  • The size of the earthquake was the fifth biggest in history of the world;
  • The duration of the strong earthquake shake was up to 5 minutes.

The Fukushima nuclear disaster

  • The size of the waves that hit the Fukushima Plant were 15 meters. 
  • Number of complete nuclear leaks at the nuclear plant were 3;
  • Communities were instructed to maintain a distance of around 25 km from the disaster site;

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 beloved Brazil. So don't have to 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 tsunamis in Japan.
