Despite all these frightening data, we must make it clear that despite all these earthquakes and tsunamis, Japan is a much safer country than our dear Brazil. So don't use Japan as something dangerous or scary. Many more people die in 1 year in Brazil because of violence and recklessness in traffic than in 20 years of earthquakes and tsunami in Japan.
