Abstract

Evacuation from natural disasters is a complicated set of activities. An evacuation cycle is introduced in order to analyze the complexity by dissecting it into an elemental component and the cycle is tested for hurricanes. Current states of activity components of interest are discussed descriptively, which gives us an insight to see a general trend of hurricane evacuation in the United States. The feasibility of an evacuation is judged based on a comparison between the time available for evacuation and the time necessary for evacuation. The time available for evacuation mainly varies with the time evacuees spend for their judgment. The results indicate that hurricane evacuation could fail without appropriate consideration on the credibility and clarity of warning signs and on regional property such as demography. The future applicability to more rapid forms of disasters as sediment-related disasters is discussed.
