Japan is a seismically active region. In March 2011, a 9.0-magnitude offshore earthquake triggered a 46-foot tsunami that hit Japan's Fukushima nuclear power, leading to the leakage of radioactive materials and the shutdown of the plant. The accident is considered to be the world's worst nuclear disaster since Chernobyl.
