Differential Impacts & Tectonic Hazard Patterns Flashcards
1
Q
Global disaster trends:
A
- Focuses on the patterns, causes impacts and responses to natural hazards & disasters across the world
- ## The trends show how earthquakes, floods, hurricanes & droughts have evolved overtime & impact regions of the world
2
Q
Key trends in Global Disasters:
A
- Number of disasters recorded has increased
Due to: - Increased population, more people are likely to be impacted by a hazardous event
- Increased population desnsity in Urban and Coastal areas increases the vulnerable population
- Increased monitoring and reporting means more hazard events are recorded
3
Q
Tectonic Disaster trends:
A
- Natural hazards are resulting from the movement of tectonic plates
- Understanding the trends in tectonic disasters involves:
1. Analysing Frequency
2. Distribution
3. Impacts
4
Q
Key trends in Tectonic Disasters:
A
- Has fluctuated but remained fairly steady
- Increase in number of earthquakes due to:
- Greater urbanisation - higher population densities & increased building density
- Population growth means more people are living in earthquake-prone regions
5
Q
Number of deaths:
A
Deaths from all hazards overtime has decreased this is because of:
- Improved building construction
- Increased monitoring
- Greater preparation & planning
- Education - earthquake drills
- Improved warning systems
- Increased development
6
Q
What is a mega-disaster?
A
Is an event that causes wide-spread damage on a global or large-scale
7
Q
Economic cost trends:
A
- The cost of economic disasters has increased overtime
- As countries develop the cost of repairing infrastructure/rebuilding increases
- Increased wealth means people have more possessions and property to be damaged and destroyed
- Infrastructure is more sophisticated and expensive to replace
- The economic disasters is affected by whether the country if developing (LIC) or developed (HIC)
- The economic cost in the US$ tends to be higher in developed countries
