NATURAL HAZARDS

Question 1

What is a natural hazard?

Answer 1

a natural process which causes deaths, injury or disruption to humans

Question 2

What are the two types of natural hazards?

Answer 2

• geological = caused by the Earth and the tectonic plate movement
• meteorological = all to do with the weather and atmospheric condition

Question 3

What is a hazard risk?

Answer 3

the chance or likelihood of an event happening due to a natural hazard

Question 4

Name the three factors affecting the risk?

Answer 4

• urbanisation (population density)
• ability to cope
• nature of natural hazards

Question 5

Explain how does urbanisation affect the risk AND an example?

Answer 5

more people living in an area = more people are impacted by a NH(natural hazard)

EXAMPLE: the city Naples , in Italy is at the base of a volcano = that there are more vulnerable to volcanic eruptions

Question 6

Explain how does the ability to cope affect the risk AND an example?

Answer 6

different populations of people deal with the risk of NH/ND differently due to abilities

EXAMPLE: HIC’s are better coping with floods = can afford to build flood defenses and evacuate people

Question 7

Explain how does the nature of natural hazards affect the risk AND an example?

Answer 7

type = risk from some hazards are greater than others

EXAMPLE: tropical storms can be predicted and monitored = people have time to evacuate

frequency = some NH that occur more often may have higher risk

magnitude = more serve NH mostly have greatest effects

EXAMPLE: 9.0 magnitude earthquake in Japan (2011) killed 15,000 BUT 6.3 magnitude earthquake in Italy (2009) killed 300
