THE BASIC STUDY ON TSUNAMI DISASTER MITIGATION MEASURES BASED ON SURVIVAL PROBABILITY

Abstract

 For keeping lives of the people against low frequency-huge tsunami, it is necessary for the disaster reduction to consider the efficiency improvement. The acceptance risk for people's lives is generally said to be borderline 10-5 (/year). This study challenged to develop the method for implementing policies to protect lives on the target level against tsunami disasters. the numerical simulation on probabilistic tsunami for getting inundation depth and that arrival time are carried out to synchronize evacuation simulation In order to reach the target survival probability, this study reevaluated with adding countermeasure.
