Document Summary
Clear eye light circulation that demonstrates the centre. Hawaii characterized by volcanic activity (at the equator) Nature provides us with a lot of hazards and we have to control our vulnerability to these hazards. To ancient peoples, disasters were precipitated by the stars. Natural events that can occur include: earthquakes- occur on local and regional scales (a range of space of 10 km) Oods - local to regional hurricanes - regional (wind has a large impact) tsunamis - regional to global climate change - local, regional and global the larger the phenomenon the more energy involved. Hazard: potential threat to human kind and their welfare. Risk: probability of loss (death, injuries, damage, disruption of economic activity) as a result of a particular natural event. Vulnerability: potential loss, or degree of loss, from the event (0 = no damage, 1 = total loss) Larger amount of vulnerability = the more potential for disaster.
