Hurricanes are destructive storms with strong winds, intense storm surges,
and heavy rainfall. The resulting impact from a hurricane can include structural damage
to buildings and infrastructure, flooding, and ultimately loss of human life. This paper
seeks to identify the impact of Hurricane Ivan on the affected population of Grenada,
one of the Caribbean islands. Hurricane Ivan made landfall on 7th September 2004 and
resulted in 80% of the population being adversely affected. The methods that were used
to model these impacts involved performing hazard and risk assessments using GIS and
remote sensing techniques. Spatial analyses were used to create a hazard and a risk map.
Hazards were identified initially as those caused by storm surges, severe winds speeds,
and flooding events related to Hurricane Ivan. These estimated hazards were then used
to create a risk map. An innovative approach was adopted, including the use of
hillshading to assess the damage caused by high wind speeds. This paper explains in
detail the methodology used and the results produced.
