Abstract
Risk is usually defined to be the product of (hazard) × (vulnerability), or alternately, (hazard) × (exposure). Ameliorating risk can be accomplished either by reducing the hazard, or reducing the exposure to the hazard. For natural hazards, it is usually not possible to prevent the hazard. Earthquakes and hurricanes are examples, although events such as human-induced earthquakes in areas of ground water injection may be exceptions. One strategy is to simply move away from hazardous areas, thereby reducing the exposure to the hazard. Another method is to alter and strengthen physical structures and social processes so that they are less susceptible to disruption and destruction.
