2 Definition of a natural disaster A disaster that is caused by naturally-occurring hazards 2

3 Classes of natural disasters Hydro- meteorological Floods Storm surges Windstorms Wildfires Heat waves Dust storms Snowstorms Geological Earthquakes Tsunamis Volcanic Landslides Avalanches 3 Biological Epidemics Pandemics

4 Hazard-based classification of natural disasters 4 NATURALNATURAL GeologicalHydro-meteorological SeismicVolcanic High precipitation Low precipitation Earth- quake TsunamiVolcanic eruption Land- slide Tropical Cyclone FloodDroughtWildfire Keim 2010

5 Pacific islanders carry the highest disaster burden in the world 5

6 Pacific islanders have the 2 nd highest mortality rate in the world 6

7 Pacific islands have the 2 nd highest per capita losses in the world 7

8 The incidence of natural disasters is increasing worldwide ( ) 8

9 Top 4 causes of death due to disasters in the Pacific 9 Tsunamis Cyclones Floods Landslides

10 Most disaster deaths occur BEFORE emergency response Hazard Cause of death Tsunami Severe trauma and drowning Cyclones Drowning Floods Drowning Landslides Severe trauma 10

11 Vulnerability to natural disasters 95% of natural disaster deaths occur among 66% of the poorest countries 11

12 Public health consequences of natural disasters Death Injuries Loss of clean water Loss of shelter Loss of personal household goods Major population movements Loss of sanitation Loss of routine hygiene Disruption of solid waste management Public concern for safety Increased pests & vectors Damage to health care system Worsening of chronic illnesses Loss of electricity Toxic/ hazardous exposure Loss of food supply 12

14 So, how do we reduce health risk? Reduce exposures Identify the hazard Monitor the hazard Provide early warning Evacuate people at risk Reduce vulnerability Promote health and education Strengthen public health and healthcare Protect key resources Livelihoods, shelter, food, water, sanitation 14
