- Global Hazards
- Is the world becoming more hazardous?
- Due to the media disasters like Hurricane Katrina or the 2004 Boxing Day Tsunami stay in our minds for years
- Floods and windstorms are becoming more frequent (accounting for 75% of natural disasters) due to warming of the sea and more convection currents in the atmosphere
- On the whole deaths are becoming less frequent but financial damage has sky-rocketed
- Effects of natural disasters on people
- The number of people who are effected each year has increased
- Due to the population rising to 7 billion in 2011 people now inhabit once uninhibited areas
- More people live in marginal areas
- Coastal cities in which harbour side or beach side houses and flats are more exposed to hurricanes
- Housing developments on river flood plains which, by their nature, are more likely to flood
- Who suffers the most from disasters?
- This is mostly relative
- Because MEDC's have high value infrastructures and builds financial damages is much higher in these areas
- In LEDC's they do live in marginal areas due to rapid urbanisation but their houses and infrastructure is cheaper meaning less financial damage but because its weaker more death
- On the whole these areas are more at risk too because most LEDCs are near plate boundaries such as the Philippines or hotspots (Hawaii)
- This is mostly relative
- Investigating the world's worst?
- 2005 Earthquake in Pakistan in October there were 70,000 deaths
- 2005 Hurricane Katrina killed 1300 people and caused $81 billion in damages
- Why are floods and windstorms increasing?
- Increased warming of the earth causes warm air to rise creating convection cells which form hurricanes
- Increasing temperatures increase evapouration evapouration which leasds to more percipitation and therefore more flooding
- The tsunami horror
- 2004 Boxing Day Earthquake it was was a rare one - it only occurs 100 years or so
- 9 on the Richter scale it was 100 times stronger than the Kobe earthquake in 1995
- 275,00 people died
- 9$.9 billion in damages
- 141,000 homes were destroyed
- 2004 Boxing Day Earthquake it was was a rare one - it only occurs 100 years or so
- Is the world becoming more hazardous?
