Outline of Final Research Achievements

"Soteigai(Unforeseenable)" is an important word to describe the huge recent natural disaster such as Tohoku-Oki Earthquake. We developed some teaching tools for studying these unforeseeable events, because there is a big gap between professionals and public. Simple and easy-made seismometers were developed and operated a practical observation of local and foreign earthquake using our seismographs. At the same time, seismograms recorded by JMA were compiled as a classroom exercise. We regard the term "Soteigai" is originated with the power laws behavior of natural hazards. Therefore we developed some analog and computer models to demonstrate in a classroom how these power law behaviors are generated.　Also, we studied how psychological biases about "randomness" or "periodic" concepts affect students in their hazard images.
