The Fukushima Disaster occurred in March 2011 when a massive earthquake and tsunami struck Japan, leading to the failure of the Fukushima Daiichi Nuclear Power Plant. The natural disaster caused cooling systems to fail, resulting in the release of radioactive materials into the environment. In response to the crisis, the Japanese government declared a nuclear emergency and evacuated residents within a 20-kilometer radius. The disaster raised global concerns about nuclear safety and prompted discussions about energy policies, leading some countries to reconsider their reliance on nuclear power.
