Four years ago on 11th March the earth shook Japan. The magnitude nine quake went on for six minutes, the strongest the archipelago had ever recorded.
A terrible phase two followed. The epicentre of the quake was out to sea. The Pacific Ocean heaved, sending waves as high as ten metres charging towards shore.
The crushing force crashed along the northeastern coast; 18,000 people died. The natural catastrophe was far more than even monumental man-made structures could withstand.
The tsunami hammered the Fukushima Daiichi nuclear power plant, causing an electrical cooling system failure in reactor unit 1. An explosion smashed open the reinforced concrete containment shell the next day. The worst nuclear accident since Chernobyl in 1986 grew worse as emergency teams proved helpless to prevent a meltdown of three of the plant’s six reactors.
