Using Computer Simulation for Effective Tsunami Risk Communication
With the lessons learned in the Great East Japan Earthquake in 2011, the Japanese Cabinet Office recalculated some existing disaster assumptions. As a result, the Nankai Trough has been assessed as being at risk for a huge earthquake and tsunami. Evacuation plans have been reconsidered in each Japanese administrative sector to be more practical for saving resident’s lives. However, two problems arise concerning tsunami evacuation planning. First, such a disaster creates an infinitely complex situation because of the many factors involved. Second, it is difficult to verify whether any plans will actually work. Therefore, we cannot fully demonstrate the feasibility of these plans. To cope with these difficulties, computer simulation is well known as an effective way to verify plans. In this chapter, an effective process to propose feasible options on tsunami evacuation for residents by combining two approaches will be discussed. The first is a computer simulation that calculates a large variety of evacuation situations to find their most effective behaviors. The second proposes practical methods for testing the behaviors proposed by the results of simulation. The process appears to be effective in developing improved evacuation plans for residents.
