Natural hazard A natural hazard is a naturally occurring process or event which affects people, e.g. causing loss of life or injury, economic damage, disruption to peoples lives or environmental degradation.A natural hazard is a naturally occurring process or event which affects people, e.g. causing loss of life or injury, economic damage, disruption to peoples lives or environmental degradation. Without people it is just a natural event not a hazard, it needs the interaction of people to make it a hazard. Without people it is just a natural event not a hazard, it needs the interaction of people to make it a hazard.

Slide 5

Natural hazard Hazardous geophysical event e.g. flood or earthquake Vulnerable population: susceptible to human and economic loss NO NATURAL HAZARD No interaction of human and physical systems

Slide 6

Natural hazard (Dreggs model) Hazardous geophysical event e.g. flood or earthquake Vulnerable population: susceptible to human and economic loss NATURAL HAZARD Interaction of human and physical systems DISASTER

Slide 7

Disaster The realisation of a hazard, although there is no universally agreed definition of the scale on which loss has to occur to qualify as a disaster.The realisation of a hazard, although there is no universally agreed definition of the scale on which loss has to occur to qualify as a disaster. (Smith 1996)

Slide 8

Risk Risk is the exposure of people to a hazardous event which may present a potential threat to people or their possessions, including buildings and structures.Risk is the exposure of people to a hazardous event which may present a potential threat to people or their possessions, including buildings and structures.

Slide 9

Vulnerability Vulnerability is the degree to which you are susceptibl e to physical or emotional injury or attackVulnerability is the degree to which you are susceptibl e to physical or emotional injury or attack

Slide 10

What is the connection? GROUP 1 ALL ARE HYDRO-METEROLOGICAL HAZARDS

Slide 11

What is the connection? GROUP 2 ALL ARE GEOPHYSICAL HAZARDS

Slide 12

What is the connection? GROUP 3 COULD FIT INTO EITHER

Slide 13

Hydro-meteorological hazard Discuss with your partner what you think this meansDiscuss with your partner what you think this means Hydro-meteorological Hazard Hydro-meteorological Hazard Natural processes or phenomena of atmospheric, hydrological or oceanographic nature, which may cause the loss of life or injury, property damage, social and economic disruption or environmental degradationNatural processes or phenomena of atmospheric, hydrological or oceanographic nature, which may cause the loss of life or injury, property damage, social and economic disruption or environmental degradation

Slide 14

HYDRO-meteorological hazards Examples:Examples: Cyclones, droughts, floods, storm surges, thunder/hailstorms, rain and wind storms, blizzards and other severe storms; desertification, wildland fires, temperature extremes, sand or dust storms; permafrost and snow or ice avalanches. Hydrometeorological hazards can be single, sequential or combined in their origin and effects.

Slide 15

Geophysical hazards Discuss with your partner what you think this meansDiscuss with your partner what you think this means Geophysical Hazard Geophysical Hazard Natural hazards where the principal causal agent is geological, geomorphological (e.g. landslides, tsunamis, volcanoes and earthquakes). They do not include biological hazards.Natural hazards where the principal causal agent is geological, geomorphological (e.g. landslides, tsunamis, volcanoes and earthquakes). They do not include biological hazards.

Slide 16

Chronic hazards Discuss with your partner what you think this meansDiscuss with your partner what you think this means Chronic Hazard Chronic Hazard A hazard that is long-term and persistentA hazard that is long-term and persistent Examples:Examples: El NinoEl Nino Global WarmingGlobal Warming

Slide 17

What do you think? Are hazards really natural?
