Abstract

This study collected and classified a wide range of natural infrastructures and local infrastructures expecting reduction effect of tsunami disaster, in addition to clarifying the relation between sort of infrastructures and effect of duration.
Natural infrastructures and local infrastructures are divided into 40 classes, tangible reduction effect of tsunami disaster is 8 classes and intangible reduction effect of tsunami disaster is 32 classes. Infrastructures unrelated tsunami disaster directly are 20 classes and these are important to be recognized.
Tangible infrastructures closely connected to everyday life tend to inherit effect comparison with intangible infrastructures.
