used to protect mainland coastal populations from cyclone effects may not be
appropriate or effective in island environments. If no inland infrastructure
exists that offers refuge from cyclone effects, procedures used in mainland
events (such as evacuation) are not viable options for the local populace.
Moreover, cyclone effects that are of little or no concern to mainland residents
may pose significant hazards in island environments. In contrast to mainland
tropical cyclone hazard scenarios which have been extensively studied and where
mature emergency management measures are in place, island hazard scenarios have
received little attention.
Adequate data exist to quantitatively depict
some of the various geophysical processes occurring during cyclone landfall in
islands (e.g., spectral wave transformation, coastal surge) such that models of
these processes have been developed. However, data depicting other processes
(e.g., wave-induced ponding, wind-forced wave uprush) are inadequate or do not
exist, consequently the physics of these processes are poorly understood and
adequate models are not available. Data of adequate quantity and quality
depicting the physics of these processes are required to develop these models.
