The Fukushima Daiichi nuclear disaster was a 2011 nuclear accident at the Fukushima Daiichi Nuclear Power Plant in Ōkuma, Fukushima Prefecture, Japan. The proximate cause of the disaster was the 2011 Tōhoku earthquake and tsunami. The accident was triggered by the Tōhoku earthquake and tsunami on Friday, 11 March 2011.
What caused the radioactivity that was released in Fukushima?
In addition to the tragic toll of dead, injured, and displaced people, the earthquake and tsunamis badly damaged the Fukushima Dai-ichi nuclear power plant, eventually causing four of the six reactors there to release radiation into the atmosphere and ocean.
Is Fukushima still leaking radioactive waste?
The accumulating water has been stored in tanks at the Fukushima Daiichi plant since 2011, when a massive earthquake and tsunami damaged its reactors and their cooling water became contaminated and began leaking. TEPCO says its water storage capacity of 1.37 million tons will be full around the fall of 2022.
