10. Fukushima
The worst nuclear disaster in Japan occurred not so long ago, on March 10, 2011. The Fukushima plant was struck by a by a tsunami which was a consequence of an earthquake. The tsunami damaged the power generators, and although they were successfully shut down, a series of explosions took place which led to the release of huge amounts of radioactive material. It took over a month to get things under control and people were evacuated from the area while some of them were injured, too.
