Japan's Fukushima nuclear meltdown remembered The 2011 Fukushima nuclear accident in Japan has taught the world that our dependence on technology is a "double-edged" sword, the UN chief said on the fifth anniversary of the disaster. A massive earthquake triggered a tsunami which in turn caused an accident at the Fukushima Daiichi power plant described by the UN as "the worst emergency" of its kind since the Chernobyl disaster in 1986 in Ukraine. Calling on people to reduce their exposure to natural hazards, Ban Ki-moon warned that "a new era had clearly begun, in which technology and natural disasters can combine to create danger on a previously unimaginable scale."
