What Kind of Damage does it do to coral reefs?

  • erosion:
    • destruction and removal of coral
    • removal of surface sand and soil
    • storm ridges
  • biodiversity

Recovery

  • time needed to return to original state
  • greater damage can take anywhere between 5 to 40 years to recover

History of Cyclones

  • Impacts on the Great Barrier Reef
    • Case study: Cyclone Ingrid
      • intensity
      • damages
    • Case study: Cyclone Yasi
