The Fukushima Daiichi nuclear disaster occurred on March 11, 2011, following a massive earthquake and tsunami that struck Japan. The natural disaster disabled the power supply and cooling systems of three reactors at the Fukushima Daiichi Nuclear Power Plant, leading to core meltdowns and 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 many countries to reevaluate their nuclear energy policies and emergency preparedness measures.
