Mitigating the Risk from Coastal Hazards: Strategies and Concepts for Recovery from the December 26, 2004 Tsunami

摘要

This report presents strategies, concepts and options for the recovery and redevelopment of areas damaged by the December 26, 2004 tsunami. Particular emphasis is placed on the use of scientifically based hazard mitigation measures for siting and construction in conjunction with flexible implementation strategies in the land use and construction process. It is believed that the technically based standards will protect the public to a greater degree from future flooding and wave events, while the flexible strategies will ease and expedite implementation and overall recovery. From a technical standpoint, methods for dividing the tsunami inundation zone into subzones are introduced. Within the subzones, appropriate multi-hazard mitigation measures are presented. Recurrence interval considerations are discussed, as well as strategies to adjust the construction and siting standards based on the interval. In chapters 3 to 5, concepts and strategies to assist implementation of the technically based standards are presented to assist the short-term and long-term recovery of tsunami stricken areas.
