The risk assessment model has been considered lately as one of the most efficient approaches having the ability of quantifying probabilities or a chain of probabilities concerning natural hazards. Risk planning schemes and tsunami mitigation measures were introduced by the most technologically advanced countries that have been effected by earlier tsunamis. These nations have the required technologies and resources for applying advanced techniques for achieving the required tsunami mitigation plans. The authors, in a previous paper, invented a sustainable tsunami mitigation tool utilizing the risk assessment model; the tool was named 'Strategic Tsunami Risk Assessment and Planning Model' (STRAPM). The novelty of the tool was mainly based on the ability of having an efficient tsunami risk assessment mitigation planning tool that could be applied proficiently within the context and limitation of developing nations. The tool was designed to provide coastal communities, of developing countries, with an applicable proactive tool that would allow these communities to define tsunami risk zones and buildings; thus having the ability to initiate the appropriate mitigation planning and evacuation plans. Applying the STRAPM has proved the tool’s efficiency; however, a major deficiency has been noticed. Thus the authors aim, through this paper, to present a required refinement and to practically reexamine the efficiency of the STRAPM.
