TYPES OF HAZARD

WORLD AT RISK

Slide2

What you should achieve this lesson

Know some key terms in relation to the topic

Understand how to classify different hazard types

Recognise the difference between a natural hazard and a disaster

Slide3

Key terms

With a partner I want you to try to come up with and write a definition of the following:

Natural Hazard

Disaster

Risk

Vulnerability

Hydro-meteorological hazard

Geophysical hazard

Slide4

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 people’s 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.

Slide5

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

Slide6

Natural hazard(Dregg’s 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

Slide7

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)

Slide8

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.

Slide9

Vulnerability

Vulnerability is the

degree

to which you are

susceptibl

e to physical or emotional injury or attack

Slide10

What is the connection?

GROUP 1ALL ARE HYDRO-METEROLOGICAL HAZARDS

Slide11

What is the connection?

GROUP 2ALL ARE GEOPHYSICAL HAZARDS

Slide12

What is the connection?

GROUP 3COULD FIT INTO EITHER

Slide13

Hydro-meteorological hazard

Discuss with your partner what you think this means

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 degradation

Slide14

HYDRO-meteorological hazards

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.

Slide15

Geophysical hazards

Discuss with your partner what you think this means

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

.

Slide16

Chronic hazards

Discuss with your partner what you think this means

Chronic Hazard

A hazard that is

long-term and persistent

Examples:

El Nino

Global Warming

Slide17

What do you think?

Are hazards really ‘natural’?

Slide18

homework

Create a mini case study on Hurricane Irene

Watch the news

Read the papers

Look online

Where and why

What impacts have there been (short and long term; local, national, international)

Cost

Were any precautionary measures in place
