Lesson 3-How can we manage natural hazards?

Question 1

Domination

Answer 1

We can understand natural hazards through science

Question 2

How can we mitigate natural hazards?

Answer 2

• Scientific studies
• Population education
• Changes in engineering building practices
• Management and hazard response sharing

Question 3

The Hazard Management Cycle

Answer 3

1st Third-Modifying the Loss
2nd Third-Modifying the event
3rd Third-Modifying Human Vulnerability

Question 4

How is disaster management effected by economic wealth?

Answer 4

• The best management usually consists of strong structures that can withstand the force of an earthquake
  -e.g external steel frames costs lots of money to install
  -e.g houses in Pakistan have no cross-bracing

Question 5

What are strengths of the HMC?

Answer 5

• Can help areas prepare for a hazard by creating plans for each stage to mitigate the responses

Question 6

What are weaknesses of the HMC?

Answer 6

• Reductionist as its straightforward
  -stages dont occur in isolation as in reality they can overlap

Question 7

The Park Model

Answer 7

Question 8

Strengths of the Park Model

Answer 8

• Useful to compare hazards between countries (HIC’s and LIC’s)
• Useful to analyse responses and how/ when they happen

Question 9

Weaknesses of the Park Model

Answer 9

• Too general about impacts of hazards as magnitude, frequency etc effect responses
• Doesnt account for inequality in development, spatial variation
• Generalised as its not specific about the steps to recover
