Tōhoku Earthquake Triggers Fukushima Disaster
A magnitude 9.0 earthquake struck off the northeastern coast of Honshu, Japan, at 2:46 p.m. local time. The quake generated a massive tsunami that inundated coastal areas, including the Fukushima Daiichi Nuclear Power Plant. Reactor cooling systems failed, leading to meltdowns in three units and the release of radioactive material. The disaster killed nearly 20,000 people through direct effects of the quake and tsunami, displaced hundreds of thousands, and caused the second-worst nuclear accident in history after Chernobyl. It prompted global reviews of nuclear safety standards.
