A massive 9.0 magnitude earthquake struck northeastern Japan on March 11, 2011, triggering a devastating tsunami. The tsunami overwhelmed the Fukushima Daiichi Nuclear Power Plant, damaging its cooling systems and causing reactors to meltdown. Over 15,000 people died and thousands more were displaced from their homes. Radioactive contamination from the nuclear accident spread concerns about health effects, especially for children, though international organizations say short term exposure poses limited risk to adults outside the immediate area. Ongoing monitoring of food and sea pollution is needed, as the full consequences are still unknown from such a large disaster.
