Natural Hazard/disaster - A natural hazard is when there is no potential threat to people and infastructure whereas a natural disaster has the potential to kill many people and destroy infastructure.

Human/physical factors that have made the Philippines a disaster hotspot:

  • Destructive plate boundary leading to earthquakes, volcanic eruptions etc.
  • Archipelago (islands) - much of the country gets affected when flooding occurs as so much of it is exposed to coastal regions
  • LEDC- cannot afford management strategies such as flood walls to prevent a disaster having a large impact
  • Many natural disasters occur in the Philippines such as typhoon Haiyan, which inflict a lot of damage on the Philippines that cannot be repaired up to a standard that would protect it from another hazard due to the poor economy, therefore it would be very easy to damage again

Main cause of the global sea level rise = thermal expansion

Physical geography that causes some coastal regions to be more at risk from rising sea levels than other regions:

  • Some coastal regions are very flat and low-lying such as Maldives.
  • There is highest erosion at coastal areas which puts people living on the coast at risk as their homes may be destroyed by the rising sea levels increasing pace of erosion and causing subsiding of land.

Human geography of areas e.g Bangladesh or the Maldives that makes them vulnerable to sea level rise:

  • Both LEDC's which makes them vulnerable as they may not be able to afford defences such as flood barriers that would help to prevent flooding from sea-level rise.
  • There is dense population in coastal areas…
