  12. Fukushima

  13. The Fukushima nuclear facilities were damaged in a magnitude 9.0 earthquake on March 11 (Japan time), centered offshore of the Sendai region, which contains the capital Tokyo. • Plant designed for magnitude 8.2 earthquake. An 9.0 magnitude quake is 8 times greater in magnitude. Serious secondary effects followed including a significant tsunami, significant aftershocks and a major fire at a fossil fuel installation.
