What happened in the Fukushima disaster?
Following a major earthquake, a 15-metre tsunami disabled the power supply and cooling of three Fukushima Daiichi reactors, causing a nuclear accident beginning on 11 March 2011. All three cores largely melted in the first three days.
What happened at Fukushima and why?
At the Fukushima nuclear power plant, the gigantic wave surged over defences and flooded the reactors, sparking a major disaster. Authorities set up an exclusion zone which grew larger and larger as radiation leaked from the plant, forcing more than 150,000 people to evacuate from the area.
How many deaths did Fukushima cause?

Where did the Fukushima disaster happen?
The March 11, 2011, Great East Japan Earthquake and tsunami sparked a humanitarian disaster in northeastern Japan and initiated a severe nuclear accident at the Fukushima Daiichi nuclear plant. Three of the six reactors at the plant sustained severe core damage and released hydrogen and radioactive materials.
How did Fukushima affect people?
In more than 140 papers, he and colleagues have documented the relatively low radiation exposure of Fukushima residents and the health impacts of the evacuation—a high death toll among the elderly, increases in chronic diseases, and a decline in general well-being.
What caused the Fukushima earthquake?
The earthquake was caused by the rupture of a stretch of the subduction zone associated with the Japan Trench, which separates the Eurasian Plate from the subducting Pacific Plate.
What are the after effects of Fukushima nuclear disaster?
Immediately after the Fukushima accident in 2011, radiation levels increased in food, water, and the ocean near the Fukushima Daiichi plant. Because of the threat of radiation exposure, some 150,000 people were forced to evacuate their homes. There were subsequently also multiple leaks at the facility.
How did the Fukushima disaster affect the economy?
The disaster disrupted supply chains and trade, with industrial production dropping sharply in the following months. Many of Japan’s nuclear power reactors were shut down for safety checks following the nuclear emergency at the Fukushima Dai-ichi plant, causing electricity shortages in some areas of East Japan.
How radioactive is Fukushima?
The NRA’s study found that the amount of radioactive cesium 137 was estimated at 20-40 petabecquerels between the space between the top and middle layers of the shied plug of the No. 2 reactor. That works out to more than 10 sieverts per hour based on readings of radiation levels nearby.

Is Fukushima still leaking radiation 2020?
In 2020, the Japanese government lifted bans on Fukushima seafood, saying they met safety standards that are stricter than American guidelines for cesium in food. The radiation levels offshore of Fukushima have dropped in the years since, but some of the reactors there are still leaking.
