Topic Area 9
Modify Vulnerability
Prediction allows evacuation to save lives but not possible for earthquakes
Costs
Indian Ocean tsunami warning system = $200 million
Education
Japan Disaster Day
Hard in isolated areas
Cry wolf syndrome
Prediction + warning
Possible for volcanos
Does not prevent property damage
Modify Event
Aseismic buildings
Tsunami walls
Ugly
Overtopped
Landuse zoning
Low cost
Remove people from risk
Plant mangroves
Sustainable
Lava diversions
Spray with water, but only for low VEI
Overall, costly
Zoning prevents economic development on valuable land
Modify Loss
Long term aid for better reconstruction methods
Insurance
People recover economically
Not everyone can afford
Costly
Does not save lives
Emergency relief
Decrease death from disease = shelter
But difficult in isolated areas e.g. Kashmir 2005
Adaptation
Modify vulnerability
Modify the loss
Mitigation
Modify the event
