCE </li></ul><ul><li>ADAPTION </li></ul><ul><li>DOMINATION </li></ul>Hazard Perception

  • 8. Hazard Response Prevent or modify the event? Prediction and warning.
  • 9. Careful Planning?
  • 10. <ul><li>Decision ….Modify the event, modify human vulnerability or modify loss? </li></ul><ul><li>Technological fix and environmental control (mainly with flooding, cloud seeding has had little success) </li></ul><ul><li>Hazard-resistant design – building design and engineered defences. </li></ul><ul><li>Change human attitude and behaviour towards hazards </li></ul>
  • 11. <ul><li>This will reduce the impact </li></ul><ul><li>Needs a good understanding of geophysical processes </li></ul><ul><li>What technology is available? (also MEDC/LEDC?) </li></ul><ul><li>Predictions will not stop event – but will provide warnings so they can prepare and evacuate </li></ul><ul><li>Insurance companies spend large amounts trying to predict. Why? </li></ul><ul><li>Community must have an understanding of procedures. </li></ul>Prediction and Warning
  • 12. <ul><li>Warning is a message that informs about risk. </li></ul><ul><li>Needs adequate monitoring and evaluation of data and dissemination via radio, TV, police. </li></ul><ul><li>Community must have an understanding of procedures. </li></ul>

Share the Losses? <ul><li>Aid </li></ul><ul><li>To what extent should this be given to countries who have failed to adequately prepare? </li></ul><ul><li>Insurance </li></ul><ul><li>A key strategy in MEDCs. (spread the cost) </li></ul><ul><li>Can encourage individuals to take preventative measures. </li></ul>

  • 15. &nbsp;
  • 16. &nbsp;
